Causes of brain cancer symptoms. Brain tumor at an early stage, how to recognize, symptoms

Brain cancer is a general name that includes different types of cellular structure, origin, clinical course and the results of therapy for malignant tumors, the initial location of which is brain tissue.

Brain cancer, which arises primarily in the central nervous system, is a rare disease. As a rule, it is observed in childhood up to 8 years. In terms of prevalence in children, it ranks second after malignant pathologies. hematopoietic system. The age of adult patients is 65 – 80 years. Men are affected slightly more often, but meningiomas are mainly observed in women.

Causes of the disease

The main cause of brain tumors is believed to be external factors: radiation, carcinogens, hormonal disbalance, viral infections. These irritants provoke genetic damage to cells, causing them to mutate.
The only proven cause of brain cancer is radiation. It is also believed that cell malignancy is influenced by:

aspartame – sugar substitute;
vinyl chloride is a colorless gas with weak sweetish smell, used in the production of plastics;
electromagnetic radiation from mobile phones;
high voltage power lines.

Some types of tumors are associated with genetic abnormalities. Pilocytic astrocytoma progresses from neurofibromatosis (von Recklinghausen disease), an inherited disease.

General clinical symptoms and first signs of brain cancer

Brain cancer causes headaches. This is a common sign of pathology and in the early stages serves as an initial signal. Headache as if bursting. Appears in the morning, after waking up, while tilting the head, with tense abdominals, sudden movements. Before its appearance, there is a feeling of heaviness, nausea, and pressure in the head. Over time, the pain is constant, accompanied by nausea and vomiting.

The remaining symptoms of the disease are associated with the part of the brain where the pathology originated. There are usually signs of mental illness different types. They are typical for older people:

disorders of consciousness of various types;
decreased concentration;
difficulties of perception, understanding of what is happening around;
conversation at a slow pace, it is difficult for a person to find words;
other mental disorders.

The disease is detected and local symptoms, which is manifested by impaired motor functions: immobilization of the left or right part of the body, twitching of a convulsive nature, hearing and vision disorders. If the pressure inside the skull increases, the symptoms also increase, creating a risk of the person falling into a coma.

Brain cancer in children. Symptoms of pathology

Signs of brain cancer in children, especially in their early age, have their own characteristics: they are characterized by rapid progression of the symptoms of the disease after a latent period of tumor growth due to an increase in the size of the cranium and the ability of the child’s brain to adapt.

Often the early stage is called wandering pain in the abdomen. They grow in waves general symptoms: the child has a headache, feels sick and vomits. Inhibition of mental processes is observed, especially in children. Symptoms weaken over time. Over time, focal neurological deficits appear, indicating that the certain fabrics brain.

Based on where the brain cancer occurred, the symptoms of the pathology may be as follows:

If neoplasms progress above the tentorium in the hemispheres big brain, in the early stages, signs of pathology are Jacksonian (local) epileptic seizures, less often - partial muscle paralysis, speech disorders.
As compression cerebrospinal fluid symptoms of pressure inside the skull are detected - vomiting, headache, nausea, dizziness, congestion on inner surface eyeball.
Brain cancer of the lateral ventricles is accompanied by vegetative-vascular disorders (disorders associated with damage to the peripheral autonomic nervous system) and the development of dropsy.
The subcortical-stem parts of the brain are characterized by cancer with mesencephalic quadrigeminal syndrome - disturbances in combined upward eye movement (upward gaze paresis), impaired ability of the eyes to converge on each other against the background of the development of cerebral hydrops.
Chiasmal gliomas are manifested by visual disorders - decreased acuity and impaired visual fields with symptoms of nerve atrophy during examination of the fundus and hormonal changes due to tumor damage to the hypothalamic structures.
For neoplasms pineal gland Premature sexual and physical development is noted, and oculomotor disorders occur.
Tumors affecting the cerebellum and medulla, develop dropsy, as they interfere with the outflow of cerebrospinal fluid - cerebrospinal fluid. Clinically, this occurs with hypertensive-hydrocephalic cerebellar crises - severe sharp pain in the head, taking a certain position of the head, prolonged muscle contraction. There are coordination disorders, frequent vibrations of the apples in the eye socket, and disturbances in the functioning of the brain nerves.

All patients with suspected cancer are examined by a neurologist, who uses additional examination methods to clarify the origin of the disease, location, and growth pattern.

Gliomas

Brain cancer from epithelial cells(gliomas, glial neoplasms) is the most common. Among gliomas, astrocytomas occur in 60% of cases, which come in four main types. The names and clinical features of each astrocytoma are presented in Table 1.
Table 1

*Type of astrocytoma*	*Kinds*	*Characteristic*	*Degree of malignancy*
Limited astrocytoma	pilocytic astrocytoma; pleomorphic xanthoastrocytoma; subependymal giant cell astrocytoma	Education with well-defined contours. Mostly children and young people are affected. This type of astrocytoma does not form new vessels, proceeds without necrosis and rarely with hemorrhages, and forms cysts. In 20% of cases, focal deposits of calcium salts (calcifications) are present, which can later degenerate into bone tissue.	I degree
Diffuse astrocytoma	fibrillary – the most common; protoplasmic – mostly cystic or superficial; gemistocytic – aggressive	This type of astrocytomas is mostly low grade. It grows slowly. About 10% of formations degenerate into more aggressive species. Calcifications are present in 20% of cases. Brain swelling is rare.	II degree
Anaplastic astrocytoma		The course is similar to the previous type of astrocytomas, but occurs with cerebral edema.	III degree
Glioblastoma multiforme		This brain cancer is widespread (about 50% of all astrocytomas). The onset of external symptoms is often short - less than three months pass before the pathology is determined. The outlook is disappointing; the pathology often recurs. It occurs with hemorrhages, necrosis, and spreads to the cerebral cortex.	IV degree

Oligodendroglioma affects adults aged 40–60 years, and sometimes it is detected in childhood. The tumor is a node delimited from the structures of the brain, in which there are foci of necrosis, cysts and calcifications. Brain cancer expands into the cortex, growing to varying depths, and is prone to recurrence.
Cancer of low malignant potential has best forecast currents.

Posterior fossa tumors

Part of the inner base of the skull, formed by bone back of the head, pyramids temporal bones and the body of the sphenoid bone, often affected by cancer in children. Pathologies that form in this place are medulloblastomas and astrocytomas of the cerebellum, ependymomas and gliomas of the brain stem.

In patients with tumors of this localization, clinical symptoms, which are a sign of a disorder of the cerebellar functions: drowsiness, disorder of coordination of movements, nausea, vomiting, increase in the size of the skull, blurred vision, convulsions, forced position of the head, gait disturbance, instability in the Romberg position (standing with feet together, eyes closed and arms extended straight in front of).

Medulloblastoma

Medulloblastoma is a malignant embryonal brain tumor. Often occurs in childhood and adolescence. In most children, the neoplasm clinically manifests itself in the first decade of life, with a peak incidence at 5 years of age.

This cancer is localized mainly in the region of the cerebellar vermis and often grows into neighboring tissues, most often into the lumen of the fourth ventricle. Accompanied by cystic changes, edema, necrosis, less often calcifications are present. Hemorrhages are rare.

The connection with the ventricular system causes its metastasis through the cerebrospinal fluid. In a third of patients, especially younger age, already at the time of diagnosis, metastases are determined. In approximately 5% of cases they are found outside the nervous system, usually in bone marrow, bones, lungs and lymph nodes.

Pilocytic astrocytoma

Pilocytic astrocytoma is the most common tumor in childhood, well separated from adjacent structures, grows slowly. Classified as grade I cancer, it recurs and spreads in rare cases.

Can hit not only bottom part, but also other brain structures, often the hypothalamus, optic nerves (optic nerve glioma). The appearance of signs of the disease depends on the location of the cancer.

Ependymomas

Ependymomas account for about 8% of all primary brain cancers. Children and teenagers get sick more often, the second age peak is at 30–40 years. The tumor develops from cells lining the walls of the cerebral ventricles and the central canal of the spinal cord.

This brain cancer grows slowly. The tumor is dense, does not contain cystic cavities, and is well circumscribed. The tumor displaces rather than grows into the surrounding brain tissue. Frequent signs are hemorrhages, large areas of calcification.
Ependymoma is designated as grade II cancer. The neoplasm metastasizes ventricular system and the membranes of the spinal cord.

Brain stem gliomas

Brainstem gliomas are completely heterogeneous neoplasms. In 60% of cases, trunk gliomas are defined as low-grade tumors, but structural heterogeneity often occurs even within the same formation.
Symptoms appear depending on how involved the pathological process nuclei of cranial nerves. Gliomas can be scattered, focused, or mixed.

Metastatic formations

Metastatic brain damage is a serious complication of cancer. Their frequency is high. Metastases are observed much more often than tumors that initially arise in the central nervous system.
The occurrence of secondary lesions occurs at any age, but more often occurs in patients 45–75 years old. Main sources of damage:

lungs – 50%;
mammary gland – 18 – 30%;
melanoblastoma (skin cancer that develops from pigment cells);
thyroid.

Brain metastases are stage IV of tumor development. The organ is affected multiple times.
The first signs of secondary brain cancer are different:

tumor-like variant - symptoms increase over some (short) time;
apoplexy variant, similar to a stroke - symptoms manifest themselves acutely and are usually associated with hemorrhage into a secondary focus or blockage of a brain vessel with a tumor clot;
remitting option - Clinical signs flow in waves, imitating vascular or inflammatory development.

The course of the disease is determined by a combination of local and systemic symptoms and is associated with the site of occurrence of the secondary focus, the degree of manifestation of edema located near the source of damage. Pain in the head, partial paralysis of muscles, mental disorders, seizures. Some patients have no symptoms.

Treatment of brain cancer

The primary method of treatment for most brain tumors is surgery - it is necessary to remove the tumor and determine its structure for further radiation and chemical therapy. During surgery, the formation is excised as much as possible, as far as its location, size and connection with important neuronal and vascular structures of the brain allow.

The leading role among conservative methods of therapy belongs to radiation oncology - brain cancer responds to radiation. Application experience has been accumulated drug treatment. Combination therapy in children it is supplemented with various methods of immune stimulation.

The incidence of malignant brain tumors among cancer diseases is 1.5%. And although they are less common than many other cancers, the first signs of brain cancer are often disguised as ordinary, common illnesses.

Therefore, when symptoms of a tumor appear, especially if they recur frequently, it is necessary to undergo an urgent examination. What are these symptoms, and how many of them can there be? More on this later in the article.

Malignant brain tumors are the most dangerous among oncological diseases

Features of brain tumors

Depending on the type of cells that were the source of the development of the tumor, tumors are divided into subtypes. For example:

meninges;
from cells belonging to the pituitary gland;
directly from brain cells;
tumors of the cranial nerves;
tumors that arise as a result of metastases from other parts of the body.

As the tumor grows, it increases in size and puts pressure on structures adjacent to it, causing symptoms that are called “primary (focal) or “local”. In addition, education leads to the emergence general violations in the brain, which manifest themselves with symptoms called cerebral.

General cerebral symptoms

Often education does not manifest itself in any way until serious changes appear in the brain.

It happens that the primary symptoms are so insignificant that they are not paid attention to, or are mistaken for another disease.

General cerebral symptoms of brain cancer

These include headaches, dizziness, nausea and vomiting. These symptoms occur when there is an increase in intracranial pressure or certain brain structures are compressed.

Headache

This symptom appears earlier and more often than others (about 90% of cases). With brain tumors, pain in the head at the beginning of the disease manifests itself in attacks. It is characterized by: constancy, high intensity and immunity to analgesics. It intensifies during coughing or sneezing, defecation, when turning the head, that is, with any physical stress.

Most often, a headache due to brain cancer is accompanied by a bursting sensation.

It is usually relieved by lowering intracranial pressure with medications.

Dizziness

As the tumor grows, it causes disruption of the blood supply to the brain structures. Lack of oxygen, hypoxia, causes dizziness. This may also be caused by compression of the cerebellum and disturbances in the vestibular apparatus. This is expressed in the form of rotation around its axis, as if a person is turning or, conversely, objects are moving around him. Such sensations can occur systematically, both in the case of a certain position of the head, and suddenly, regardless of the posture.

Vomiting and nausea

If the tumor arose in the midbrain, then, as it enlarges, it can put pressure on the vomiting center. As a result of his overexcitation, a person constantly feels nauseated. When intracranial pressure increases, nausea turns into severe vomiting. Sensitivity of the center different people not the same, so the severity of nausea and the intensity of the gag reflex will also be different. In some cases, a person is unable to even eat or drink water, since any irritation of the oral mucosa leads to vomiting.

Nausea and vomiting in brain cancer are especially pronounced in morning hours

Focal symptoms of a brain tumor

Symptoms in this group occur when pathological growth cells in a specific area of the brain.

It should be noted that in each case, some individual symptoms, different from those of other people.

In addition, some of them show themselves so insignificantly that people live with them for a long time.

Disorders of the autonomic nervous system. Occurs with increasing intoxication of the body, loss of control over tone vascular walls. They manifest themselves as lethargy, weakness, and indifference. It is difficult for a person to get up, move around, and he experiences changes blood pressure and arrhythmia.
Speech disorders (oral and written). They arise due to the destruction by tumor cells of the corresponding areas of the cerebral cortex. In the first stages of the disease, the speech of adults becomes slurred and unintelligible. The same thing happens with handwriting. In the future, there may be a complete loss of the ability to write and speak.

When the tumor affects the speech center, speech impairment occurs

Memory impairment. It also occurs when a tumor grows in the cerebral cortex. Depending on the speed of the pathological process, memory may be lost partially or completely.
Loss of sensation. Expressed in the loss of the ability of human skin to perceive any irritation from the outside. His tactile and pain receptors, he does not feel cold or warm. In addition, a person loses the feeling of himself in space, that is, he cannot determine in what position he is in this moment(with eyes closed).
Visual impairment. A decrease and then loss (complete or partial) of vision occurs when the tumor is located in the area of the optic nerve. In this case, the nerve impulse from the retina does not reach the cerebral cortex. If the neoplasm occurs in the cortex itself, in the place where what is seen is analyzed, then the nerve signals reach the cortex, but are not recognized. In this case, a person may not understand what is written or may not recognize surrounding objects.
Movement coordination disorders. Expressed in instability (especially without visual control), unsteady gait, inability to make precise movements.

A tumor of the cerebellum may cause unsteadiness in gait.

The occurrence of hallucinations. These can be both visual and auditory disturbances. Auditory hallucinations manifest as tinnitus, extraneous sounds or ringing. Visual ones are characterized by: flashes of light, dots, “floaters” or blurry images. The first symptoms occur rarely and, as a rule, are associated not with the disease, but with fatigue or overstrain (nervous or physical), weather, and so on. This leads to a significant loss of time.
Mental disorders. Changes in the psychological and cognitive sphere are expressed by symptoms such as: absent-mindedness, inability to concentrate, memory problems. In addition, a person whose tumor is growing becomes irritable, finds it difficult to communicate with others, and exhibits symptoms of psychopathy.
Manifestation of epilepsy and seizures. At the early stage of a brain tumor, mainly convulsive contractions of individual parts of the body or muscle groups are observed. As the disease progresses, seizures become more frequent and prolonged, affecting larger areas, and then give way to attacks of epilepsy. Such disorders are caused by prolonged stimulation of a certain area of the cerebral cortex.

At-risk groups

If such signs appear periodically, you should immediately contact a specialist and undergo an examination.

The most informative in this regard are computed tomography and magnetic resonance imaging.

MRI and CT are crucial stages in diagnosing a brain tumor

In case of timely treatment, brain tumors at an early stage of growth are cured in 80% of cases. How long do they live if it comes to stages 2–3? The indicators are halved.

Among adults who are most likely to develop a brain tumor are: the following groups:

having malignant formations in any organ;
those who have suffered a head injury;
With genetic diseases brain;
having constant contact with carcinogenic substances.

Brain cancer is a malignant tumor that develops in the brain tissue human body. Tumors are often differentiated by cellular structure. Cranial nerves are called neuromas, tumors from glandular tissue cells are called pituitary adenomas, tumors of meningeal cells are called meningiomas. All this is due to the development of the disease within the nervous system.

The result of treatment and a favorable prognosis directly depend on the stage of brain cancer. Despite the fact that it is cancer, it differs from all other types of cancer in its type and variety. This happens because the process does not go beyond the nervous system.

The degrees of brain cancer are determined using modern:

x-ray radiation;
magnetic resonance imaging (MRI);
positron emission tomography (PET);
computer diagnostics (CT);
cerebrospinal fluid studies;
blood tests for

These methods provide a clear enough picture to determine the stage of brain cancer.

The stages tend to change very quickly, and it is not possible to identify them, very often, and other brain regions are diagnosed only after the death of the patient, since in some cases the disease progresses very quickly.

Stage 1 brain cancer

Stage I brain cancer is characterized by relatively benign tumors that grow slowly. Cancer cells are similar to normal cells and rarely spread to surrounding tissues. Effectively surgical intervention and the body’s positive response to treatment gives hope for recovery and a long life if signs of a brain tumor are noticed at an early stage. One of the problems of brain tumors in the early stages of its development is mild symptoms.

First clinical manifestations:

headache;
weakness;
fast fatiguability;
dizziness.

Stage 2 brain cancer

At stage II of brain cancer, the cells also grow slowly and differ little from normal ones, despite this, the tumor has increased in size and the process malignant formation affects neighboring tissues. Stage 2 is characterized by slow infiltration into nearby tissues, recurrence and aggressiveness over the years.

Stages I and II are classified as “low grade”, therefore, after effective surgical treatment, the patient can live more than 5 years, provided there are no relapses. The symptoms become more pronounced and it is very difficult not to pay attention to them; new, more pronounced ones are added to the previous symptoms.

Symptoms of stage 2 brain cancer are as follows:

symptoms associated with gastrointestinal tract: nausea and vomiting (the presence of a gag reflex is associated with changes in pressure inside the skull);
there may be a feeling of general malaise in the body;
blurred vision;
convulsions;
epileptic seizures.

Brain cancer stage 3

The next stage, stage 3, of brain cancer is characterized by malignant tumors of moderate aggressiveness. They grow quickly and can spread into surrounding tissues; the composition of cancer cells differs from healthy cells. This stage of disease development represents a very serious danger for human life. At stage 3, doctors can recognize. , is already in pain severe form. Atypical class III tumor cells can actively reproduce, so treatment is complex and includes radiation, chemotherapy and surgery. The symptoms are gaining momentum, and even more pronounced ones are being added to all of the above symptoms.

Symptoms of manifestation malignant tumor brain at stage 3:

horizontal nystagmus (implies the patient’s running pupil, while the head remains painfully motionless and he does not feel the pupil running);
vision, speech, hearing change;
worsening mood, change in character, inability to concentrate;
difficulties with remembering, memory impairment;
difficulty maintaining balance when vertical position, especially when walking;
cramps, convulsions, muscle twitching;
numbness of the limbs, tingling sensation in them.

Stage 3 brain cancer, how long do patients with the disease live at this stage of the disease? After surgery, on average 1-2 years. Complex treatment can extend life by another year. With metastases to the brain and the development of secondary cancer, the tumor affects the entire brain, and it is extremely difficult to fight it.

Stage 4 brain cancer

Stage 4 brain cancer is characterized by rapid tumor growth and extensive infiltration. The cells multiply quickly and differ from normal ones. New vessels are formed to maintain rapid growth cells and areas of necrosis (dead cells).

The tumor grows rapidly, cancer cells multiply at a very high speed, while affecting the nearest brain tissue. The patient's condition worsens before our eyes. Surgery at this stage is most often impossible, since the tumor is located in vital areas of the brain, but in some cases, when the tumor is located, for example, in temporal lobe, surgery may be successful, and chemotherapy or radiation therapy will prevent the cancer cells from multiplying further. In all other cases, only part of the tumor can be removed, and further treatment occurs with the help of medications. A complete cure is not possible due to the rapid progression of the disease; you can only slow down the irreversible process. and adults stages III and IV refer to “ high degree" or high grade.

The last stage is very serious and scary, it leads to brain damage in which surgical intervention does not make sense. A person's vital functions cease to function normally. important functions body and with the help of potent drugs can only alleviate its suffering. In some cases, consciousness is completely lost, and the person falls into a coma from which he never recovers.

Stage 4 brain cancer, how long do patients with this disease live?

Most people diagnosed with this disease want to know what to expect from this disease, and how does the cancer respond to treatment?

The survival prognosis is influenced by many factors such as:

timely;
stages of brain cancer development;
sick;
age and gender of the patient;
the general health of the patient;
the presence of other diseases in the body;
emotional mood;
type of cancer;
cancer stage;
characteristics of brain cancer;
cancer subtype;
tissue or cell results (histology);
tumor size;
location of cancer.

There are also so-called cancer characteristics:

depth ;
tumor growth model;
type of metastasis (cancer spreads through nerve, blood or lymph vessels);
presence or absence of tumor markers;
presence of abnormal chromosomes;
ability to continue activities of daily living (EG).

Five-year survival rate of people with a brain tumor, the use of this term occurs very often when talking about survival prognosis. The assessment takes place over a certain period – 5 years.

This number represents the portion of the population who have been diagnosed with brain cancer, whether they have been cured or are still undergoing treatment. There are people who have lived with brain cancer for more than 5 years and they are on permanent treatment. It all depends on the state of a person’s health, his immune system and the nature of the disease. Survival rates vary depending on the type of cancer.

Important: Only the patient’s attending physician can select treatment and, based on treatment, establish a survival prognosis. Only the doctor is the only person who can answer all your questions.

Five-year survival rate prediction for brain tumors

Name of tumor	Survival rate in %, age
Name of tumor	22-44	45-54	55-64
(diffuse)	65	43	21
	67	55	38
Ependymoma/anaplastic ependymoma	91	86	85
Meningioma	92	77	67

In general, if cancer is detected at an early stage and treated promptly, the prognosis will be the best. But we must remember that cancer does not always respond to treatment the way we would like.

Be healthy!

Brain tumor is very serious and fatal dangerous pathology, which is important to recognize at the earliest possible stage of occurrence for timely removal. Otherwise, the chance of cure is very small due to the growth of metastases and the formation itself.

Types of tumors

Tumors, called neoplasms, come in two types - benign and malignant. In the case of appearance in the brain, both types can pose a danger, since even benign tumor will compress and experience vital areas in the brain.

The classic method of treating head formations remains their removal, which requires autopsy of the skull. It is possible to remove endoscopically, excluding trepanation, using special equipment. Other techniques not requiring trepanning:

Using ultrasonic waves affecting pathology
Radiosurgery, when the source of the disease is attacked by charged particles
Using a spatial scalpel for formations in hard-to-reach places

Benign brain tumors

In general benign formations called compactions from their own tissues, when cells begin to multiply abnormally, but the new cells do not destroy the healthy tissue around them.

No one knows the exact causes, but it is known that they contribute to the appearance of various diseases, injuries, exposure to radiation, genetic predisposition. Benign neoplasm usually grows slowly, does not penetrate other parts of the body, but as it grows, it begins to put pressure on adjacent areas, which affects the functionality and well-being of a person. As it grows, the pressure on nearby areas becomes critical, and there is a possibility of degeneration into cancer.

A benign tumor in the initial phase of development mainly manifests itself causeless dizziness, progressive headaches, may also be present:

Attacks of nausea with vomiting
Convulsions
Poor coordination in space
Anemia of arms, legs
Gaps in memory
Hearing and vision problems
Poor sensitivity
Difficulties with speech
Inability to concentrate
Attacks of hallucinations

Malignant brain tumors

Malignant, destroy healthy cells in their vicinity, while being able to circulatory system move throughout the body, penetrating more and more organs, disrupting their functioning, which ultimately leads to death. Such a formation is not clearly defined and has a tendency to uncontrolled self-generation with penetration and destruction of nearby tissues.

Depending on the type of pathology, different therapy is required; in oncology, it is customary to classify neoplasms according to the type of cells they consist of:

Nneuroepithelial are cells that grow from their own tissues in any part of the brain
Tunicale– derived from cells of the cerebral cortex
Neuromas- formations from nerve tissue
Pituitary adenoma– develops with injuries, infections, birth pathologies, in the pituitary gland from its cells

When the tumor is malignant, necrosis or tissue death occurs with bleeding. In case of aggressive growth there is a possibility fatal outcome for several months. Often major surgery removal is impossible due to a number of restrictions. Primary brain cancers are usually gliomas, which have different potential growth and degree of malignancy. The most dangerous tumor manifestation of the head is glioblastoma of the fourth stage of development.

Signs of early stage brain cancer

The main symptom is periodic headaches. Painful sensations in the head can arise for a great variety of reasons, therefore, they usually do not cause any suspicion. The person thinks it’s just overwork, the weather, stress, and takes a routine pill that relieves pain.

On the other hand, there is no point in doing an MRI after every attack of pain in the head. It is important to monitor your health and “catch” serious manifestations of possible pathology. If attacks occur very often, their intensity and duration increase, and medicines do not bring a noticeable effect, skipping a trip to the doctor can be expensive.

On what other symptoms If you suspect a brain tumor, you should pay attention to:

Nausea and vomiting in the morning
Dizziness or the impression of objects spinning around you
Problems with spatial orientation and coordination
Epilepsy
Hearing problems, temporary hearing loss
Visual disturbances: floaters and fog

Manifestations of a tumor in the brain in the first stages

Summarize. Headache is considered the first manifestation of a tumor in the brain. It is characterized by increasing duration and strength, accompanied by attacks of nausea and vomiting. The pain may occur in the occipital region, frontal region, temples, including only on one side. If the tumor affects the cerebellum, then symptoms of disruption of its functioning occur: dizziness, loss of orientation and coordination.

Initial phase in adults

In adults, both men and women, already in the early stages of the appearance of head tumors, a decrease in body weight is possible, as the processes of normal metabolism are destroyed. If atypical tissues have already entered the blood, then general weakness, high temperature, and changes in the skin are noted.

At greatest risk male population white race over 65 years of age. Factors that provoke the disease include:

Prolonged exposure to magnetic or radiation fields, usually due to professional activities
Previous exposure of the head to radiation
Presence of diseases that reduce immunity, such as HIV
Previous exposure to chemotherapy

First signs and manifestations in children

The development of brain gliomas in children is quite common. In more mature age the likelihood of occurrence decreases and increases only in old age. Signs of brain cancer in children are generally exactly the same - headaches, vomiting - as in adults, but there are some features associated with growth and adaptation child's body to the surrounding world:

Scoliosis appears with back pain
Slanty eyes
Growth slowdown
Incorrect gait, lack of precise coordination in space
Muscle cramps
Chronic vision problems

Diagnosis of brain cancer

If you have chronic, ever-increasing headaches associated with the symptoms mentioned above in the article, it is important to immediately consult a physician. If brain cancer is suspected, it is carried out biochemical analysis blood. There is a high probability that the pathology will be detected at the first stage by an ophthalmologist after examining the fundus. To make an accurate diagnosis, a comprehensive study is necessary, the main stages of which will be:

CT scan
Vascular angiography
Taking cerebrospinal fluid (puncture)
Carrying out electroencephalography

Consequences of a cancerous tumor in the head and the possibility of recovery

Progress in the application of methods and means of medicine is constantly evolving, modern equipment and the qualifications of doctors make it possible to carry out very complex operations, including on the brain with and without opening the skull. However, even the most innovative clinic will not be able to help late stages diseases, therefore early diagnosis is the most important point in the treatment of brain cancer and ensures 75-80 percent survival of patients in the next five years. The outcome of treatment and further recovery are also affected by:

Tumor location
Absolute size of formation
Patient age
Presence of metastasis to other organs
Malignancy/benignity
Patient immunity
Tumor type

The effects of treatment on children can be fundamental to the child's overall development. This occurs if the parts of the brain responsible for development and function undergo therapeutic changes. various functions organism, for example, visual perception or information processing. In children with such deviations after therapy, the following may be recorded: poor eyesight, paralysis, underdevelopment, psychical deviations, muteness, deafness, and in the worst case, death.

Prevention of brain cancer

Unfortunately, despite all the efforts devoted to the fight against cancer, today it still remains incompletely studied. IN to the fullest The reasons for its appearance have not been identified - that straw that, falling on a camel’s back, triggers the formation and division of atypical cells that kill the body, but which the body itself considers its own.

Therefore, recommendations for the prevention of brain tumors are the most general character. It is necessary to lead healthy image life, eat a balanced diet, less carcinogens in food, do not get a head injury, do not be exposed to radiation, exposure to strong hormones, and of course, consult a doctor at the first sign.

During the pathology under consideration, increased division and modification of the cells that make up the brain and its components occur: nerve fibers, meninges, blood vessels. Malignant cells can also be brought into the brain through the blood or lymph flow from cancer-affected organs.

This tumor tends to grow into nearby tissues, negatively affecting the functioning of brain structures. This is manifested by vegetative, psychological and intellectual disorders.

The main causes of brain cancer - what factors provoke the development of a tumor?

To date, the exact cause of the disease in question has not been established.

But there are a number certain factors which often precede the development of brain cancer:

Staying in the area of radioactive radiation for a long period of time.
Work in conditions that involve regular contact with chemical agents.
Injury to the skull.
The presence of a similar pathology in close relatives is a genetic factor.
Alcohol addiction.
Consumption of products containing GMOs.
Tobacco smoking.
Diseases that affect protective functions body. First of all, this includes HIV.

Video: First signs of brain cancer

The risk of getting a malignant neoplasm in the brain increases with:

Representatives of men's ball.
Young patients under 8 years of age.
Persons over 65 years of age.
Those who sleep with mobile phone near the head.
Liquidators of the tragedy at the Chernobyl nuclear power plant.
Patients who have undergone internal organ transplantation.
Undergoing chemotherapy as a method of treating a tumor, regardless of its location.

Types of brain oncology and features of their development - degrees of brain cancer

There is a fairly broad classification of the disease in question.

1. Depending on the location, malignant neoplasms are:

Intracerebral. They are diagnosed in the substance of the brain.
Extracerebral. Cancer cells do not affect the brain cavity - they affect its membranes and cranial nerves.
Intraventricular. The tumor spreads to the ventricles of the brain.

2. Based on the etiology of tumors, the following brain cancers are distinguished:

Primary. They appear as a result of mutations in the cells of certain components that are located inside the skull. Degenerative changes can affect bones, nerve fibers, blood vessels that supply the brain, Gray matter etc. They are in turn divided into two large groups: gliomas and non-gliomas. Each of these groups can be represented various types malignant neoplasms which will be described below.
Secondary. They develop against the background of metastasis of other internal organs.

3. Primary brain tumors come in several types:

Astrocytoma. The culprits of this disease are astrocytes - auxiliary cells of the brain. Men are more susceptible to this pathology.
Oligodendroglioma. It is extremely rare due to the transformation of oligodendrocytes.
. On practice this type intracerebral tumors are most common. Research always confirms the presence of modified oligodendrocytes and astrocytes in this type of cancer.
Lymphomas of the central nervous system. Cancer cells are located in the lymph vessels inside the skull. According to studies, this type of brain tumors often occurs against the background of weak body defenses or after an internal organ transplant.
Pituitary adenomas. This type of neoplasm is rarely malignant. It is often found in women, and it manifests itself as disruptions in the functioning of the endocrine system: obesity, increased hair growth, long-term healing wounds, etc. In children this disease manifests itself as gigantism.
Meningiomas. Formed from mutated cells arachnoid brain. They are capable of causing metastasis.
Ependymoma. The cells responsible for the synthesis of cerebrospinal fluid undergo modifications. They come in several classes:
- Highly differentiated. The parameters increase quite slowly, metastases are not observed.
- Moderately differentiated. Like the previous class, they are not capable of metastasizing, but the tumor grows faster.
- Anaplastic. Cancer cells divide quickly enough, causing metastases.

There are 4 stages of brain cancer:

First. The cells of the pathological neoplasm are not aggressive, they are not prone to spreading. Due to mild symptoms (loss of strength, slight dizziness), identifying the disease in question at this stage is problematic.
Second. Growth and increased cell degradation are recorded. Nearby tissues, lymph nodes, and blood vessels are involved in the pathological process. Surgical treatment does not always give the desired results.
Third. Patients complain of severe and frequent headaches, dizziness, and increased body temperature. In some cases, disorientation in space and deterioration in the quality of vision occur. A common occurrence is nausea and vomiting. After appropriate diagnostic measures, the doctor may declare the tumor inoperable. In general, the prognosis for stage three brain cancer is unfavorable.
Fourth. Headaches are intense, constantly present, and difficult to relieve with medications. In addition, hallucinations, epileptic seizures, and fainting are observed. There are disturbances in the functioning of the liver and lungs due to active metastasis. At this stage, the tumor is not operated on, and all treatment is aimed at eliminating the symptoms.

The very first signs and symptoms of brain cancer – when to sound the alarm?

The disease in question in the early stages manifests itself with nonspecific symptoms. Similar signs are present in some other diseases associated with the functioning of the muscular, central nervous system, and internal organs.

Therefore, the presence of at least one of the conditions described below is a reason to consult a doctor:

Nausea and vomiting, which do not depend in any way on the time of eating. If vomiting begins soon after eating, the vomit will contain undigested pieces of food. The presence of bile indicates that the patient has not eaten anything for a long time. main feature this symptom– lack of relief after vomiting, as happens in case of poisoning.
Night and/or morning headaches painkillers that painkillers cannot cope with. When in an upright position, the pain subsides. When you move your neck or body, the pain intensifies. As the tumor progresses, the pain in the head does not stop.
Loss of ability to analyze received information.
Difficulty remembering.
Impaired concentration.
Inadequate perception of events.
. IN specified process the whole body may be involved, and in some cases the person loses consciousness with short stop breathing.

The symptomatic picture of this pathology is divided into 2 large groups:

1. General cerebral signs

Includes the following conditions:

Violation of wakefulness and sleep patterns. The majority of the time, amid headaches and weakness, a person sleeps. Waking up can only be triggered by the desire to go to the toilet. After the patient wakes up, he is unable to navigate in time and space, his thoughts are confused, and he does not recognize the people around him.
Bursting headaches. After taking diuretics, the pain decreases, but does not completely disappear. Peak pain falls in the morning. This is due to swelling of the meninges during sleep.
Negative reaction of the visual organs to light rays: lacrimation, sudden closing of eyelids, pain in the eyes, etc.
Dizziness. The patient experiences a feeling of “wobbly feet,” in which the ground under his feet seems soft and/or sinks.

2. Focal signs

Paresis or paralysis – when a cancerous tumor is localized in the motor cortex. Often only one half of the body is affected.
Lack of adequate reaction of the pupils to the light beam.
Inability to write even a few sentences.
Autonomic disorders: increased sweating, frequent fainting due to low blood pressure, etc.
Poor coordination of movements: staggering when walking, standing.
Difficulty recognizing objects.
Poor understanding of the meaning of the text read.
Shifting pupil syndrome.
Hearing problems. In some cases this leads to deafness.
Inability to recognize or pronounce individual sounds, words.
Errors associated with visual function. In addition to deterioration of vision and double vision, there may be difficulties in determining the exact shape and parameters of surrounding objects.
Loss of sensation in certain areas of the body.
Hormonal disruptions when the pineal gland or pituitary gland is involved in the pathological process.
Psychological disorders: the patient becomes too irritable, sometimes aggressive.
Difficulty with thinking.
Various types of hallucinations:
Auditory - when involved in oncological process temporal zone.
Visual – if the tumor is located in the occipital region.
Olfactory – in case of damage to the anterior parts of the frontal lobe.
