How to recognize brain cancer?

Malignant neoplasms of brain tissue include tumors inside the skull and spinal canal. The oncological process is characterized by uncontrolled and atypical cell division.How to recognize brain cancerit depends on the class and variety of oncoforming.

Statistics

This pathology can develop in two main forms:

  1. Primary lesion - when the neoplasm is formed from mutated brain tissues.
  2. Secondary lesion - the oncological process in this case is a consequence of the metastatic spread of cancer cells from distant organs and systems. Penetration of pathological elements can be made by lymphogenous or bloodway.

According to the latest classification, specialists in the histological structure distinguish 12 groups of cerebral neoplasms. In most cases, glioma is diagnosed in cancer patients (60%). This type of head tumor grows directly from the brain tissue and has an unfavorable prognosis. The second oncological tumor according to the frequency of diagnosis is meningioma, the source of which is the cells of the cerebral membrane.

Many people have a logical question,how to recognize cancerat an early stage? To do this, the doctor compares the subjective complaints of the patient and the data of objective research.

Early signs of brain cancer

The initial stage of the disease can be identified only by the presence of cerebral symptoms of oncology:

Headache attacks:

This is considered the earliest sign of the malignant process of the central nervous system. Painful attacks have a different intensity. They are usually activated in the afternoon and at night.

Also, pain intensification occurs during physical or mental overstrain.

Vomiting:

Typical for such cancer patients is the presence of vomiting without concomitant nausea. In most cases, vomiting is not associated with eating and is observed in the morning or against a background of migraine.

Dizziness:

Often patients complain of a sudden feeling of the rotation of surrounding objects.

Mental disorders:

Clear consciousness is maintained in patients with meningeal tumors. In this case, some patients distort the process of thinking, remembering or perceiving. For example, it may be hard for a cancer patient to recall recent events, his address. He becomes apathetic or on the contrary - hyperexcited.

Epileptic seizures:

Seizures that first occur at the age of over 20 years are a direct reason for a visit to a neurologist. In the case of a malignant lesion, this symptomatology retains a tendency to an increase in the number of seizures.

Impairment of vision quality:

In patients, there is a progressive decrease in visual acuity or a fog before the eyes.

Distortion of sensitivity:

The slow disappearance of the tactile or pain sensitivity of the skin can also be an early indication of the development of the head tumor.

Exact tumor symptoms

Focal signs of tissue damage of the central nervous system depending on the location of the tumor include:

  • Frontal lobe:

Local headache, epileptic seizures, mental disorders, paresis of facial muscles and decreased visual acuity.

  • Pre- and postcentral gyrus:

Pathological seizures of swallowing, licking and chewing. Patients have paralysis of the facial and sublingual nerves and discoordination of limb movement.

  • Temporal fraction:

In the initial period of the disease, patients note the disappearance of taste and olfactory sensations. Also, such patients have disruption of the trigeminal nerve and convulsive conditions.

  • The dark share:

Reduced deep sensitivity and gait coordination. The patients noted the impossibility of reading, writing and speaking.

  • Occipital Part:

The main symptom is a visual impairment.

  • Pituitary:

A key sign of this defeat is a radical change in the hormonal balance and blindness.

What tests will help in time to recognize brain cancer?

For timely diagnosis of brain cancer, the doctor, after clarifying the patient's complaints, appoints the following procedures:

  1. A common and expanded blood test, which also includes determining the exact concentration of platelets.
  2. Ultrasound examination of internal organs.
  3. Computer and magnetic resonance imaging.

Determination of the number of oncomarkers in the diagnostic complex of procedures is not very effective, since oncomarkers on brain cancer do not have high specificity of the study. This procedure is mainly used to control the effectiveness of anti-cancer treatment.

Prevention of disease

To prevent malignant degeneration of brain cells, experts recommend following the following rules:

  1. Every year, take preventive medical examinations.
  2. To refuse from bad habits.
  3. Balance the daily diet for vitamin and mineral content.
  4. Exclude the impact of carcinogens on the body.
  5. Spend more time outdoors and engage in physical culture.
