Tumors of the brain

Medicine2

There are benign and malignant tumors of various parts of the body, as well as the brain. Even benign brain tumors are a huge danger. Sprouting and destroying tissues, the tumor causes compression of the brain, cranial nerves and blood vessels that feed the brain, seriously damaging its structures, contributing to its swelling and increased intracranial pressure. In the absence of treatment, edema ends with death.

Symptoms

Symptoms can be very different. The most common are:

  • Strong, gradually growing headaches.
  • Circulatory disorders.
  • Nausea and vomiting.
  • Dizziness, impaired orientation in space, short-term fainting.
  • Convulsions.
  • Behavior changes.
  • Paralysis.
  • Changes in the nature of sensations (visual and hearing impairments to blindness and deafness).
  • Changing the nature of breathing.
  • Changes in the fundus.

The first symptoms of the disease can be very different, they depend on the location of the tumor. In the elderly, the first symptom of the disease may be a sudden seizure. Usually seizures are accompanied by severe headaches, especially in the morning, and sometimes by neurologic symptoms (violation of gait, coordination, paralysis of individual nerves or limbs).

A characteristic symptom of a brain tumor is the constant progression of symptoms (for several months or years). For example, there is a weak headache that gradually becomes unbearable.

Causes

Primary brain tumors are the formations developing from the substance of the brain, its roots, membranes, brain or nervous tissue, pituitary cells (glioma, meningioma, neurinoma and adenoma). The tumor of the pituitary gland is accompanied by disorders of menstruation, the production of adrenal hormones, the activity of the thyroid gland. Secondary tumors are formed from the bones of the skull or come from tumor-like lesions of internal organs. Most often the brain metastasizes lung cancer, sometimes - cancer of the stomach, intestines, breast and kidneys.

Meningioma of the brain - the most common benign brain tumor, arises from its shells, is characterized by very slow growth. Usually it is observed in the elderly, women are twice as likely as men. Malignant tumors, for example, medulloblastoma, grow much faster. In addition, they destroy and nearby tissue. In adults, malignancies develop in the cerebral hemispheres and cortex, in children in the posterior cranial fossa.

Treatment

If the tumor localization allows, surgery is performed. If the tumor is inoperable, use radiation therapy, chemotherapy and drug therapy in various combinations. The use of cytostatic drugs (drugs specifically designed to treat cancer) or radiation therapy does not always bring a positive result.

If the head often hurts, (especially with frequent and severe pains accompanied by vomiting), there is a disturbance in the activity of the senses, it is necessary to consult a doctor.

The doctor will ask about the symptoms, as well as the nature and severity of the functional disorders. He will send to the oculist for examination of the fundus. If a brain tumor is suspected, the doctor will refer you to a specialist for necessary research.

The severity of the disease depends on whether the tumor is operable. Even if it is of a malignant nature, but the localization allows for an operation to remove it, the results of the treatment will be good and the patient will recover. The prognosis is good in case of meningioma. The fact is that it grows very slowly, and, as a rule, the operation for its removal is successful. Often after surgery to remove the tumor, there are violations of physical and mental functions. Sometimes a patient has to re-learn to perform simple everyday work.
