The most frequent symptom of brain tumor - headache. Permanent headache, increasing in the morning hours, speaks of elevated intracranial pressure. Other signs of increased intracranial pressure are nausea, vomiting and drowsiness. Brain tumors often cause a weakening of memory, violation of attention, apathy and other changes in the behavior of the patient.
Many symptoms are due to the location (localization) of the tumor in the brain. For example, violation of speech arises in cases where the neoplasm develops in the left frontal or left temporal share.
Tumors located in the left hemisphere of the brain cause weakness in his right hand and leg, while the tumors of the right hemisphere lead to a decrease in force in the left hand and leg.
The tumors of the occipital share cause the narrowing of the fields of view, as a result of which, when walking, the patient rises to objects, and when driving, the car often falls into emergencies.
Tumors developing near the optic nerves (for example, adenoma pituitary gland, meningioma, etc.) also lead to violations of vision.
Remember, above are only the most common symptoms of brain tumors. If any of them, a doctor's advice and survey is required.
What differ benign and malignant brain tumors
Brain tumors are benign and malignant.
A benign brain tumor is characterized by slow growth, for a long time may not increase at all in the amount. Often such a tumor does not exhibit in any way, and the patient does not suspect the development of the disease. Symptoms, for example, headache, appear only when the tumor reaches impressive sizes.
The most common benign brain tumor - meningioma. Benign tumors after complete deletion, as a rule, do not appear again, but in the case of incomplete removal can grow in the same place.
The malignant brain tumor is rapidly increasing in size and already at the initial stage it causes edema and squeezing the brain. Symptoms also appear at an early stage of the disease, the patient's condition is worse rapidly. Malignant tumors even after complete deletion appear again. Some types of benign tumors over time are reborn (transformed) into malignant.
Primary brain tumors and metastases in the brain
Primary brain tumors and metastases in the brain: what they differ? The main difference is the primary tumors are formed in the brain itself, and the source of metastase is a malignant tumor of another body part.
Primary tumors (even malignant) do not apply to other parts of the body, exceptions are extremely rare. In addition, primary tumors can be benign (meningioma) and malignant (globlastoma), while metastase is, by definition, malignant tumor.
