pääkasvaimesta

Pääkasvain, also known as a brain tumor, is an abnormal growth of cells within the brain. These growths can be either benign (non-cancerous) or malignant (cancerous). Benign tumors, while not spreading to other parts of the body, can still cause serious problems by pressing on brain tissue. Malignant tumors are more aggressive and can invade surrounding brain cells.

The symptoms of a brain tumor depend on its size, location, and rate of growth. Common signs can include persistent headaches, nausea and vomiting, vision or hearing problems, seizures, and changes in personality or behavior. Neurological deficits, such as weakness in limbs, difficulty speaking, or problems with balance, can also occur.

Diagnosis typically involves a thorough medical history, a neurological examination, and imaging tests like MRI or CT scans. A biopsy may be performed to determine the exact type of tumor. Treatment options vary widely and depend on the tumor's characteristics. They can include surgery to remove the tumor, radiation therapy, and chemotherapy. In some cases, a combination of these approaches is used. The prognosis for a brain tumor is highly variable, influenced by factors such as the tumor type, stage, and the patient's overall health. Ongoing research continues to explore new diagnostic and therapeutic strategies for brain tumors.
