Brain tumor refers to a mass or growth of abnormal cells in the brain. These cells can be cancerous (malignant) or non-cancerous (benign). Brain tumors can develop from various types of cells, such as astrocytes, neurons, and glial cells. They can also originate from other parts of the body and spread to the brain (metastatic).
Brain tumors can cause a range of symptoms depending on their size, location, and whether they are cancerous or not. Some common signs include headaches, seizures, changes in vision or hearing, memory problems, and difficulty with balance or coordination. The severity and duration of these symptoms may vary.
Treatment for brain tumors can involve surgery to remove the mass, radiation therapy to kill cancerous cells, chemotherapy to destroy cancer cells throughout the body, and targeted therapies that specifically attack cancer cells. The choice of treatment depends on various factors such as the type, size, location, and aggressiveness of the tumor.
In summary, brain tumors are abnormal growths in the brain that can cause a range of symptoms and require different treatments depending on their characteristics.
