A brain tumor is a development of abnormal cells in the cells of the brain. Brain tumors can be benign, without cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which begin in the brain. Brain tumors can cause many symptoms. Physicians identify brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Targeted therapy uses drugs or other substances that attack cancer cells with less damage to normal cells. There are many types of brain tumors. Brain tumors may be slow-growing, not likely to spread, and not cancer. Both types of brain tumors can cause major problems by continuing and harmful normal brain tissue. A tumor might impact the brain in 1 or more methods. There are various types of brain tumors with many different symptoms, treatments, and outcomes. Call your health care provider if you have any questions about your symptoms and if they can be a sign of a brain tumor. Since the brain is enclosed inside the head which has a fixed quantity of space, a growing brain tumor can cause significant damages to the brain. Elements that identify the tumor quality consist of just how quickly the cells are growing, just how much blood is supplying the cells, the visibility of dead cells in the middle of the tumor, if the cells are constrained to a specific area, and exactly how comparable the cancerous cells are to normal cells.
