The symptoms of brain tumors depend on their size and location in the brain. Symptoms often are caused by damage to vital tissue and pressure on the brain as the tumor grows within the limited space in the skull. They may be caused by swelling and a buildup of fluid around the tumor, a condition called edema. Symptoms also may be due to hydrocephalus, which occurs when the tumor blocks the flow of cerebrospinal fluid and causes a build-up in the ventricles.
Brain cancer is a serious form of cancer that occurs when there is an uncontrolled growth of cancer cells that form a malignant tumor in the brain.Normally, cells in the brain that are old or damaged will stop dividing and die. These cells are replaced by healthy young cells. Brain cancer occurs when old or damaged cells continue to divide and multiply uncontrollably. These abnormal cells eventually develop into a malignant mass of tissue (tumor) and crowd out and destroy healthy cells in the brain. As brain cancer grows, it interferes with vital processes and functions of the brain and spinal cord.
Brain Cancer Symptoms
- Changes in mental function
- Seizures (especially in older adults)
- Weakness in one part of the body
- Headaches caused by brain tumors may
- Be worse when the person wakes up in the morning, and clear up in a few hours
- Occur during sleep
- Occur with vomiting, confusion, double vision, weakness, or numbness
- Get worse with coughing or exercise, or with a change in body position
Brain Cancer Treatment
Treatment for brain cancer should be individualized for each patient. Treatment plans are based on the patient’s age and general health status as well as the size, location, type, and grade of the tumor. In most cases of brain cancer, surgery, radiation, and chemotherapy are the main types of treatment. Often, more than one treatment type is used. The treatment types are further described below.
