A tumor that begins in the brain is known as a primary brain tumor, according to WebMD. Some primary brain tumors are benign. Malignant, or cancerous, brain tumors often spread to other areas of the body. Some brain cancer patients do not display symptoms until a tumor becomes large and causes serious health problems. Symptoms of brain tumors include headaches that do not get better with typical treatments, changes in hearing or speech, trouble walking, changes in personality, difficulty concentrating, weakness in a particular area of the body, vision changes, problems with balance, numbness, memory problems and seizures.

Brain tumors are diagnosed through neurological examinations and X-rays or other imaging of the brain, WebMD notes. When a tumor is found, a biopsy is performed to determine if the tumor is malignant. Cancerous brain tumors are treated through some combination of surgery, radiation therapy and chemotherapy. Patients often work with therapists after treatment for brain cancer to restore balance, speech, strength and ability to perform daily activities.
