While benign tumors may not be as serious, they may still cause problems in the brain. The cause of brain cancer and brain tumors is not fully understood. Some believe that smoking, genetic factors, environmental toxins and radiation may play parts in the development of brain tumors, but research is still being conducted to determine the exact cause of brain cancer. HIV infection may also be linked to brain cancer, as well as radiation to the head.

Symptoms of brain cancer may be caused by the tumor pressing on or disrupting other parts of the brain, thus keeping them from functioning properly. Swelling of the brain may also cause some of the symptoms.

Common symptoms of brain cancer may include headaches, weakness, clumsiness, difficulty walking and seizures. Other symptoms may include a decreased alertness, memory problems, trouble concentrating, nausea, vomiting, vision and speech problems, and changes in intellectual and emotional states.

Diagnosis may be performed using a CT scan of the head to determine if brain tumors are present. Other methods may be used in diagnosing brain cancer as well.

Treatment for brain cancer may vary among patients. The health and age of the patient, as well as the location, size and type of tumor may influence the type of treatment used. Brain surgery to identify and remove a tumor may be required for patients with brain cancer.

Radiation therapy and brain cancer chemotherapy may be used to kill cancer cells in brain cancer patients. Other methods may also be used to treat brain cancer. Diet and lifestyle changes may support a cancer-free recovery.
