Brain cancer usually exists in the form of a tumor, which is a growth of abnormal cells in the brain tissue. According to the National Cancer Institute, there are few known risk factors for brain and central nervous cancers, but several conditions may increase the risk of developing certain types of brain tumors: radiation exposure, vinyl chloride exposure and having certain genetic syndromes. There are no screening tests for brain cancer.
If a tumor is located in or near a critical structure of the brain, this treatment is delivered in small, daily doses over several weeks and is then referred to as stereotactic radiation therapy.
Neurosurgeons and radiation oncologists work closely together in delivering these treatments. Clinical studies have shown that stereotactic radiosurgery results in improvement and control of certain tumors of the brain compared to other, more traditional methods of radiation treatment. In addition to brain tumors, stereotactic radiosurgery has been used successfully in treating other conditions.
