Sometimes, however, the tumor is a secondary cancer , that is, made up of cells from a cancer that developed elsewhere in the body and spread to the brain. No one knows the exact cause of primary brain cancer. One possibility is that as the brain and spinal cord were forming, a problem with the cells occurred. Secondary brain tumors are the result of different cancers that have spread. It is easier to cure primary brain tumors than secondary ones.
Treatments vary depending upon the type and location of the tumor.
If it is possible to remove a tumor, surgery is usually performed, followed by radiation. Some patients receive chemotherapy as well. The chance of surviving a brain tumor depends on its type, location, and treatment. But there is a very good chance that if the tumor can be removed and additional treatment is given, the cancer can be cured. For specific medical advice, diagnoses, and treatment, consult your doctor.
