Causes of Metastatic Brain and Spinal Cord Tumors
About half of metastatic brain and spinal cord tumors are caused by lung cancer. Leukemia, lymphoma, breast cancer and gastrointestinal cancer may spread to the leptomeninges, the two innermost membranes covering the brain and spinal cord.
Treatment depends on the type and stage of disease, and may include surgery, radiation therapy or chemotherapy, or a combination.
