Brain Metastasis

A brain metastasis is a tumor that arises in the brain and has spread from a primary cancer elsewhere in the body. They are common; each year, 20-40% of cancer patients will develop at least one brain metastasis. 

While new brain metastases can be a scary and discouraging development, the good news is that they can usually be treated or controlled. In fact, the survival of a cancer patient is generally not determined by spread to the brain but rather by control of the primary cancer outside of the brain.

Treatment for brain metastases begins with either surgery (a biopsy or a removal by craniotomy) or radiosurgery. Craniotomy tends to be used for large metasases that are pushing on the surrounding brain, while radiosurgery is better suited to smaller lesions - especially when there is more than one. Most patients will need additional therapy after surgery, usually a chemotherapy agent targeted against the cancer of origin. There are also promising new therapies available for brain metastases, including immunotherapy and laser interstitial thermal therapy.
