Surgery is an option for brain metastasis if there are one or two lesions that can be safely removed with surgery. If the cancer is in an area of the brain that is too risky to operate on, then radiation therapy could be used.
Before and during the surgical procedure, surgeons will use MRI studies to locate the tumor(s) for removal. Doctors may decide to use mapping techniques to help find the exact location of the tumor before you go in for surgery.
Depending on where the tumor is located, you might be a candidate for a less invasive form of brain surgery that uses a technique called neuroendoscopy. Instead of opening the skull, the surgeon can operate through a smaller incision using specialized instruments.
Your doctor can tell you which options are available for you.
