Quite often for spinal tumors a form of radiation called cyber knife is used. I’m having cyberknife to L4 in a few weeks. Usually there’s 3-5 treatments on consecutive days lasting roughly 1 hour. You will need to have a CT scan so they can map out the treatment. Cyberknife sounds scary but it is like any other radiation however they can deliver higher doses because it is precisely targeted. I’ve had C2, L2,L3 and T12 cyberknifed and since they are all stable. Each cancer responds to radiation differently but it sure beats surgery.
Good Luck
