If a reaccurence of a surgically removed brain tumor reappears is it better to treat it in its early stage with cyberknife,rather than surgery?

Tough question: Michael, I am sorry to hear about this. Regarding the best next step, I would discuss it with a Neurosurgeon, preferably the one who treated you the last time. Then, get a second opinion. Ask him/her specifically if Cyberknife would be an option. Remember that you are the patient and that it is your health that matters. Ask questions. Be proactive.
