The neurosurgeon who did my original surgery on 6/6/12 wanted to wait on this too. When I told him Dr. Danish was recommending it right away, he did not disagree. Doctors tend to practice the way they were taught in medical school and Gamma Knife is new-fangled technology. My hunch is your doctor hasn’t done a lot of Gamma Knife procedures. Find a Gamma Knife center where that’s all they do. Dr. Danish actually teaches it at Rutgers Medical School. You need to seek out a second opinion (in my opinion).
