I have had several different surgeries during the past 3 years and the closest I get to his planned treatment is the Stereo-tactic. Mine was to the original tumor bed of a previously removed brain tumor. It really can't be compared to your brothers plan because it appears that he is having both types of surgery at one time. Again, I'm guessing that they are using this treatment to get him radiation without affecting previously radiated tissue. The Stereo-tactic is really effective for brain tumors but I can't say on head and neck cancer. I am on my second chemo program now, but I also got chemo all last summer for lung metastases. What Hospital is he at?
