I would not suggest that I know any where near as much as your doctors, but I have talked with thousands of oral cancer patients at this point and watched their progress or demise. If it were me, I would be much more comfortable with an IMRT addition to the treatment. Studies show that more than 20% of stage one and two oral cancers have occult metastasis to the cervical nodes of the neck. That means that right now, no scanning technology that we have available, and no doctor feeling or looking at you can tell if you are one of those 20+%. Going through all this again a year from now is not something that you want to be doing. And recurrences can be difficult to deal with. Please be sure that your doctors and you discuss this until you are completely comfortable with the whole treatment plan. There are few chances to make another, different decision mid stream. Make the most informed one you can right now. We all wish you the best possible outcome from all this.
