You need a multidisciplinary approach to all this. These doctors are a one note song. Surgery, and if needed more surgery. Bottom line is you are in a place where this likely needs to be treated with more than this one medium. A comprehensive cancer center will give you a real plan that will hopefully irradicate this once and for all. It may include radiation and more, but at the end of it you will have the best chance for a long and healthy life. The combination of delays on your part, and incomplete treatments on those of the people you have been working with have put you in a less than desirable position. Get to a place where experts can pick up the pieces from here. You only get so may chances to do this right, it is a very unforgiving disease.
