I just has a successful operation to remove cancer from my lower left tongue - succesful because nothing found in my lymph nodes and clean margins. However, because of the depth of the tumor - .9 cm, the radiologist is recommending radiation. My encologist can go either way so I'm not exactly sure what to do. I will get a second opinion. While I want to be aggressive as I can, I'm also reading all of side affects of radiation and wondering if I shouldn't just keep a close watch for the next several years.

Any thoughts?
