While it can go anywhere, soft palate cancers can become nasopharyngeal cancers which is not a fun place to be, as well as to the neck and even to the spine in advanced cases. Tongue cancers TEND, BUT DO NOT ALWAYS, like to go to the floor of the mouth and the neck. While I am sure there are printed articles in the journals on this, I can't put my finger on one right now. Needless to say, it isn't something that you should be worrying about, and a journal article and the results therein, may not even apply to you. I like the sound of your doctor. He says the right things, has the right perspective, is positive, and stays away from statistics and predictions. My kinda guy.
