Ray: When I was being advised about radiation, initially there was mention of a feeding tube and physical limitations (no work, sports etc.) which was more than I wanted. A different level with few restrictions was proposed that I went through with, so my advice is to understand the costs involved with your treatment. Also, remember that free advice is worth what you pay for it.
Also if your cancer was not from HPV, learn about the role even mild alcohol use plays in this issue. You'll fight this all your life. With very good care and great attention on your part, that should be a long time. Best of luck, Tom
