My Dr. says there may be microscopic cancer that scans won't show, and that is why he recommends radiation. Could someone who has been thru 6 weeks or more rad. tell me what to expect as each day passes and how sick they got. I know there is not much of a choice, but as least I will know what I'm in for. Has there been someone who chose not to get radiation and did or did not regret it? I have also read that they want you to start rad. within 100days after sugery, is this also true?
