First of all, welcome. Secondly, give up the guilt - it doesn't get you anywhere, you didn't go asking for cancer and if anything you did caused it, I doubt that was your intention. Anyway, that horse has bolted. I put off having my mammogram - if I hadn't my cancer probably wouldn't have been picked up as it would have been too small...then much bigger. Go, figure.... I was ticking everything off the list including the bowel cancer test. The good news is that you have found it. There's enough else to deal with - ditch the guilt and don't let anyone load it on you. Take care.
