That is definitely a tough one to call! Obviously it is a choice only you can decide upon. The only advice I could suggest is to carefully consider how your cancer is now - and what is the prognosis like for you as it stands today. Did anyone offer any other treatment options? The best thing to do is to talk it over with family/friends and of course - ask plenty of questions to your health care professionals. I know I would feel the same way as you do, if I were only in the "observation" group. I figure if I were to ever put my body through that kind of rigorous treatment, after already going through hell with previous treatments - it had better not be for "nothing" (aka: observation)! I wish you all the best in whatever your choice may be. Please keep us posted on your decision and how things are going.
