I am confused with what I have read on the Cancer TResearch UK forum which says that a W&W approach means you do have cancer when if fact, there is no evidence of it in my husband's case. He  had a CT scan which picked up "something" and went on to have a colonoscopy which showed no sign of cancer but did indicate he has an inverted opening to his appendix whch the Dr performing the colonsoscopy thought might have been mistaken for a growth. . The Consultant who saw him after the colonoscopy  said he MIGHT have a tumour in his appendix but they don't know for sure and added that there are no signs of any abnormal cells. He went from advising surgery at the start of the review,  to saying that a Watch and Wait approach would be reasonable given that my husband now has no symptoms (original symptoms indicating possible colon cancer have now gone away acompleyely and that has been the case for a few months now) and is feeling very well.  Husband is due to have another CT scan next month. 

Where should we go for another opinion as the op will be a Just in Case appendectomy and possible removal of some of his colon which, since he is in his early 70's is a major surgery and a fairly lomg recovery time.If it is not necessary, he'd rather avoid it!
