There are so many other things it could more likely be and not something nasty like cancer although its the first thing we think of ,I thought the same after having a positive fit test and lots of other symptoms like a elevated CA125 blood test and unexplained weight loss I convinced myself it was cancer I was sent for a colonoscopy I was so scared but thankfully they only found a polyp fibroids and diverticulitis they took a biopsy but it was fine so I know its easy to start thinking negative thoughts but chances are he'll be fine try not to worry .

ps he does have a polyp that had shown a couple of years ago when he had his stoma operation and glad that you are ok too
