I'm sure I have cancer. I'm 67 and after explosive diarrhoea - loads of inch-long bits of stool - yesterday and the day before - I saw red blood on a lot of them. Two days before this I thought I was going to pass wind but just mucous poured out. I do have haemorrhoids internal and external but have never seen red blood on the stools before. I had one of those emergency two-week wait appointments last November (due to nausea and pencil thin stools) and saw the bowel consultant at the hospital. I had a colonoscopy in February but heard nothing. Neither did my GP!!! Now I've got to have a barium enema as apparently they saw nothing during the colonoscopy due to the colon being full of faeces. They said - today - that I hadnt taken the laxative and that's why, but I had! I mean SEVEN MONTHS since I saw the consultant! And my GP is mystified as he too wasn't faxed the results.I've always thought I had IBS as I've had periods of explosive poos for ages, sometimes thin ones, sometimes bitty ones, in between normal-looking ones and always suffered with loads and loads of gas and sometimes mucous. But have never seen blood on the poos before - just on loo paper infrequently. Is it possible to pass blood during bouts like these? The barium enema I'm dreading due to the pain/discomfort but it has to be done. I haven't lost weight and my appetite is good and healthy. But if it was cancer back in February it must be well advanced by now....Sorry for going on a bit but I'm so scared.
