Dear Sue. You are not just suffering from diverticular disease
but also polyposis of the colon, a condition in which multiple polyps form in the colon and sometimes in the small bowel. Some of these polyps may with time develop cancer. Your having pain and weight loss
are not good signs and more in favour of cancer development. I am assuming that the polyps that have been removed previously were sent for biopsy
and that none of them showed cancer. I would advise you to first undergo a contrast enhanced CT scan
of the abdomen. That will give us a fair idea of what we are dealing with and if there is any evidence of cancer development. Also, a colonoscopy
is advisable (before the CT) but only by an experienced gastroenterologist in whose hands it shouldnt be a problem.
