Good morning Sorry to hear about your illhealth The findings that described in the mid descending colon are suspicious. Cancers usually arise from colonic polyps with look like outward growths with or without peduncle. And whether it is really cancer or not only a biopsy and histologic examination (in the pathology lab) will confirm it Patients who are suffering from crohn s disease for a long time are at increased risk of cancer in the colon and intestines and so periodic surveillance colonoscopies are recommended. I would also like look at your medication list for crohn s disease. I would liek to bring to your attention that many newer biological therapies have come in last decade and a half which have actually prevented repeat surgeries to certain extent. I would like you to check with your physician about them I am sure that your physician is also taking care of your diverticular disease I hope I answered your question I would be happy to hear from you again in case of any further queries Wish you a speedy recovery
