[|Human|] Six months ago I had a routine colonoscopy at age 49. The Doctor said I had an ulcer in the ilium. Biopsy was negative. This week I had a followup colonoscopy and the Doctor said more ulcers had appeared (awaiting biopsy results). What are likely causes, what is the risk of cancer?
[|AI|]  Hi, dear I have gone through your question. I can understand your concern. There are many causes of multiple ulcers.  It may be due to Crohn's disease, ulcerative colitis, typhoid, tuberculosis, amoebic colitis or colorectal cancer.  Biopsy gives you exact diagnosis.  It is negative for cancer, so you should search for other cause and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
