What % can colon cancer return with ulcerative colitis after cancer tumor is removed from that part of colon ?

Cancer recurrance: Cancer can recur unfortunately. Recurrence rates vary. Monitoring with your cancer team is the best way to manage this issue. Monitoring programs are also known to improve overall health, as new health issues get diagnosed and treated sooner. A pet scan, colonoscopy and blood tests are the basis of colon cancer monitoring. Okay to ask your regular doc and cancer team about monitoring.

It varies by stage: The risk of recurrence in patients with ulcerative colitis is somewhat higher. But it all depends on the stage of colon cancer when it was removed. If it had not spread into the lymph nodes(stage-3), then the prognosis is fairly good. Ask your doctor this question and get an answer which is dependent on the stage of colon cancer you had.

High risk of cancer: Recurrence risk given cancer is a function of the stage of cancer when diagnosed, independent of uc. However, uc patients have an approximately 1% per year risk of new cancer appearing. Because of this high risk, total colectomy has been the standard of care for uc. If you have any colon left, it should be examined and biopsied periodically looking for dysplasia, the precursor of cancerous change.
