Colon Cancer/IBD patient colon cancer screening


I have had Ulcerative Colitis since 2003, and currently I am 29 years old.  I was wondering how long after being diagnosed should I begin getting regular colonoscopies to screen for cancer?  I've heard anywhere between 8 and 15 years or more, but i've also heard that it depends on the severity of the disease.  I've heard that if the disease is "left-sided" (which in my case it is) that my risk for cancer isn't much higher than normal people.  My last colonoscopy was in 2005 and since then I've only had a couple of brief minor flare ups; most of the time i've been in full remission, not sure if remission improves cancer risk, I'm currently in remission and not taking any meds.

so it's been 6 years since my last colonoscopy, and 11 years since diagnosis. Should I be scheduling an appointment for a colonoscopy soon? can it wait a year or two?

thank you!

If I happened to be you I would have my colon checked soonest to be on the safe side. You should then discuss with your gastro-enterologist when to have the next check. P.S. I have a colonoscopy once EVERY year. I'm soon 69, colon cancers are rather common in my age group and I have already had prostate cancer (radiation treated). I do not want any more nasty surprises and my rectum & colon had a rather high radiation dose too. Good luck!
