confused  I recently had a colonoscopy and my dr removed a adenomatous polyp.  He said the area around it was biopsied and came back fine, but that we have to keep a much closer eye on my colon, since peole with crohns have an increased cancer risk.  Now i am so worried about the future.  Has anyone else had this type of polyp (pre-cancerous) and do you have information for me?  Does anyone have any info on increased cancer rates and crohns?  Any help appreciated!

Hasn't happened to me yet, but those polyps commonly progress to cancer. They are more common in celiac disease. Crohn's cancer rates are skewed by some of the meds that they use which are known to cause cancer. And then there's the malabsorption problem which causes its own problems. You might want to try eliminating gluten as a precaution - in case there is a hidden celiac disease involved.

I had three polyps removed during my last colonoscopy. I had a colonoscopy 3 years prior and no polyps were seen at that time. My age places me in the segment of the population where polyps are more likely to form. Two of my polyps were of the adenomatous type. My GI said that it is now necessary to have a colonoscopy at least every 3 years if not sooner. I am not really worried about them finding a pre-cancerous type polyp. I just know now I must be vigilant about getting my colonoscopies. There is some good info about adenomatous polyps here:

Thanks for th info!  I'm surprised that only a couple of people have had to deal with this.  I thought it would be more common.  It is still very scary to me.

As I understand it, precancerous polyps and Crohns are separate and distinct issues related to cancer. Many people with no inflammatory bowel condition have polyps which require regular scopes and removal to prevent them progressing to cancer. There is a slight elevated risk of developing bowel cancer due to chronic inflammation and tissue damage from Crohns, especially if the inflammation is in the colon; those with less colon involvement and more in the smal bowel are thought to be at considerably less cancer risk. And as noted there have been some very slight increases in smal bowel lymphomas in Crohns patients, again probably from chronic inflammation and perhaps some immunosuppressant meds. Overall though the cancer risk directly related to Crohns is somewhat less than for ulcerative colitiis, and it is still rather minimal. As long as we have regular scopes after 15-20 years of actiev disease, with biopsies of inflamed or ulcerated areas to check for early cell dysplasia (a sign of possible advancing to cancer) we are probably at even lower risk of dying from colon cancer than the general population, people who do not routinely have scopes.
