There is a very slight elevated lifetime risk of developing lymphoma in the small bowel with Crohns patients -- most likely from the extended effects of inflammation there. Small bowel lymphoma is a very rare condition for all people and it is still very rare for Crohnies -- something on the order of 1 in tens of thousands I think. Unfortunately its symptoms are minimal and resember standard Crohns symptoms until the cancer is well advanced. The two tests to detect it are the SBFT barium tracking X-rays and the capsule endoscopy, but again, the incidence is so low that I don't think any GIs would encuorage regular screening. Basically we all have much higher chances of developing one of the other more common cancers (breast for women, prostate for me and of course colon, which should be screened for in our regular scopes.) You are probably also more likely to be hit by a bus than to develop small bowel lymphoma. The only area of increased concern is a slight uptick in cases among patients on biologics, and especially biologics with immunosuppressant therapy, but the incidence remains very low there. Bottom line is it is very unlikely that you will get this.
