I have had crohns for 10 years now. Very uneventful up until about 3 months ago! Found out I had a fistula between my bladder and small intestines! Started Humira was doing well... went to the dermatoligist. Had a mole removed. Came back inconclusive for Melanoma! Now my GI doc wants me to stop the Humira and have surgery all because they can not tell me what is going on with my leg. Cancer or not. I have strange cells and they don't know what they are. the Melanoma thing doesn't freak me out as much as having surgery! Just don't know what to expect! Scared. Do most surgeries end up with stomas? If my second test on my mole comes back negative for melanoma, should I still do the surgery or try another drug to treat my Crohns?
