My doctor told me after having the decease for 10 or more years, they want to scope, flaring or not to take biopsies and check for cancer since he said after 10 years, the risk of cancer goes even higher. Since I've had crohns for 12 years, I'll be doing it every 2 years now, sooner if something goes wrong. Hopefully nothing will, and since I just had one 2 weeks ago, I will hopefully be good for another couple of years!!
