Forgot to mention most important tidbit I learned. Normally, you need to have your first colonoscopy at the age of 50. Mo matter if you have symptoms or not. But for certain ethnic groups, the probability is much higher. Your doctor may, or may not, tell you this (political correctness? Illiteracy? Not sure. In my case, family doctor was in denial even when he saw it), you need to do your own research. Find out where you belong, you may need it at age 30.
