Last year I was experiencing severe diarreah and going to the bathroom anywhere from 5-10 times a day consistently. I made an appointment with a gastroenternoligist and he said he wanted to do a colonoscopy. I got the colonoscopy done at age 27 and it came back without have Colitis or Chrons disease but he did find a 7mm polyp near my rectum. When i went for my follow up he told me that the polyp was precancerous and if i did not come if for my systems which were not related to the polyp, the polyp would have turned into cancer in 2-3 years. This week I just had another colonoscopy and he found a small polyp and removed it. This still has to be tested.
I am very concerned that I am so young and keep getting these polyps. Does this mean I will get colon cancer? Any suggestions of tests I should have my doctor do? I am only 28 and everywhere I look it seems most people do not have issues until their fifties. Any suggestions or advice how to proceed is greatly appreciated.

Thank you!
