I had an internal hemmrhoid but was advised to have the colonoscopy because my paternal grandmother died of colon
cancer years ago. They found a 5mm adenomous type polyp
and said I need to be rececked in 3 years. My questions are: aren't I too young for this type of precancerous polyp given I eat healthy, not obese, etc and my second question and probably most important is that 6 years ago I had a colonoscopy (rectal bleedng) and it was clear. Did this 5 mm polyp grow in just 6 years?
