A member asked:
Does everyone who gets colon or rectal cancer get polyps first?
2 doctors weighed in across 2 answers
Yes: The typical colon and rectal cancers, or adenocarcinomas, start as polyps. That's precisely why getting a screening colonoscopy by age 50 is so important.

Most do.: Most colorectal cancers arise in adenomatous polyps, which are the type of polyps that are examined for and removed in colonoscopy. Data now shows that removal of colorectal polyps decreases coloretcal cancers as well as the risk of dying from a colorectal cancer. Less frequently, colorectal cancers can be founs that do not arise from polyps. This most often happens in inflammatory bowel disease.
