Normally a colon cancer can take from 7 to 10 years to develop from a polyp. That is why the recommendation for colonoscopy is every 10 years, unless there is a prior family history. However, with Lynch Syndrome (HNPCC) due to a genetic mutation a colon cancer can develop in as little as 1 to 2 years.
Colon polyps are growths on the surface of the colon or large intestine. There are three types of colon polyps. One type, adenomas, have the greatest risk of turning into pre-cancer or colon cancer. About 10% of people get this type. About 90% of people get another type of colon polyp called hyperplastic polyp. Some risk factors for colon polyps include age, family history, and diet.
