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.
Adenomatous polyps, or adenomas, are polyps that grow on the lining of the colon and which carry a high risk of cancer. The adenomatous polyp is considered pre-malignant, i.e., likely to develop into colon cancer. The other types of polyps that can occur in the colon are the hyperplastic and inflammatory polyps.They are unlikely to develop into colorectal cancer. About 5% of people aged 60 will have at least one adenomatous polyp of 1 cm diameter or greater. polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated. If no stalk is present, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, sinus(es) , urinary bladder and uterus.
