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.
Depending on the size and number of polyps, you may need to follow a more rigorous screening schedule in the future. If your doctor finds one or two polyps less than 0.4 inch (1 centimeter) in diameter, a repeat colonoscopy in five to 10 years may be adequate, depending on your other risk factors for colon cancer. colonoscopy is considered negative if the doctor doesn't find any abnormalities in the colon. If you're at average risk of colon cancer â you have no colon cancer risk factors other than age â your doctor may recommend waiting 10 years and then repeating the exam if your colon preparation was adequate.
