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.
These types of polyps are more likely than others to become cancerous. During a screening with sigmoidoscopy or colonoscopy, polyps can be seen and removed. The type of polyp can be determined in a lab. Here is how adenomatous colon polyps are treated:1  A single polyp found during a flexible sigmoidoscopy exam will usually lead to follow-up colonoscopy to look for other polyps. 2  Then, once the colon is clean of polyps, experts recommend repeat colonoscopy every 1 to 3 years. If a person is unwilling to take the risk of developing cancer in the rectum or already has polyps in the rectum, the rectum can be removed (the risk of developing polyps in an uninvolved rectum ranges from 7.5% to 59%).
