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.
Polyps in the colon can vary in size and number. 1  Hyperplastic polyps are harmless and do not develop into cancer.  Adenomatous polyps are the most common. Although most will never develop into cancer, they do have the potential to develop into colon cancer.
