How long for colorectal cancer to develop? If polyps aren’t removed and they keep growing, how long does it take before they turn into cancer?

In brief: Years usually

There are different types of polyps and some are more aggressive than others.
But usually these take years (2-5 years, some will say 10 years) to grow to cancer. There are more aggressive types that can develop in a year or less but fortunately they are the rarity.

In brief: All

All have to do with the risk factor for colon cancer.
The most aceppted theory, it is for a simple polyp to become a cancer can take 10 years but they are many types of polyps and they can become cancer faster.
