Precancer vs cancer

What’s the difference between precancer and cancer?

Before colon cancer develops, an abnormal growth called a polyp usually develops on the inner lining of the large intestine or rectum. Polyps are common and begin as noncancerous growths, but some can turn into cancer over time.

The earlier colon cancer is found, the easier it is to treat. This is why regular screening is worthwhile—it has the potential to save lives.
