Precancerous conditions of the colon or rectum
Precancerous conditions of the colon or rectum are changes to cells that make them more likely to develop into cancer. These conditions are not yet cancer, but there is a higher chance these abnormal changes will become colorectal cancer.
The most common precancerous conditions of the colon or rectum are:
- hereditary colorectal syndromes
If you have a precancerous condition, you will likely have regular follow-up and screening tests to find cancer as early as possible if it develops. Some precancerous conditions can be treated with surgery to help reduce the risk that they will become cancer.
