Colorectal Cancer Risk Assessment Calculator - NCI

Personalized Risk of Developing Colorectal Cancer

  • While a patient's risk may be accurately estimated, these predictions do not allow one to say precisely which patient will develop colorectal cancer.
  • Some patients who do not develop colorectal cancer have higher risk estimates than patients who do develop colorectal cancer.
  • As a reminder, this tool was designed for use by health professionals. If you are not a health professional, you are encouraged to print these results and discuss them with your health care provider.
  • The tool uses a patient's medical history and the history of colorectal cancer among their first-degree relatives (father, mother, sisters, brothers, sons, daughters) to estimate absolute colorectal cancer risk—the chance or probability of developing colorectal cancer over a defined time period.
