Melanoma Risk Calculator

This is the Melanoma Risk Calculator originally peer-reviewed by the Journal of Clinical Oncology.  For the newest version of this research tool, please visit

An interactive tool designed by scientists at the National Cancer Institute (NCI), the University of Pennsylvania, and the University of California, San Francisco to estimate a person's absolute risk of developing invasive melanoma. The tool helps clinicians identify individuals at higher risk of melanoma and plan with them for appropriate screening interventions.

Before using the tool, please note the following:
  • The melanoma risk calculator was designed for use by health professionals. If you are not a health professional, you are encouraged to discuss the results and your personal risk of melanoma with your doctor.

  • The tool should not be used to estimate melanoma risk for people who have already had a diagnosis of melanoma, melanoma-in-situ, non-melanoma skin cancer, or a family history of melanoma. These individuals should be in screening and surveillance programs.

  • This tool was developed using data from a large case-control study in the United States. The risks are estimated only for non-Hispanic whites; data on other ethnicities were too limited to accurately estimate risk.

  • A recent version of Internet Explorer, Firefox, or Netscape is recommended.

We welcome use by other groups to test the model.
