The Melanoma Risk Assessment Tool (MRAT) is a calculator developed for use by health professionals to estimate a patient's absolute risk of developing melanoma. Absolute risk is the likelihood that a person will develop a specific type of cancer over a certain period of time, in this case five years.
Although an individual's risk may be accurately estimated, these predictions cannot precisely determine who will develop melanoma. If you are not a health professional, you are strongly encouraged to discuss your results and personal risk of melanoma with your provider.
This calculator takes about five minutes to complete.
About the Calculator
The Melanoma Risk Assessment Tool was developed using data from a large case-control study in the United States. Risks for this skin cancer are estimated for non-Hispanic White individuals only between 20 and 70 years of age. Data on individuals from other racial and/or ethnic groups are too limited to accurately estimate risk.
Calculator Limitations
Patients who have had one of the following diagnoses should be in screening and surveillance for melanoma and should not use this calculator to estimate their risk:
- Melanoma
- Melanoma-in-situ
- Non-melanoma skin cancer
- Family history of melanoma
