No      Yes

Terms and Conditions

To use this melanoma risk calculator you must agree with the following terms and conditions of use.
  1. This risk assessment tool aims to give an estimation of your risk of developing a melanoma over the next 5 years.
  2. The calculator is not intended to be used as a substitute for an independent health professional's advice.
  3. This calculator has been based on the work of the Victorian Melanoma Services with some additions and adjustments by the present author. The limitations of the original calculator and of any addition/adjustments are due to the incomplete nature of the underlying medical evidence and its validity to an Australian population. Please note that while most of the calculator is based on available medical evidence, this evidence is incomplete and constantly evolving. This calculator can only be used as a general guideline and not as an absolute predictor of your personal risk of skin cancer.
  4. It is highly recommended that you discuss your personal risk factors and results of your risk assessment with your doctor.
  5. If you have a dark skin type (Asian, dark Aboriginal / Torres Strait Islander or African Skin) then this calculator is unsuitable for you as there is insufficient medical data to base calculations on. However, with such a skin type your risk of Melanoma skin cancer is very low.
I have read and understood the information above.

Acknowledgements and Limitations

This risk calculator is based on "Emily's risk assessment tool", written by Researcher's, Physicians and other employees of the Victorian Melanoma Service (VMS, The Alfred Hospital, Commercial Rd Prahran. We gratefully acknowledge their work.

Please note that the research that this calculator has been based on is not complete and that our knowledge of melanoma skin cancer is continuously evolving. Furthermore the doctors at the Skin and Mole Clinic have added in some questions of our own which we feel are of importance. These do not have a formal research base of knowledge to base risk values on. Please do not use this calculator in place of a medical skin check.
