What is my risk factor?
The following chart gives the relative risk of a number of factors. For example if you have dysplastic naevi, previously had a melanoma or have a family history of melanoma then your personal risk of melanoma increases by a factor of between 121 to 1138 times the averge risk. The average life-time risk of a male born, raised and lived all his life in Queensland is one in 15 so multiplying that risk by 100 times is significant. Females have a 1:20 risk of lifetime melanoma.
