Researchers have found that the number of freckles on the coloured iris of the eye is a strong indictor of your risk for melanoma.
They found 3 or more iris ‘freckles’ were associated with a 45% increased risk of melanoma. The associated risk was particularly seen in participants under 40 and reflected a possible genetic susceptibility for melanoma.
Melanoma is the most common cancer for young Australians aged 15-39 years old. Melanoma risk is usually calculated using sun damage, skin type, eye colour, personal / family history of skin cancer and the total number of naevi. Assessing the number of naevi and freckles on the iris may become another useful tool used for the prevention and management of melanoma.
