The sun and the skin

R StC Barnetson

People with darkly pigmented skin very rarely get skin cancer. Those of a Celtic constitution, when exposed to strong sunlight in countries such as Australia, get skin cancer very readily. Australia has the highest incidence of skin cancer in the world, with 140 000 new cases per year, and 1200 deaths per year, mainly from melanoma.

It is therefore important to understand that there is a variation in skin sensitivity to sunlight. This is rated from one to six (Fitzpatrick classification). Skin type one subjects have red hair and do not tan, burn very easily in the sun and develop skin cancer readily, whereas skin type six subjects have black skin (with an inbuilt sun protection factor of 10) and very rarely develop skin cancer. This is a useful guide in assessing the risk of sun damage and in determining the dose of ultraviolet B in treatment.
