Skin cancer 'more deadly in non-white population'28 July 2006 People with darker skin are more likely to die from skin cancer and related complications than those with paler skin, according to new research. The study presented at the American Academy of Dermatology in San Diego, California, claims that, although dark-skinned people are less likely to develop skin cancer, when they do it is typically more "aggressive" and is often diagnosed only in its later stages, meaning fatality rates from the disease are higher. People with darker skin have more melanin in their skin cells. This gives the skin a darker colour and also blocks out harmful ultraviolet (UV) rays from the sun, meaning people with darker skin are less susceptible to severe sunburn and skin damage. However, scientists at the University of Cincinnati, Ohio, point out that dark-skinned people can still develop skin cancer and suffer disproportionately higher rates of death as cases are often not diagnosed until the last moment. "There's a perception that people with darker skin don't have to worry about skin cancer, but that's not true," explains Dr Hugh Gloster, lead author of the study. The team studied 50 years' worth of data from medical centres across the US, Asia and Africa, finding that melanoma, the second most common form of skin cancer, appears to develop differently in people with darker skin compared to white people. The study claims that UV radiation, which is a significant cause of melanoma in people with paler skin, is not such a risk factor in dark-skinned people as the disease usually appears on the palms of the hands, soles of the feet and under the nails - areas normally protected from the sun.
