New research published in the American Journal of Epidemiology has found no association between skin color and skin cancer risk.
The study, which used data from more than 5,500 individuals from the US Centers for Disease Control and Prevention (CDC) and US Food and Drug Administration (FDA), found no link whatsoever between skin colour and cancer risk, and the study did not identify a clear reason why people with darker skin might be more at risk for melanoma.
The authors note that “even after adjusting for potential confounders, we found no significant associations between skin melanin levels and melanoma risk.”
The study authors note, “Despite the absence of a clear cause-and-effect relationship, we acknowledge that it is possible that people with greater melanin content might be at greater risk for skin cancer, and that this might explain why the risk of melanoma has increased over the past several decades.”
They note that the results do not support the idea that “black skin color has a protective effect against melanoma,” which is the term used by some skin cancer researchers to refer to the condition.
Instead, the authors suggest that it might be possible that melanoma “may be more common among darker skinned individuals, because they are more likely to experience a variety of adverse medical and psychological conditions that may contribute to skin cancer,” such as depression, anxiety, and stress.
“The study’s finding that melanin does not predict melanoma should be taken with a grain of salt,” the authors write.
“We know that melanocytes are highly susceptible to damage and that it takes a lot of damage to make melanocytes senescent, so we should be cautious about extrapolating melanoma prevalence estimates to the population of people with lighter skin.”
As previously reported, melanoma is a rare, aggressive, and aggressive cancer that usually develops in people between the ages of 20 and 50.
However, skin cancer is also the third most common cause of death in the US, after cancer of the lung and heart.
As the CDC reported in a press release on the study, melanomas are most commonly found in black Americans, and melanomas in non-Hispanic whites are nearly twice as common as those in Hispanics.
“It is a serious disease that requires timely and aggressive treatment,” Dr. Robert M. Clements, MD, MPH, director of the UCLA National Institute of Allergy and Infectious Diseases, said in a statement.
“It’s important that melanomas be recognized as a disease that needs urgent attention and that our patients be protected from them.”
