Coffee impacts melanoma development

If you need a cup of coffee in the mornings to wake you from your slumber, here’s some good news for you. Your morning café au lait routine could help ward off melanoma, skin cancer. A study conducted by the National Institutes of Health (NIH) and Yale School of Public Health, followed 4,47,357 non-Hispanic white participants over 10.5 years to determine the degree to which their coffee intake affected their risk of melanoma.

The study started with a ‘food-frequency survey’. The results demonstrated that 2,905 participants developed melanoma over the study period. The research saw a direct link between coffee intake and melanoma. Participants who drank four cups a day, reduced their chances of developing melanoma by 20%.

It was found that only caffeinated-coffee had an effect on melanoma, whereas its decaffeinated counterpart had no effect. Interestingly, caffeine has been shown to be an absorbent of ultraviolet radiation, working like a sunscreen, when consumed both orally or applied externally.

The study indicated that bioactive compounds in coffee quash UVB-triggered skin cancer, by shielding the body from oxidative stress and DNA damage in cells. It also keeps the swelling in epidermal cells, in check. The results factored in the participants’ age, sex, alcohol intake, smoking habits, body mass index (BMI) and ultraviolet (UV) radiation exposure.

This study reveals one of the many benefits of coffee. Increasing your coffee consumption can be a preventive measure towards the development of malignant melanoma, past the in situ stage. In situ melanoma is a condition where the cells have not reached beyond the outer layers of the skin. So change up your morning routine with a cup of coffee.
