A new study, published in the journal Nature, looks at the ultraviolet radiation process that causes melanoma.

Researchers from the Cancer Research UK Institute and the Institute of Cancer Research found a genetic mutation that increases the risk of melanoma. However, UV exposure accelerates the development or onset of melanoma. Mutations are also triggered by ultraviolet radiation. Where sunscreen protection is used, UV exposure does not have the same adverse impact.

Unfortunately, Medical News Today points out that sunscreen alone is not enough to prevent the development of skin cancer. Researchers discovered that sunscreen failed to offer total protection from UV light. In fact, radiation still caused genetic abnormalities, just at a lower rate.

This research demonstrates, nonetheless, sunscreen has its role in skin and overall health. However, it also warns not to rely  cannot rely solely on sunscreen to protect the skin. Good sun safety habits are important, including taking care not to burn. Sunburns are a clear sign that the DNA in skin cells has been damaged. Over time, this can lead to skin cancer.

As well as applying generous amounts of at least 30 SPF sunscreen when in the sun, the National Council on Skin Cancer Prevention recommends other sun safety habits. This includes seeking shade when the sun is at its strongest and wearing sun-protective clothing, such as a wide-brimmed hat, wrap-on sunglasses and a T-shirt.
