Why Is Skin Cancer Risk Elevated at Higher Altitudes?

One of the strongest risk factors for skin cancer is direct exposure to sun. Sunlight emits ultraviolet (UV) radiation, which can damage DNA cells in our bodies. UV causes mutations DNA, and these accumulated lead cancer. Melanin a pigment present that gives its color. also helps protect against radiation sun damage.
