Detailed explanation-1: -Too much UV radiation from the sun or sunbeds can damage the DNA in our skin cells. DNA tells our cells how to function. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.
Detailed explanation-2: -The depletion of the ozone layer leads, on the average, to an increase in ground-level ultraviolet radiation, because ozone is an effective absorber of ultraviolet radiation.
Detailed explanation-3: -Risk factors Excess exposure to UV radiation from sunlight or use of indoor tanning also increases risk for all skin cancer types, as does a personal history of the disease.
Detailed explanation-4: -UVB is thought to be the main cause of skin cancer overall, but it is not yet known whether UVA also plays a role in causing melanoma. Artificial sources of light, such as sunlamps and tanning beds, also increase your risk of developing skin cancer.
