Skin Cancer
Causes and Risk Factors - What Causes Skin Cancer?
There are three types of UV radiation: A, B, and C. All three are
dangerous and able to penetrate skin cells. UVA is the most common
on earth, and is harmful to the skin. UVB is less common because
some of it is absorbed by the ozone layer. It is less harmful than
UVA, but can still cause damage. UVC is the least dangerous because
although it can cause the most damage to the skin, almost all of
the UVC rays are absorbed by the ozone layer.
