A million skin cancer cases are diagnosed annually in the US. While the sunlight is a main risk factor, to avoid the sun generally is not actually a viable option.
The sun provides humans with heat and makes life possible on the Earth. The sun rays make our bodies produce vitamin D neccessary for sustaining life. Various activities outside the house are very useful as exercise and that is of great importance for our health.

The index of UV is a huge factor as well. It offers a kind of guideline to the sun danger level. The index asseses the UV amount that reaches the Earth at some particular time. And the higher the amount, the facter the skin damage can happen. This means that the higher the index of UV the faster the damage is.
No matter the different types of skin UV rays damage skin of every human being. It is important to remember that fairer skin can burn facter, this can lead to quicker skin damage particularly if the skin is unprotected. Among other risk conditions we can mention a melanoma history, freckles, individuals living at high altitudes are more predisposed to this disease.
