What is the most common risk factor for skin cancer and how can we protect ourselves from skin cancer?Risk Factors for Skin CancerThe most common risk factor for skin cancer is exposure to sunlight, which is a source of UV radiation. The sun’s rays cause skin damages, which can lead to skin cancer. Individuals can protect themselves from skin cancer by avoiding outdoor activities when the sun’s rays are strong usually during the middle of the day.

The rays can go through windows, clouds, windshields, and light clothing. We should also wear long pants, long sleeves, and particularly tightly woven fabrics. People should also wear sunglasses that absorb UV radiation to protect the skin area around the eyes. It is also advisable to wear wide brim hats that shade the neck and face.3.

Blisters develop and the appearance of the skin changes to a reddened, splotchy appearance.

There is severe pain and swelling in the second degree burns.Third Degree BurnsThis is the most severe skin burn and it involves all layers of the skin. Third degree burn may affect muscle, fat and even bones. The burned areas may appear dry and white or may be charred black. Difficulties in exhaling or inhaling and carbon monoxide poisoning may occur if a third degree burn victim inhales smoke.4. What are the two major risk factors associated with burns?
