Skin cancer is a disease that seems to be more common with each passing day. This may be because more research is done on the disease and people have become far more aware of skin cancer now. Or maybe people are getting skin cancer more than they used to because of environmental conditions like the increase in ultraviolet radiation from the sun due to holes in the ozone layer. So what is behind this increase ? This article will discuss what causes skin cancer. The most likely way a person will get skin cancer is by being exposed to sunlight for too long. Do you remember when having a suntan was a sign of health and people used fake tans or sun beds to keep that healthy glow throughout the year ? Well this thinking has largely fallen away now (or at least it should be falling away). You will find in regions in the world where the sun is particularly strong the idea of sun baking yourself every day has been replaced with the need to wear a shirt, hat, eye protection and a 30+ sun protection factor sunscreen. The fact is that, although everyone wants to spend a bit of time in the sun once in a while, too much sun on the skin will lead to skin cancer. How much sun is too much is largely down to the individuals skin type. People that burn easily in the sun are more at risk to getting skin cancer. This is intuitive as burned skin is painful and pain is the body's warning sign that something is wrong. However people will often ignore signs like this out of vanity or stubbornness. Or maybe they work in environments that are harsh. People that burn easily are people that have less melanin. Melanin is the substance found in the skin, hair and eyes and is responsible for producing pigmentation or color. People with less melanin will have fairer skin, red or blond hair and lighter colored irises. The most pronounced case of deficiency of melanin is known as Albinism. Albinos have little or no color in their skin, hair and eyes. Melanin, in effect, protects the skin from skin cancer and melanoma by darkening it. This helps it resist sun burn which is an outward sign of over exposure to sunlight. A lack of melanin leaves a person open to ultra violet radiation from the sun. This is the case with albinos who must be extremely careful in the sun. Being exposed to Ultraviolet radiation is another cause of skin cancer. This may happen in a work environment but is most common in the humble sun bed. The sun bed is a popular way to get a tan all year round but overuse of the bed puts your skin at risk to damage and ultimately skin cancer. To finish, exposure to UV radiation will cause skin cancer. You should take action to avoid being exposed to UV radiation, most commonly by being exposed to the sun. At all times, when in the sun you should wear a hat, clothing to protect your body, sunglasses and sunscreen on areas of the body that are nor concealed like the face.
