Causes of Skin Cancer


By adam eric at 2011-01-28 03:09:02
The causes of other types of cancers are totally unknown. But the cause of skin cancer can be detected easily. People who are continuously exposed to the harmful radioactive substances or harmful ultraviolet or infrared rays are prone to skin cancer easily. Usually the workers who continuously work in polluted environment damage the quality of their skin within a shorter period of time.

this is the suppression of the immune system, which is our bodies means of protecting itself from harmful foreign matter like germs or substances that cause an allergic reaction. Our immune system can become suppressed due to some diseases like HIV or it can also be due to medications to combat or resist autoimmune diseases or prevent the rejection of an organ transplant. The body is now weakened to fight infections.

The primary or number on cause of skin cancer is UV exposure or sun exposure. The sun creates powerful radiation rays that can damage the skin over time. Contrary to what you might have heard about needing to have been sunburned to develop skin malignancies, this is only part of the story. You don't need to have ever been sunburned during your life to develop this type of cancer.

The Sun produces two forms of ultraviolet radiation that is thought to be the carcinogen that causes cancer. These are UVA and UVB radiation. They are both ultra violet radiation but have different wavelengths. Initially it was though that UVA was the only cause but recent research suggests that UVB is just as bad.

Skin cancer is a very real risk for folks over 50 years old and it is a lot more common than you might think. There is more than one type of skin cancer to be on alert for and all skin cancers must be taken seriously and treated as soon as possible. Although everyone is at risk of skin cancer those who fair or light skinned have much more risk of skin cancer.

the two associated with skin cancer are UVA (ultra-violet A) and UVB (ultra-violet B) rays. UVB rays are the shorter-wave solar rays and are more unlikely to cause skin reddening and sunburn. UVA rays, however, would have more permanent damages to the skin as they penetrate much deeper to the skin.

Though there are three common form of skin cancer; the Basal cell carcinoma, Squamous cell carcinoma and Melanoma, the first two are not very serious and can be treated and cured easily. The third type, Melanoma, the cancer of the melanocyte is the most severe of the lot and causes the most number of skin cancer associated death around the world.

So really, what causes skin cancer? The answer is simple, too much exposure to the sun. Sunburn, cumulative tanning, artificial ultraviolet rays produced by tanning beds all can be a prerequisite to cancer of the skin. Enough is enough! At the very least these practices are damaging your skin, causing premature aging and wrinkles.

on the skin bumps develop in the form of a circle and the bumps are usually in the shape of a pear. If they swell then immediately visit should be made with the doctor. These bumps usually occur in the areas that are often exposed such as face, neck or shoulders.

Experts say that alcohol is the second largest risk factor for oral cancer. While exactly how alcohol functions is unexplained, there are theories. It is believed that the liver damage brought on my alcohol causes cellular changes. These cellular changes may lead to modifications in the tissues of the mouth and throat.
