Skin Cancer - 1,000,000 People In The Us Will Get It In 2008!

INTRODUCTION: Skin cancer represents the most commonly diagnosed malignancy, surpassing lung, breast, colorectal and prostate cancer. Skin cancer generally develops in the epidermis (the outermost layer of skin), so a tumor is usually clearly visible.

If left untreated, the disease can be very dangerous, but with early detection and medical intervention most are curable. There are three common kinds of skin cancer, of which each is named after the type of skin cell from which it arises. More than 1,000,000 people in the US will be diagnosed with skin cancer in 2008.

CAUSE: Skin cancer is an abnormal growth on the skin which can have many causes. It is often caused by exposing skin to UV rays excessively. Cancers caused by Ultraviolet exposure may be prevented by avoiding excessive exposure to sunlight or other UV sources, and wearing sun-protecting garments.

Many people go out of their way to get an artificial tan before they depart for a sunny vacation, because they want to get a "base coat" to reduce the risk of sun damage. Sunburn, due to a type of ultraviolet (UV) light known as UVB, has served as a surrogate for much more serious conditions like melanoma and basal and squamous cell carcinoma, three common types of skin cancer.

RISK: Although it is impossible to completely eliminate the possibility of skin cancer, the risk of developing such a cancer can be reduced significantly with the following steps: reducing exposure to ultraviolet (UV) radiation, especially in the early years, avoiding sunburns (NOTE: Recent studies have shown that sunscreen does not protect from melanoma). Although it is generally accepted that UV exposure is the greatest risk factor in melanoma development, some skeptics say that there is no proven data that links moderate sun exposure with the appearance of melanoma.

The possibility of developing skin cancer is also affected by where a person lives. People who live in areas that receive the most UV radiation from the sun are more likely to get skin cancer. In the United States, for example, skin cancer is more commonly found in Texas than it is in Minnesota, where the sun is not quite as strong. On a worldwide basis, the highest rates of skin cancer are found in South Africa and Australia, which are areas that receive high amounts of Ultraviolet radiation.

TYPES: The most common forms of skin cancer are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) which may be locally disfiguring but rarely metastasize (spread to other parts of the body). The most dangerous kind of skin cancer is malignant melanoma.

TREATMENT: Most skin cancers can be treated by removal of the lesion, making sure that the edges (margins) are free of the tumor cells. However,it is important that skin cancers are found and treated early because they can invade and destroy nearby tissue.

CONCLUSION: Skin cancer is the most common form of human malignancies and is also known as skin neoplasia. The use of sunscreen is recommended by medical authorities as a preventative to help protect against skin cancer (NOTE: New studies however have shown that sunscreen offers no protection from melanoma). Approximately 65 percent of melanomas and 90% of basal and squamous cell skin cancers are attributed to Utraviolet exposure. Even though it is rare, malignant melanoma is responsible for 75% of all skin cancer related death cases.

It has also been estimated that nearly half of all Americans who live to age 65 will develop skin cancer at least once. The most common warning sign of skin cancer is a change in the appearance of the skin, such as a new growth or a sore that will not heal. Most skin cancers appear after age 50, but the sun's damaging effects begin at an early age. Therefore, protection should start in childhood in order to prevent skin cancer later in life.
