Skin Cancer

Gone are the days when people sent children outside to play to get a little
color in their cheeks.  They know too much about the dangers of unprotected
sun exposure and the threat of skin cancer.  Or do they?  Despite the fact
that 58% of parents remembered hearing about the importance of protecting
their children from the sun, children are still playing in the sun without
sunscreen or protective clothing (3., p 1).  Sunburn is the most preventable
risk factor of skin cancer.  Skin type and family history cannot be changed.
Protection from the sun and education of the potential hazards of the sun
need serious attention.  The American Cancer Society estimates that
over 850,000 cases of skin cancer will occur in the United States during 1996.
Of those cases, they predict that 9,430 will end in death (4., p 1).
Apparently, Americans still do not have an adequate amount of prevention
information to help reduce the disfigurement and mortality from this cancer.

Exposure to the ultraviolet radiation from the sun is the most frequently
blamed source of skin cancer.  Due to the reduction of ozone in the
earth’s atmosphere, UV radiation is higher today than it was several years
ago.  Ozone serves as a filter to screen out and reduce the UV light that
reaches the earth’s surface and its people.  Very simply, sunburn and UV light can damage the skin and lead to skin cancer (1., p 1).  The American Cancer Society also faulted repeated exposure to x-rays, artificial forms of UV radiation like tanning beds, and contact with chemicals like coal tar and arsenic as other causes of skin cancer (4., p 1).  Additionally, if there is a history of skin cancer in the family, an individual may be at a higher risk (1., p 1).  Individuals who have experienced only one serious sunburn have increased their risk of skin cancer by as much as 50% (1., p 4).

There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and malignant melanoma.  Basal cell carcinoma usually imposes itself on areas of the skin that have been exposed to the sun.  It usually appears as a small raised bump with a smooth shiny surface.  Another type resembles a scar that is firm to the touch.  Although this specific type of skin cancer may spread to tissue directly surrounding the cancer area, it usually does not spread to other areas of the body (9., pp 2-3).

Squamous cell carcinoma growths also appear most frequently on areas of  the body that have been exposed to th...
