Human beings everywhere share a special relationship with the sun. We are warmed by the sun and our earth sustains and enriches itself with the help of its glimmering rays. However, as we crave the sun's heat and light, this golden star can have a dangerous and deadly effect upon us. We must be aware that there is a dark side to the sun and learn how to protect ourselves from it. Our health, well being, and livelihoods depend on it.

AGRICULTURAL WORKERS ARE AT RISK:
The sun sheds invisible ultraviolet rays which can be extremely dangerous to the skin and are responsible for sunburn, premature aging and other types of skin damage including cancer. Agricultural workers top the list of candidates for skin cancer because they are outdoors and are exposed to the sun on a daily basis. They also, probably more than any other group of workers, share a legacy of respect for the forces of nature and the knowledge to best co-exist with these elements.
Like any other part of our bodies, skin is a place where cancer can develop. Fortunately, most skin cancer can be cured when discovered early and treated promptly. If you know the facts about skin cancer, you know that it can be prevented.
Skin cancer is linked to excessive sun exposure. According to the American Cancer Society, 600,000 cases of skin cancer occur every year in the United States. Out of the 600,000 cases, an estimated 8,200 end in death.
When exposed to the sun, our skin can go through a series of changes:

Short Term Effects Suntan: A suntan is not a sign of good health. As a defense mechanism, the body produces a pigment called melanin, which turns the skin brown. Suntanning causes skin to age prematurely.

Sunburn: Sunburns occur when the body receives excessive amounts of radiation (the full effect of the sun is not realized until 14 to 24 hours later). Along with a sunburn, the skin may blister, which indicates a second degree burn.

Delayed Effects Skin changes: Skin can change in several ways. The sun can cause skin to age, wrinkle, thicken, dry out, freckle, and blemish, and develop a rough texture.

Skin Cancers: Skin cancers are caused by excessive exposure to the sun's ultra-violet rays. It is important to remember that sunburns are not the only condition that lead to the development of skin cancer.
TYPES OF SKIN CANCER
There are three basic types of skin cancer: Basal-cell carcinoma, Squamous-cell carcinoma and Melanoma. The first two types are very common and easily curable,
