Skin Cancer

Skin cancer is the most common form of cancer in the United States and generally tropical such as in Indonesia, Brazil and African country. In United States more than 600,000 cases diagnosed annually. The most common types of skin cancer are the highly curable basal-cell or squamous-cell cancers. The most serious skin cancer is melanoma, which causes more than 6,000 deaths each year. Factors that increase the risk of developing skin cancer include excessive expose to the Sun's ultraviolet rays, a fair complexion, or occupational exposure to coal tar, pitch or radium.

A change in a mole or other spot on the skin may be the first sign of an early malignant melanoma or other form of skin cancer. Regular self-examination to detect changes in asymmetry, border, color, and diameter of a mole is the best way to detect a problem while it is still treatable.

A common benign mole is usually round and symmetrical, with smooth, even borders (top left). A persistence reddish patch or irritated area on the arms, legs, or shoulders may be a sign of basal-cell carcinoma (top right). Some forms of early malignant melanoma have an asymmetrical shape (bottom left) or an uneven border with notched or scalloped edges (bottom right).

The form of skin cancer that is sometimes to be avoided is warts or a nibble, abnormal moles and abnormal pimple or acne. If you have this abnormal sign on your skin you must check this condition to the doctor to make sure that those conditions are not including to dangerous cancer.
