What is Skin Cancer?
Skin cancer is the most common form of cancer. According to the American Cancer Society, almost 5.5 million skin cancers are diagnosed in the United States every year, and that number appears to be steadily rising. It is estimated that 93% to 97% of all skin cancer occurs on highly visible parts of the body such as the head, face, ears, neck, hands, and arms. It is easy to understand why this is the case, considering the fact that these parts of the body typically receive the most sun exposure. About one in five Americans will develop skin cancer in the course of a lifetime.
The areas around the eyes, on the eyelids, or near the brows are surprisingly common places for people to develop skin cancers (See Figure 2 below). According to the Skin Cancer Foundation, “skin cancers of the eyelids…account for 5% to 10% of all skin cancers [on the entire body].” Of the skin cancers that are diagnosed on the eyelids, 95% of these tumors are basal cell carcinomas or squamous cell carcinomas.”
The good news about skin cancer, in general, is that early detection of most forms (while the cancer is still in its localized stage) can mean a near 99% survival rate. The survival rate drops steadily in proportion to how deep and how far the cancer has spread at the time of detection, so regular screenings are very important.
