Although there are numerous types of cancer, the definition is the same - a growth caused by abnormal and uncontrolled cell division. According to the Centers for Disease Control and Prevention (CDC), skin cancer is the most common form of cancer in the United States.

The skin is the largest organ of our body. Although it's delicate, our skin works hard to combat the elements working against it.
Skin cancer forms in the tissues of the dermis and there are several types. The most common forms of skin cancer are basal cell and squamous cell cancer. Although these cancers are serious, the most dangerous form of skin cancer is melanoma.
Each year, 70,000 Americans are diagnosed with melanoma skin cancer.
Melanoma skin cancer
This skin cancer forms in melanocytes (skin cells that make pigment) and can occur on any skin surface. In men, it's often found on the head, neck, or back. In women, it's often found on the lower legs or back.
Basal cell skin cancer
This skin cancer forms in the lower part of the epidermis (the outer layer of the skin) and is typically found in areas exposed to the sun. It's commonly found on the face and is the most common type of skin cancer among people with fair skin.
Squamous cell cancer
This skin cancer forms on squamous cells (flat cells that form the surface of the skin). It's usually found in places that are not exposed to the sun, such as legs or feet and is the most common type of skin cancer among people with dark skin.
Looking at Numbers
In a recent study by the American Cancer Society, the overall number of cancer incidences and death rates has decreased. However, in the past 30 years melanoma cancer incidents have increased rapidly. Most recently the increases have occurred among young white women between the ages of 15 - 39 years (3% per year since 1992) and white adults 65 years and older (5% per year for men since 1985 and 4% per year for women). Melanoma skin cancer primarily affects white adults and the occurrence rate for whites is ten time higher than in blacks. Among whites, rates are more than 50% higher in men than in women.
Melanoma is responsible for 75% of skin cancer deaths and an estimated 8,790 deaths in the U.S. annually. Of those deaths, two-thirds are men.
