Skin cancer is on the rise. Each year there are more than one million cases diagnosed in the
United States alone. There are different types of skin cancer. Basal cell and squamous cell carcinomas are the two most common forms of skin cancer. They’re both easily treated if they’re detected early. Some types of skin cancer aren’t as easily treated and they’re growing in numbers each year too.
According to the American Cancer Society there were about 120,000 new cases of
melanoma diagnosed in the United States last year. It’s not the most common type of skin
cancer but it is the most deadly. It kills almost 9,000 people in the United States annually.
Skin cancer forms when UV light from the sunshine or from tanning beds injures DNA in the
skin cells. Occasionally, the damage is enough that the body cannot repair it and the cells do
not naturally die off.
When this happens the new DNA can cause the skin cells to rapidly multiply. This is cancer
and the growth of new skin cells is referred to as a tumor. In the case of malignant tumors, the
cancerous cells begin to invade other tissues and the tumor spreads.
Cancers are named after the area where the DNA is damaged and the cancer originates. In thecase of melanoma, the cancer begins in the pigment-producing melanocytes in the basal layerof the skin. The basal layer is the very innermost layer of tissue in your skin. . .
