Skin cancer is the most common form of cancer in the United States, with more than a million cases each year. Although cancer can affect skin anywhere on the body, it mostly appears on skin exposed to the sun.
Skin cells die every day and new ones form to replace them. If this process does not work properly, due to damage to DNA, skin cancer can form. If new cells form when they are not needed, or if older cells do not die, a growth of tissue, or tumor, can form. DNA damage can result from exposure to ultraviolet radiation from sunlight or tanning lamps. In some instances, skin cancer can affect skin that has not been exposed to the sun. Some factors can increase the risk of skin cancer, including moles, fair skin, age, heredity, and a weakened immune system.
The goal of skin cancer removal/reconstruction is to eliminate the cancerous lesion(s) and all malignant cells and return the lesion removal site to a normal appearance.
