Skin cancer is the most common form of human cancer. It is estimated that over 1 million new cases occur annually. The annual rates of all forms of skin cancer are increasing each year, representing a growing public concern. It has also been estimated that nearly half of all Americans who live to age 65 will develop skin cancer at least once.
We have all heard about skin cancer, but do we really know what it is? Skin cancer forms in our skin cells. Our body’s cells multiply in order for us to grow and remain healthy. When cells start growing uncontrollably, they form a growth called a tumor, which is either malignant or benign. Malignant tumors are cancerous and can spread to other parts of the body, while benign tumors are non-cancerous and do not spread. Since skin cancer forms in the outer layers of the skin, the tumor is usually visible and looks like raised skin lesion, irritated patch of skin, or mole.
