Skin Cancer Every hour one American is killed by skin cancer and every thirty seconds one American gets skin cancer. Cancer is a deadly disease that alters the DNA of a skin cell and causes it to reproduce at a rapid pace. This overproduction of cells can be harmful and in many cases deadly. Out of these cancers the most common is Basal cell carcinoma. Many steps have been made in the treatment of Basal Cell Carcinoma, some have been very successful and some not. The cells that have the altered DNA are called malignant or cancerous cells. These cells are found in the outer layers of the skin. The skin\'s main job is to protect the body from infections and to insulate the body to keep it at the proper temperature. The first layer of skin is called the epidermis. This is the layer that is closest to the surface of the skin. There are three types of cells in this layer. The first is the squamous. The squamous cells are flat and scaly and are located closest to the surface of the skin. Second are the basal cells and finally are the melanocytes, which give the skin its color.
