Skin Cancer The Skin The skin is what makes up pretty much your whole body. It protects your body from heat, light, Infection and injury. The top layer of your skin is called the epidermis. It contains three types of cells: flat and scaly cells called squamous cells; round cells which are called basal cells; and the cells that give your skin its color which are called melanocytes.

What is Skin Cancer Skin cancer is a disease where cancer cells are found in the top layers of the skin. It is the most common of all the cancers around. Skin cancer may be the most common cancer, but is the most curable. Skin cancer is the most commonly found in people with light colored skin who spend a lot of time in the sun.

Three types of skin cancer There are three different types of skin cancer; basal cell carcinoma, squamous cell carcinoma, and melanoma.

Basel cell carcinoma, which develop in the basal, or bottom layer of the epidermis, is the most common type of skin cancer. It usually appears on the skin that has been in the sunlight too long. The second most common type is called squamous cell carcinoma which develops in the upper layers of the epidermis. This type of cancer occur on the skin that has been in the sun too long, such as the nose, forehead, lower and on the hands. Melanoma is the final type of skin cancer. This one is the most serious of all the cancers, the reason behind this is because it affects the cells that give the skin its color.

When radiation therapy is done they use x-rays to kill the cancer cells. It is done by a machine outside of the body which is called external radiation therapy.

Chemotherapy is the treatment that uses drugs to kill the cancer cells. Chemotherapy is often given as a cream or a lotion. Sometimes it is given as a pill or given to a person by injecting a needle into a vein or a muscle. This is called systemic treatment because the drug is placed into the bloodstream.
