Basal Cell and Squamous Cell Skin Cancer

Basal cell and squamous cell skin cancer are the most common forms of cancer and have the highest cure rate of any cancer. They are also the most preventable cancer.

The skin is the body's outermost covering and offers protection from heat and light, injury, and infection. It also helps regulate body temperature and stores water, fat, and vitamin D. The skin is made up of two main layers: the outer epidermis and the inner dermis. The epidermis contains three kinds of cells: flat, scaly cells on the surface called squamous cells; round cells called basal cells; and melanocytes, which give the skin its color.

Many skin cancers can be seen by the naked eye. It is recommended that all persons become familiar with the way their skin looks and that everyone perform a monthly skin self-exam.

Incidence

Basal cell and squamous cell skin cancers are more common among light-skinned people who burn or freckle easily; Caucasians are approximately 10 times more likely to develop skin cancer than African-Americans. Men are more likely to develop it than women, as are persons over age 55. However, the incidence of younger people being diagnosed with basal cell or squamous cell skin cancer is increasing.

The majority of cases are caused by high exposure to the sun and ultraviolet radiation.

Signs & Symptoms

Early signs of skin cancer may include a sore or a mark on the skin that changes in size, a new growth or a sore than does not heal.
