If you are in a high-risk group for skin cancer or have ever been treated for some form of the disease, you should familiarize yourself with how skin cancers look. Examine your skin from head to toe every few months, using a full-length mirror and hand mirror to check your mouth, nose, scalp, palms, soles, backs of ears, genital area, and between the buttocks. Cover every inch of skin and pay special attention to moles and sites of previous skin cancer. If you find a suspicious growth, have it examined by your dermatologist.
Squamous cell carcinoma (SCC) is the second most common form of skin cancer. It’s usually found on areas of the body damaged by UV rays from the sun or tanning beds. Sun-exposed skin includes the head, neck, ears, lips, arms, legs, and hands.
SCC is a fairly slow-growing skin cancer. Unlike other types of skin cancer, it can spread to the tissues, bones, and nearby lymph nodes, where it may become hard to treat. When caught early, it’s easy to treat.
