Skin Cancer

Types of Skin Cancer

The most common skin cancers are:

• Basal Cell Carcinoma rarely spreads beyond the site of the original growth but can grow larger and deeper.
• Squamous Cell Carcinoma – rarely spreads beyond the site of the original growth.
• Melanoma – affects cells called melanocytes, which create the pigment that colors skin, and is likely to spread to other parts of the body if not treated early.

Skin cancers originate in the top layer of the skin but sometimes grow downward, forming "roots" under the skin's surface. At times, these growths can be seen only with a microscope. What you see on your skin is sometimes only a small portion of the total tumor (like the tip of an iceberg).

What Are the Signs of Skin Cancer?

Be sure to check your skin regularly for signs of skin cancer, such as:

• Any change in appearance of an existing mole or blemish, including:

1. Size
2. Shape
3. Texture

• Appearance of a new mole or a sore that doesn't heal

Report any unusual findings to your primary care provider or dermatologist.
