Types of Skin Cancer

Skin cancer is a serious disease that can affect anyone. It is the most common form of cancer. If caught early, skin cancer can often be treated with success. But in some cases, it is life-threatening. To play it safe, start doing monthly skin checkups. If you see any changes in your skin, contact your doctor right away. Read on to learn more.

Squamous Cell Cancer

Basal cell cancer is the most common skin cancer. Lesions often appear on the face, ears, neck, trunk, or arms. Varying in color, these lesions may be waxy, pearly, scaly, or scarlike. Tiny blood vessels may be seen through the lesion’s surface. These lesions sometime bleed easily and might not heal well.

Melanoma is a more dangerous type of skin cancer because it is more likely to grow and spread than basal or squamous cell  cancers.. A melanoma lesion’s borders are often poorly defined. It is often brown or black, but it may be mixed in color. The shape and size of melanoma lesions tend to differ from 1 side to the other.

 

Squamous cell cancer is also a common type of skin cancer. Lesions often form on the face (commonly on the lips), ears, neck, hands, or arms. The lesions are firm, red bumps or flat, scaly, crusty growths.

Bowen’s disease is an early stage of squamous cell cancer. The lesions are usually  red, crusty, scaly growths with well-defined borders.

 

There are other types of skin cancer as well, including Merkel cell cancer and cutaneous (skin) lymphomas, but these cancers are rare.

Actinic Keratosis

A precancerous skin change

Actinic keratosis is not skin cancer. It is a common, precancerous skin change that can turn into a squamous cell skin cancer if left untreated over a long period of time. Actinic keratosis lesions tend to appear on sun-exposed parts of the body. They can be reddish-brown or skin-colored. These lesions are most often raised, scaly, and rough, like sandpaper. In some cases, actinic keratosis lesions are painful. Getting early treatment for actinic keratoses almost always cures the lesions. Treatment includes freezing them with liquid nitrogen or applying a topical prescription medication. You may need a biopsy so your health care provider can find out whether it is advanced actinic keratosis or an early skin cancer.
