Skin Changes - Topic Overview

(continued)

Some common skin growths include:

  • Moles. Most people have between 10 and 40 moles. You may continue to form new moles until you are in your 40s. Moles may change over time. They can gradually get bigger, develop a hair, become more raised, get lighter in color, fade away, or fall off.
  • Skin tags. These are harmless growths that appear in the skin folds on the neck, under the arms, under the breasts, or in the groin. They begin as small fleshy brown spots and may grow a small stalk. Skin tags never turn into skin cancer.
  • Seborrheic keratoses, which are harmless skin growths that are found most often on the chest or back; occasionally on the scalp, face, or neck; and less commonly below the waist. They begin as slightly raised tan spots that develop a crusty appearance like that of a wart. Seborrheic keratoses never turn into skin cancer. For more information, see the topic Seborrheic Keratosis.

Treatment of a skin change depends on what is causing the skin change and what other symptoms you are having. Moles, skin tags, and other growths can be removed if they become irritated, bleed, or cause embarrassment.

While most skin changes are normal and occur with aging, some may be caused by cancer. Skin cancer may start as a growth or mole, a change in a growth or mole, a sore that does not heal, or irritation of the skin. It is the most common form of cancer in North America.

Skin cancer destroys skin cells and tissues and can spread (metastasize) to other parts of the body. The three most common types of skin cancer are basal cell cancer, squamous cell cancer, and melanoma. See a picture of the ABCDEs of melanomacamera.gif.

Early detection and treatment of skin cancer can help prevent problems. Treatment depends on the type and location of the growth and how advanced it is when it is diagnosed. Surgery to remove the growth will help determine what treatment will be needed. For more information, see the topics Skin Cancer, Melanoma and Skin Cancer, Nonmelanoma.

Check your symptoms to decide if and when you should see a doctor.
