Is it a mole or could it be melanoma?

Here are some things that increase the chance that it is melanoma (skin cancer). You should see your doctor if you have a mole with any of these.

  • A - Asymmetry: The shape of the mole is not round and two sides of a mole do not look the same.
  • B - Border: The borders of the mole are irregular, blurry or look like they are "leaking" pigment (color) into the skin next to the mole.
  • C - Color: A mole which changes color or contains more than one color.
  • D - Diameter: Size larger than a pencil eraser (> 6 mm or > 0.25 inches).
  • E - Evolving: The mole is changing in size, shape, or color.

What are other signs of skin cancer?

See your doctor if any of these occur.

  • A new skin growth or mole
  • A skin growth or mole that bleeds, feels rough to touch, or feels irritated
  • A growing skin lesion in sun-damaged areas of skin

Care Advice


  1. What You Should Know:
    • Moles are small growths on the skin. Most adults have between 10 and 40 moles.
    • Normal moles are brown, tan, or pink. They are round or oval. They can be flat or slightly raised. They are smaller than a pencil eraser.
    • An abnormal mole does not look the same as your other moles. It may be growing, change color, or look different in some other way. If you have a mole that is changing, you should see your doctor to get it checked.
  2. Call Your Doctor If:
    • Any change in a mole or growth
    • A mole that looks different
    • Fever or pain occurs
    • You think you need to be seen
    • You get worse

Skin Health

  1. Avoid Sun Exposure:
    • Protect your skin from too much sun. Too much sun and sunburn can damage your skin. It increases your risk of getting skin cancer later in life.
    • Use sunscreen if you are out in the sun.
    • Stay in the shade during the middle of the day.
    • Wear protective clothing such as long pants and long-sleeve shirts. Wear a wide-brimmed hat to keep the sun off your face and neck.
    • Do not use tanning beds. Tanning beds can also cause skin damage.
  2. Monthly Skin Self-exam:
    • Perform a skin self-exam once a month.
    • Stand in front of a mirror. Look at every inch of your skin for new moles or changes in old ones.

And remember, contact your doctor if you develop any of the 'Call Your Doctor' symptoms.
