Expert Video - What are the signs and symptoms of melanoma?

Do you know the melanoma alphabet? Expert Jeffrey Weber, MD, PhD, from NYU Langone Medical Center describes how to check moles on your skin for signs of melanoma using the letters A, B, C, D, and E:

  • A – An asymmetrical, or irregular, shape
  • B – An irregular or uneven border
  • C – More than one color in the same lesion
  • D – A diameter bigger than a pencil eraser (about 6 millimeters)
  • E – evolution, or change, in the size or color of a mole.

If you notice any of these signs, make an appointment right away to have a dermatologist or primary care physician examine your skin.
Dr. Weber also discusses the most common locations for skin melanoma in men and women, and how other types of melanoma can be found, including sometimes by a dentist or eye doctor. Dr. Weber also discusses the challenge of diagnosing mucous membrane melanoma.
