How do I know if a Mole is Cancerous?

Skin moles are generally classified in three different types:

  • Atypical moles or dysplastic nevi. These moles are the largest of the three types and have a characteristic irregular shape and color. These moles are hereditary or genetic moles that may have an increased risk for developing into a cancerous lesion.
  • Congenital moles or congenital nevus. These moles are present at birth and may be at a risk of developing into cancerous lesions. Around 1% of people have these moles from their birth.
  • Acquired moles. These moles are the most common type of moles, developed throughout childhood or early adulthood. Acquired moles remain smaller than a quarter inch, and typically appear after excessive exposure to the sun. These moles typically don’t develop into cancerous lesions.

If you have concerns about your mole, a skin doctor or our dermatologist San Diego can assist you. A suspicious looking skin lesion like a mole can be considered a sign of malignant melanoma, one of the more life-threatening forms of skin cancer.

  • Asymmetry, or if one side of your mole doesn’t look like its opposing side.
  • Border or irregular border, if the border of your skin lesion looks irregular or poorly defined.
  • Colors that vary, or if your mole have more than one shade of color, like brown, black or red.
  • Diameter, or if your mole has a diameter larger than that of a pencil eraser.
  • Evolution, if any part of your mole changes or evolves over time.
