What Is a Mole, Exactly?

A mole is a cluster of pigmented skin cells often appearing as a brown, black, or flesh-colored spot. Most people have between 10 and 40 moles, and many appear during childhood and adolescence. Moles can be:

  • Flat or raised
  • Smooth or rough
  • Round or irregular
  • Varying in size and color

Moles are usually benign. But when they change in appearance or start behaving differently, they could be a warning sign of skin cancer—especially melanoma, the most serious form.

The ABCDEs of Mole Monitoring

Dermatologists use the ABCDE rule to assess whether a mole may be atypical or potentially cancerous:

  • A – Asymmetry: One half of the mole doesn’t match the other.
  • B – Border: The edges are ragged, blurred, or irregular.
  • C – Color: There’s more than one color (brown, black, red, pink, white).
  • D – Diameter: Larger than a pencil eraser (6mm), though melanomas can be smaller.
  • E – Evolving: Changes in size, shape, color, or behavior (bleeding, itching, crusting).

If you notice even one of these warning signs, it’s time to have it evaluated by a medical dermatologist.

When Should a Mole Be Checked?

While many moles are harmless, you should get them checked by a dermatologist in Jacksonville if:

  • It’s new, and you’re over the age of 30
  • It bleeds, oozes, crusts, or scabs
  • It itches, hurts, or feels tender
  • It changes shape, color, or elevation
  • You have a personal or family history of melanoma or atypical moles
  • It looks significantly different from your other moles (the “ugly duckling” sign)

Should Every Mole Be Removed?

Not necessarily. Moles are only removed when medically necessary (suspicious, painful, or at-risk) or for cosmetic reasons. At Jacksonville Dermatology & Cosmetic Surgery, we offer safe, surgical mole removal options in-office when removal is appropriate.

Mole removal may be recommended if:

  • A mole is biopsied, and the results are abnormal
  • It causes physical discomfort (snagging, rubbing, irritation)
  • You’re concerned about cosmetic appearance (especially on the face or neck)
  • It’s in a high-friction area like the waistband, bra line, or underarms

Can I Prevent Moles from Becoming Cancerous?

You can’t always prevent moles, but you can reduce your risk of melanoma by protecting your skin and monitoring it closely:

  • Use broad-spectrum SPF 30+ sunscreen daily, even on cloudy days.
  • Wear protective clothing and seek shade between 10 AM and 4 PM.
  • Avoid tanning beds.
  • Perform monthly skin self-exams using a mirror or partner assistance.
  • Schedule annual full-body skin checks with your dermatologist.
