When Should You Worry About a Mole?

Dr Gurgens Office - Examination of a mole

Most people have moles. In fact, it’s completely normal to have anywhere from 10 to 40 moles by adulthood. Most are harmless and remain unchanged for years. But occasionally, a mole can change in a way that signals something more serious—including melanoma, the deadliest form of skin cancer.

So how do you know when it’s time to stop watching a mole and schedule an appointment with a dermatologist?

If you live in Lady Lake, The Villages, Leesburg, or anywhere in Central Florida, understanding what to look for can help you catch potential skin cancers early, when treatment is most effective.

Most Moles Are Harmless

A mole (also called a nevus) is simply a collection of pigment-producing skin cells. They can appear almost anywhere on the body and vary in size, shape, and color.

Many people develop new moles throughout childhood and young adulthood. Genetics, age, and sun exposure all play a role in how many moles you have.

While most moles never become cancerous, it’s important to become familiar with your skin so you’ll notice if something changes.

The ABCDE Rule: What to Watch For

Dermatologists commonly use the ABCDE Rule to evaluate suspicious moles.

A — Asymmetry

Healthy moles are usually symmetrical. If one half doesn’t match the other, it’s worth having it evaluated.

B — Border

Normal moles tend to have smooth, even borders. Ragged, blurred, or irregular edges can be a warning sign.

C — Color

Most harmless moles are one consistent shade of brown or tan.

A mole with multiple colors—or black, blue, red, white, or gray areas—should be examined by a dermatologist.

D — Diameter

While melanomas are often larger than 6 millimeters (about the size of a pencil eraser), they can sometimes be smaller. Size alone doesn’t determine whether a mole is dangerous.

E — Evolving

This is often the most important sign.

If a mole changes in:

  • Size
  • Shape
  • Color
  • Height
  • Texture

or begins to itch, bleed, crust, or become painful, schedule a skin examination promptly.

Don’t Ignore the “Ugly Duckling”

Another helpful guideline is the Ugly Duckling Sign.

Most of your moles probably look somewhat similar. If one mole looks noticeably different from all the others, it deserves professional evaluation.

For example:

  • One mole is much darker.
  • One grows more quickly.
  • One has a different shape.
  • One suddenly becomes raised while others remain flat.

Even if it doesn’t meet every ABCDE criterion, an “ugly duckling” should be checked.

Florida Residents Face Increased Sun Exposure

Living in Florida has many benefits, but abundant sunshine also increases ultraviolet (UV) exposure throughout the year.

Long-term UV damage significantly increases the risk of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma.

People who spend time:

  • Gardening
  • Golfing
  • Boating
  • Walking outdoors
  • Swimming
  • Playing sports

should be especially diligent about performing regular skin self-exams and scheduling routine skin checks.

The American Academy of Dermatology recommends protecting your skin with sunscreen, seeking shade during peak sunlight hours, and wearing protective clothing whenever possible.

Who Is at Higher Risk?

Anyone can develop skin cancer, but your risk increases if you have:

  • Fair skin
  • Light-colored eyes
  • Blonde or red hair
  • A personal or family history of melanoma
  • Numerous moles
  • A history of blistering sunburns
  • Frequent tanning bed use
  • Significant lifetime sun exposure

Even individuals with darker skin tones can develop melanoma, making regular skin awareness important for everyone.

When Should You Schedule a Mole Check?

You don’t have to wait until you’re certain something is wrong.

A dermatologist should evaluate any mole that:

  • Is new after age 30
  • Changes over time
  • Bleeds or won’t heal
  • Becomes itchy or painful
  • Looks significantly different from your other moles
  • Causes concern for any reason

Many suspicious moles ultimately prove to be benign, but only a trained dermatologist can determine whether further testing or removal is appropriate.

If a mole appears concerning, a biopsy may be recommended to determine whether cancer cells are present.

What Happens During a Skin Examination?

Many patients delay appointments because they aren’t sure what to expect.

A professional skin examination is straightforward and typically takes only a short time.

Your dermatologist will carefully inspect your skin from head to toe, paying close attention to any concerning spots. If needed, specialized tools such as a dermatoscope allow for a closer examination of pigmented lesions.

If a mole requires additional evaluation, your dermatologist will explain the next steps and answer any questions you have.

Early Detection Can Save Lives

Most moles are completely harmless, but knowing what changes to watch for can make all the difference. Regular skin self-exams, sun protection, and routine dermatology visits are important parts of maintaining healthy skin—especially in sunny Florida.

If you’ve noticed a mole that’s changing, looks unusual, or simply doesn’t seem right, don’t ignore it. Early evaluation offers peace of mind and, when necessary, can lead to earlier diagnosis and more effective treatment.

Whether you’re in Lady Lake, The Villages, Leesburg, or the surrounding communities, scheduling a professional skin examination is one of the best steps you can take for your long-term skin health.
