When Should You See Your Doctor for a Mole?

Everyone has moles on their skin. According to Everyday Health, it’s normal to have between 10 and 40 moles. Some you’re born with, while others develop later in life. Most moles appear by age 20, but sun exposure can cause more moles to form or make the ones you already have appear darker.  

This poses the question—which moles are harmless, and when should you see your doctor for a mole? 

Keep an eye on your moles, and be watchful for any new moles or changes to your existing ones. If you have a family history of skin cancer or atypical moles, your doctor may suggest routine evaluations from a dermatologist. 

The ABCDEs of Melanoma 

The indicators of skin cancer can be labeled A through E. If you see any of them, contact your doctor for advice. 

  • A is for Asymmetry: Normal moles are small and circular. A mole that looks different on one side than the other might be precancerous. 
  • B is for Border: A mole with jagged, uneven, or otherwise irregular borders is a cause for concern. 
  • C is for Color: Most moles are a single color. If yours has various shades of black, brown, red, white, or even blue, schedule an appointment with a dermatologist. 
  • D is for Diameter: Large moles are more likely to be cancerous. Any mole with a diameter larger than a pencil eraser should be evaluated. 
  • E is for Evolution: A mole that changes size, shape, or color over time could indicate cancer. 

Moles to Watch Out For 

Keep in mind that moles tend to enlarge and stick out, becoming a skin tag in the process. This is perfectly normal and not a sign of cancer. Most moles are harmless and will never cause problems. However, in addition to knowing your ABCDEs, you should also watch out for these specific types of moles: 

  • New moles: Not all new moles are dangerous, but be watchful of any that develop after age 20, especially on any areas that get excessive sun exposure. 
  • Bothersome moles: Any itchy, bleeding, or painful moles deserve an evaluation from a dermatologist. 
  • Atypical moles: These types of moles showcase the ABCDEs of melanoma. They often run in families and may increase your risk of developing skin cancer. 

Why See a Doctor About a Mole? 

It’s important to consult with a doctor about suspicious moles because they are often early indicators of malignant melanoma, a life-threatening type of skin cancer. Melanoma is nearly 100 percent curable—as long as you receive an early diagnosis and treatment.
