Diagnosis

Your doctor can identify moles by visually inspecting your skin. You may choose to make a skin examination a regular part of your preventive medical care. Talk to your doctor about a schedule that's appropriate for you. During a skin exam, your doctor inspects your skin from head to toe.

If your doctor suspects that a mole may be cancerous, he or she may take a tissue sample (biopsy) and submit it for microscopic examination.

Treatment

Treatment of most moles usually isn't necessary. If your doctor thinks a mole is suspicious, he or she may take a tissue sample of it and have it tested to determine if it's cancerous.

Mole removal

If your mole is cancerous, your doctor will do a surgical procedure to remove it. If you have a mole in the beard area, you may want to have it removed by your doctor because shaving over it repeatedly may cause irritation. You may also want to have moles removed from other parts of your body that are vulnerable to trauma and friction.

Mole removal takes only a short time and is usually done on an outpatient basis. The procedure may leave a permanent scar. Options for mole removal include:

  • Surgical excision. In this method, your doctor numbs the area around the mole and cuts out the mole and a surrounding margin of healthy skin with a scalpel or a sharp punch device. Then he or she closes the wound with sutures.
  • Surgical shave. In this method, your doctor numbs the area around the mole and uses a small blade to cut around and beneath it. This technique is often used for smaller moles and doesn't require sutures.

If you notice that a mole has grown back, see your doctor promptly.

Cosmetic care

If you're self-conscious about a mole, these methods may help conceal it:

  • Makeup. Various products are available for concealing blemishes and moles. You may need to try several before you find one that works for you.
  • Hair removal. If you have a hair growing from a mole, you might try clipping it close to the skin's surface or plucking it. Or talk with your dermatologist about permanently removing the hair and the mole.

Anytime you cut or irritate a mole, keep the area clean. See your doctor if the mole doesn't heal.

Preparing for your appointment

If you have a mole that concerns you, your family doctor can usually let you know if it's normal or needs further investigation. He or she may then refer you to a doctor who specializes in skin disorders (dermatologist) for diagnosis and treatment.

It's a good idea to arrive for your appointment well-prepared. Here's some information to help you get ready.

What you can do

  • List any changes you've noticed or any new symptoms you're experiencing. Include any that may seem unrelated to the reason for which you scheduled the appointment.
  • Bring a list of all medications, vitamins or supplements that you're taking.
  • If you've had a melanoma or a mole removed in the past, note the location of the lesion and also the date of removal. If you have the biopsy report, bring it with you to the appointment.
  • Don't wear makeup or opaque nail polish to your appointment. These products make it difficult for your doctor to perform a thorough skin exam.
  • List questions to ask your doctor.

Your time with your doctor is limited, so preparing a list of questions can help you make the most of your time together. List your questions from most important to least important in case time runs out. For moles, some basic questions to ask your doctor include:

  • Do you think this mole might be cancerous?
  • What's the most appropriate course of action?
  • How can I tell if a mole needs to be looked at?
  • Can I prevent more moles from developing?
  • Do you have any brochures or other printed material that I can take home with me? What websites do you recommend?

In addition to the questions that you've prepared, don't hesitate to ask questions during your appointment.

What to expect from your doctor

Your doctor is likely to ask you a number of questions, such as:

  • When did you first notice this mole?
  • Have you always had it, or is it new?
  • Have you noticed any changes in this mole, such as its color or shape?
  • Have you had other moles surgically removed in the past? If so, do you know if they were unusual (atypical) or malignant?
  • Do you have a family history of atypical moles, melanoma or other cancers?
  • Have you had peeling sunburns or frequent exposure to ultraviolet radiation, such as from tanning beds?
