Frequently-asked questions about moles

Moles are common skin growths. They can appear anywhere on the body, and while most are harmless, some moles may need to be removed for medical or cosmetic reasons. We ask some frequently-asked questions about moles, including removal and whether they can grow back.

How are moles removed?

Moles can be removed using different techniques, depending on their size, type and location. The most common methods include:

• Surgical excision – The mole is cut out along with a small margin of surrounding skin. Stitches may be needed.
• Shave removal – A scalpel is used to shave the mole off the skin’s surface. This is typically used for raised moles.
• Laser removal – A laser is used to break down pigment in the mole. This is usually for smaller, non-cancerous moles.

A dermatologist can assess which method is most appropriate.

Why should a mole be removed?

Moles may be removed for various reasons, including:

• Medical concerns – If a mole changes in shape, size or colour, it may be a sign of melanoma or another skin condition.
• Irritation – Moles in areas prone to rubbing from clothing or shaving can become irritated or inflamed.
• Cosmetic reasons – Some people choose to remove moles for aesthetic purposes, especially if they are in a prominent location.

Can moles grow back after removal?

In some cases, a mole can grow back if it was not completely removed. This is more likely with shave removal or laser treatments, as these methods do not always remove the deeper layers of the mole. If a mole does return, it should be checked by a doctor to ensure it is not a sign of abnormal cell growth.

Are all moles dangerous?

Most moles are benign and don’t pose a risk to health. However, some may develop into melanoma, a type of skin cancer. Signs to watch for include:

• A mole changing in size, shape or colour.
• Irregular or blurred edges.
• Bleeding, itching or discomfort.

Regular self-examinations and dermatological checks can help identify any concerning changes early.

Can new moles appear over time?

Yes, new moles can develop at any age, but they are more common during childhood and adolescence. Hormonal changes, such as pregnancy, can also lead to the appearance of new moles. While this is usually normal, any new or unusual moles should be monitored for signs of abnormal growth.

If you have concerns about a mole or are considering removal, a specialist can assess your options and determine the best course of action.
