Understanding Moles: What They Are and Why People Remove Them

A mole is a growth of skin cells that typically appears as a small, dark spot on your skin. Moles are extremely common—most people have between 10 and 40 moles on their body by adulthood. They can appear anywhere on your skin and may be present from birth or develop over time, especially after sun exposure during childhood and young adulthood.

Moles form when melanocytes (the cells that produce skin color) grow together in clusters rather than spreading out evenly across your skin. This clustering creates the dark appearance. Most moles are benign, meaning they are not cancerous and pose no health risk. However, some people choose to remove moles for cosmetic reasons, because they find them bothersome, or because they want them evaluated by a dermatologist to ensure they are not cancerous.

According to the American Academy of Dermatology, it is normal to have multiple moles, and most people do. However, having more than 50 moles increases your risk of developing melanoma (a serious type of skin cancer), so monitoring your moles becomes more important. People with certain risk factors—such as a family history of melanoma, fair skin, or a history of sunburns—may want to have their moles checked by a healthcare provider.

Moles can change over time. Some may fade or disappear on their own, while others may darken or grow slightly larger. Changes in a mole, especially rapid changes, warrant evaluation by a dermatologist. Understanding your moles and knowing your removal options can help you make informed decisions about your skin health.

Takeaway: Moles are normal skin growths that are usually harmless. Understanding what moles are, why they form, and how they may change helps you decide whether removal is right for you and when to seek professional evaluation.

Medical and Cosmetic Reasons for Mole Removal

People remove moles for several reasons, which can be divided into medical and cosmetic categories. Medical reasons include concerns about skin cancer, irritation from clothing or shaving, or changes in the mole's appearance that suggest it may be cancerous. Cosmetic reasons include simply not liking how a mole looks or where it is located on the body.

From a medical standpoint, dermatologists use the ABCDE rule to evaluate whether a mole may be concerning. This rule looks at whether a mole is asymmetrical (A), has uneven borders (B), has multiple colors (C), is larger than a pencil eraser in diameter (D), or is evolving or changing (E). If your mole shows any of these signs, it warrants professional evaluation. A dermatologist can examine the mole and, if necessary, perform a biopsy—a simple procedure where a small sample of skin is removed and tested for cancer.

Moles located on areas that experience friction—such as where a bra strap, waistband, or shoe rubs against your skin—may become irritated or bleed. Some people have moles that they catch while shaving or that regularly become irritated. In these cases, removal can prevent ongoing discomfort and potential infection. A dermatologist can remove such moles to eliminate the irritation.

Cosmetically, mole removal is a personal choice. Some people feel self-conscious about a mole on their face or other visible area and choose to have it removed. Others may have a mole that affects their appearance in a way that bothers them. Professional removal ensures the mole is removed cleanly and with minimal scarring, which differs from home removal methods that can cause infection, scarring, or incomplete removal.

Takeaway: Mole removal may be medically necessary if a mole shows signs of skin cancer or causes physical irritation, or cosmetic if you simply prefer not to have it. Understanding your reasons for considering removal helps you determine whether professional evaluation is needed.

Professional Removal Methods Used by Dermatologists

Dermatologists offer several proven methods for removing moles, each with its own advantages and appropriate uses. The method chosen depends on the mole's size, depth, location, and whether a biopsy is needed to rule out cancer. Understanding these methods helps you know what to expect if you decide to pursue professional removal.

Surgical Excision is one of the most common methods. During this procedure, the dermatologist uses a scalpel to cut out the mole along with a small margin of surrounding healthy skin. This method allows the tissue to be sent for biopsy if needed and typically results in a small scar that fades over time. The procedure is performed under local anesthesia (numbing medication), so you feel pressure but not pain. This method works well for raised moles, moles that may be cancerous, or moles you want completely removed.

Shave Excision involves using a thin blade to shave off the mole at the skin surface. This method works best for moles that are raised above the skin. It does not require stitches and typically heals well with minimal scarring. However, because this method does not remove the root of the mole, there is a small chance the mole could regrow. Shave excision cannot be used if there is concern about cancer, since it does not remove all layers of skin for biopsy.

Laser Removal uses a focused beam of light to break down the cells that make up the mole. This method is often used for cosmetic removal of flat, pigmented moles. It may require multiple sessions and works best on smaller moles. Laser removal typically leaves minimal scarring and does not require stitches. However, it cannot be used if cancer is suspected because the mole tissue cannot be sent for testing.

Electrocautery and Chemical Cautery involve using electrical current or chemical solutions to burn away mole tissue. These methods are less common now but may be used for specific types of moles. They typically do not allow for biopsy and work best on small, flat moles.

Takeaway: Professional removal methods range from surgical excision (best for potentially cancerous moles) to laser and shave methods (best for cosmetic removal). Your dermatologist will recommend the method most appropriate for your specific mole based on its characteristics and your goals.

At-Home Mole Removal: Risks and Why Professional Removal Is Safer

Many at-home mole removal products and methods are available for purchase, including creams, oils, patches, and tools that claim to remove moles without visiting a doctor. Despite their availability and marketing claims, medical organizations including the American Academy of Dermatology strongly advise against at-home removal. Understanding the risks explains why professional removal is the safer choice.

The most significant risk of at-home removal is the inability to determine whether a mole is cancerous. If you remove a mole yourself or use an at-home product, there is no way to examine the mole tissue under a microscope to confirm it is benign. If the mole is actually a melanoma or other skin cancer, delaying professional diagnosis could allow the cancer to progress to a more dangerous stage. Early detection of skin cancer significantly improves treatment outcomes, so any mole you are concerned about should be evaluated by a professional before removal.

At-home removal methods also carry high risks of infection, scarring, and incomplete removal. When you cut into your skin without sterile technique and proper wound care, bacteria can enter the wound, leading to infection that may require antibiotic treatment. Improper removal technique often leaves scars that are more noticeable than the original mole. Additionally, if the mole is not completely removed, it may regrow, and you may need professional removal anyway after dealing with infection or scarring.

At-home removal creams and products often contain harsh chemicals that can burn surrounding healthy skin, causing discoloration, scarring, or permanent damage. Some products contain unregulated ingredients with unknown safety profiles. Natural oils and remedies marketed for mole removal typically lack scientific evidence supporting their effectiveness and may cause skin irritation or allergic reactions.

Professional removal performed by a dermatologist uses sterile technique, proper anesthesia, and methods designed to minimize scarring while ensuring complete removal. If cancer is a concern, professional removal allows tissue to be examined microscopically. If complications occur, your dermatologist can address them immediately rather than leaving you to manage infection
