What are Moles?
Moles are common skin growths that appear as small, dark brown spots, and are caused when cells in the skin called melanocytes grow in clumps. While they usually appear in childhood and adolescence, they can appear at any age, and on any area of the body.
While most moles are harmless, they can become cancerous in some instances. Most moles are benign (non-cancerous), and normal moles are typically uniform in color and shape, remaining unchanged over time. That is why it is so important to regularly monitor your moles and other pigmented areas of skin. Comparing any new or changing spot to your existing moles can help you identify suspicious changes that may require medical attention.
While most moles are brown circles, they can also appear in different shapes, sizes, and colors.
- Shape: Most moles appear as either round or oval-shaped.
- Size: Moles are commonly less than ¼ inch in diameter. However, some moles that are present at birth can be much larger, covering large areas of the face, torso, or a limb.
- Color: Moles can appear as brown, tan, black, pink, or blue.
A skin examination should be a regular part of your preventative medical care, during which your doctor will carefully examine your skin to check for suspicious-looking moles. Use a full length mirror to thoroughly check your entire body for any new or changing spot, as these can be early signs of skin cancer.
The ABCDEs (Asymmetry, Border, Color, Diameter, Evolving) are important signs to watch for in moles that could be cancerous. If a mole looks atypical, a biopsy may be taken for examination under a microscope to check for cancerous cells. Irregular moles (dysplastic or atypical naevi) are a sign of higher risk for developing melanoma. Regular checkups and awareness can help you catch potential problems early and keep your skin healthy for years to come.
Risk Factors for Developing Moles
Moles occur in most people, but certain risk factors can increase the likelihood of developing many moles or atypical moles, which may raise the risk of skin cancer. Individuals with fair skin are more prone to developing moles because their skin contains less melanin, the pigment produced by cells called melanocytes. If you have a first-degree relative, such as a parent or sibling, who has had melanoma or many moles, your own risk is higher, according to the National Cancer Institute.
Sun exposure is one of the most significant risk factors for developing moles and, in some cases, cancerous moles. Ultraviolet (UV) rays from the sun can damage melanocytes, leading to the formation of new moles, dysplastic nevi (atypical moles), or even developing melanoma, a serious type of skin cancer. Both female moles and male moles can be affected, but those with a personal or family history of skin cancer, or who already have many moles, should be especially vigilant.
Genetics also play a major role. Some people are simply more likely to develop moles due to inherited traits. Moles tend to appear more frequently as people age, and congenital nevi—moles present at birth—can also occur. Hormonal changes, such as those during adolescence or pregnancy, may trigger the appearance of new moles.
To reduce your risk, limit sun exposure, use sunscreen, and perform regular skin checks to spot any new or changing spots. If you notice a new growth, uneven color, or a mole that looks different from your other skin spots, seek a medical review for further information. Those with a family history of skin cancer or many moles should consult a healthcare professional to assess their melanoma risk and discuss preventive strategies.
Understanding your personal risk factors is key to maintaining healthy, non-cancerous skin and preventing the development of cancerous moles. Regular checkups and awareness can help you catch potential problems early and keep your skin healthy for years to come.
Treatment Options for Moles
While most moles do not require treatment as they are not harmful, some people may wish to have them removed for cosmetic reasons. Be sure to tell Dr. Erwin if you are experiencing any new symptoms associated with a mole, or if you have noticed any changes in the mole over time. Some of the most popular techniques to remove a mole include:
Excision: Your doctor will remove the mole using a scalpel. Local anesthetic will be injected into the mole before the procedure so the process is not painful.
Ideal Candidates for Mole Treatment
Individuals who are bothered by the look or feel of a mole are often candidates for mole removal treatment. The best way to determine candidacy is through a consultation appointment with Dr. Erwin, during which she will assess your mole to determine the best treatment option for you.
