Moles are common and usually harmless skin growths that can appear at any age. However, the sudden appearance of moles later in life may raise concerns for many people. While most moles that develop in adulthood are harmless, it’s essential to monitor any changes in moles and pay attention to certain warning signs that may indicate a need for further evaluation.

The Vascular Birthmark Center shares more about when you should be concerned with new nevi.

Why Do Moles (Nevi) Appear?

As we age, our skin undergoes various changes, and the development of new moles is not uncommon. Many adults notice new moles appearing, especially in areas exposed to the sun, such as the face, neck and arms. Some of these moles may be benign and not cause for alarm. However, it is crucial to be proactive in monitoring new moles and any changes in existing moles as we age.

New moles may emerge on your skin due to various factors. Some common reasons include:

1. Sun Exposure: Sun exposure, particularly to ultraviolet (UV) light, can cause melanocytes in the skin to multiply and form moles.
2. Genetics: Your genetic makeup can influence the development of moles. If your family members have many moles, you may be more prone to developing them as well.
3. Hormonal Changes: Fluctuations in hormones during puberty, pregnancy, or menopause can also prompt the formation of new moles by stimulating melanocytes.

While many moles that appear later in life are benign, it is important to be aware of warning signs that may indicate a potentially abnormal or cancerous mole.

Evaluating New Moles

The ABCDE rule is a helpful framework for identifying moles that may warrant further attention:

• A for Asymmetry: Check if one half of the mole does not match the other half.
• B for Border: Look for irregular, notched, or poorly defined borders.
• C for Color: Note if there are variations in color within the mole, such as different shades of brown, black, or even red or white.
• D for Diameter: Pay attention to the size of the mole, particularly if it is larger than a pencil eraser (6 millimeters).
• E for Evolution: Be alert to any changes in the mole’s size, shape, color, or elevation.

It’s important to keep in mind that not all atypical moles or changes in moles indicate cancer. However, any concerning changes should be promptly evaluated to determine whether further testing or a biopsy is necessary.

In addition to the ABCDE rule, the “ugly duckling” sign can also be a useful tool for identifying suspicious moles. This concept suggests that when examining a group of moles, the one that looks different from the others – the “ugly duckling” – may require closer attention.

Regular self-examinations of the skin can help individuals become familiar with their moles and identify any changes early on. It’s advisable to perform skin self-checks monthly and seek a professional evaluation if any mole appears worrisome or exhibits changes.
