What Is a Mole?

Moles are very common in adults. Most adults have at least a few, but many have more. Some are present at birth (called congenital nevi), but often they develop during childhood and adolescence. Moles can darken during pregnancy or from sun exposure. New moles as an adult are not common.

Moles occur when a type of cell known as a melanocyte grows in a cluster instead of being spread throughout the skin. Melanocytes are a type of cell that produce the pigment in the skin. They are also the type of cell that can develop melanoma, a dangerous type of skin cancer. Melanoma isn’t exclusive to moles however; it can develop anywhere on the skin and even in the eyes, digestive tract, etc. Most moles will never develop cancer.

At Home Mole Checks: What You Need to Know

You are more familiar with your skin than anyone else which puts you in a good position to watch for melanoma. You should perform regular checks on your skin. Look for changes (new moles, changes to existing ones, etc.) and come see Dr. Matarasso if you spot anything concerning. Many melanomas have irregular characteristics. To remember what to look for, use the ABCDE rule.

  1. Asymmetry: Look for moles where one side doesn’t match the other.
  2. Border: Ragged edges, notches, and blurred outlines need a second look by a doctor.
  3. Color: Moles can be many colors (black, brown, tan, gray, white, red, blue, etc.), but they are typically only one single color. Uneven or multiple colors warrant a visit to Dr. Matarasso.
  4. Diameter: Most melanomas are larger than 6 mm (about ¼ inch wide).
  5. Evolving: If you spot changes, come on in.

Melanomas can vary greatly in their appearance. Some have all the characteristics of a problem mole, while others have only a feature or two on the list. Other things to watch for include bleeding or itching. If you’re concerned, come see us. Dr. Matarasso can help you determine if a mole needs removal and testing. Melanoma is curable if caught early.
