Moles & changing skin spots
Moles are skin growths formed by clusters of pigment-producing cells. Many are common, stable features of the skin. An unusual mole or a spot that changes in size, color, shape, or another way deserves professional attention.

BEYOND THE DEFINITION
You don’t need the perfect words.
Understanding the basics can help you ask.
Arrange a skin assessment for a mole that changes size, shape, or color, or becomes itchy, painful, crusted, or bleeding. A new unusual mark that persists also deserves review. These signs do not confirm cancer, but they should not be dismissed as routine aging. [2]
Checking your skin regularly helps you become familiar with your usual spots and notice changes. Sun protection matters too: shade, protective clothing, and sunscreen help limit ultraviolet exposure. Avoid tanning beds. These steps support prevention, but they cannot establish whether a particular spot is harmless. [2]
ALSO WORTH KNOWING [1]
This glossary cannot rule out skin cancer. A clinician should examine unusual or changing spots. [1]
THE CLINICAL CONVERSATION
A clinician may recommend specialist review when a spot looks concerning. The purpose is to identify what it is and whether further evaluation or removal is needed. Describe how it changed and any bleeding or discomfort; do not wait for a spot to become painful. [2]
Bring the context that matters to you—your routines, your priorities, and your experience after service.

A FEW STRAIGHT ANSWERS
General information to help you prepare for a conversation about your own health.
No. Moles may be flat or raised, and some have hairs. A clinician considers changes and other features rather than relying on one characteristic to determine the next step. [2]
Yes. New moles can appear over time, including in adulthood. However, an unusual or changing spot should still be checked rather than assumed to be an ordinary mole. [1]
