Changing Mole: When to Get Checked and Key Results to Watch
Learn when to get a changing mole checked and which results to monitor for potential skin health concerns.
Moles are common skin growths that most people have. While they are usually harmless, changes in a mole's appearance can be a sign of skin conditions, including skin cancer. Understanding when to get a mole checked and what changes to watch for can help you maintain your skin health.
What are moles?
Moles, also known as nevi, are clusters of pigmented cells that appear as small, dark brown spots on the skin. They are usually harmless and can appear anywhere on the body. Moles can vary in color and size, and they may change over time. Most moles are benign, meaning they are not cancerous.
Why mole changes matter
Changes in a mole's size, shape, color, or texture may indicate a risk of skin cancer, including melanoma, the most serious type. Noticing and monitoring these changes can be crucial for early detection and treatment.
What changes to watch for
The ABCDE rule is a helpful guide to identify concerning changes in moles:
- Asymmetry: One half of the mole does not match the other half.
- Border: The edges of the mole are irregular, ragged, or blurred.
- Color: The mole has multiple colors or has changed color.
- Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).
- Evolving: The mole is changing in size, shape, or color over time.
If you notice any of these changes, it is important to have the mole evaluated by a healthcare professional.
Diagnosing a changing mole
A dermatologist, a doctor specializing in skin conditions, can assess a mole through a visual examination and, if necessary, a biopsy. A biopsy involves removing a small sample of the mole for laboratory analysis to determine if cancer cells are present.
Frequently asked questions
