How to Tell if Your Mole is Cancerous
- Asymmetry: Irregular shape; one half does not match the other
- Border: Ragged, notched, blurred or irregular in outline; spreading pigment
- Color: Uneven color; shades of black, brown, tan, white, grey, red, pink or blue
- Diameter: Increasing size; melanomas usually grow larger than a pencil eraser
Mole changes can indicate melanoma. Other symptoms of cancer or serious skin conditions include areas where the skin is broken or bleeding that won’t heal after a few weeks of targeted care.
When to See a Dermatologist
Get a mole checked if it’s:
- Growing fast
- Changing color quickly
Your risk for skin cancer increases if you:
- Are fair-skinned
- Have a history of intense sun exposure, especially in childhood
- Have more than 100 moles or large, irregular or unusual moles
- Have close blood relatives — parents, siblings, children — with melanoma
How to Prevent Skin Cancer
Skin cancer is highly preventable. Follow these simple steps for prevention:
- The best protection is a building – stay inside during the peak sunlight hours.
- Wear protective clothing, including long pants, long sleeves and a wide-brim hat. Clothing with SPF protection is available and a rating of at least 30-50 offers the most effective coverage.
- Wear sunscreen and protection for your eyes when in the sun.
- Avoid tanning beds.
- Avoid prolonged sun and ultraviolet (UV) light exposure.
- Use sunscreen effectively.
- Wear preventive gear (like gloves) when doing tasks that are demanding on your skin.
- Stop smoking.
- Properly clean your skin.
- Regularly examine your skin for lesions and possible melanoma.
