Question: How Do You Know If A Mole Is Cancerous?

The first sign of melanoma is typically a new spot on the skin, or a change in the size, shape or color of an existing mole.

Asymmetry: The mole has an irregular shape.

Border: The edge is not smooth, but irregular or notched.

Color: The mole has uneven shading or dark spots.

Can a doctor tell if a mole is cancerous just by looking at it?

How can a doctor tell if a mole is cancerous? A visual check of your skin only finds moles that may be cancer. It can’t tell you for sure that you have it. The only way to diagnose the condition is with a test called a biopsy.

When should I be worried about a mole?

If you have any moles that are larger than most, have smudgy or irregular edges, are uneven in colour or have some pinkness, you should see a doctor and get them checked. If you notice a change in colour or shape, or the mole becomes itchy, painful or starts to bleed, see a doctor immediately.

Are all asymmetrical moles cancerous?

Benign (non-cancerous) moles tend to be symmetrical. Remember, all moles are individual to the person, and no moles will be perfect. If a mole is asymmetrical seek advice from a skin cancer specialist.
