You asked: How do dermatologists determine 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. If your doctor thinks a mole is a problem, they will give you a shot of numbing medicine, then scrape off as much of the mole as possible.

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

Unfortunately, you can’t tell by looking at a mole whether it’s cancerous or what type it is. It could very well be a normal skin spot with an abnormal appearance. A dermatologist can’t always tell the difference either.

How does a dermatologist evaluate a mole for melanoma?

If your dermatologist determines that the mole is a concern, he or she will perform a skin biopsy, in which a small sample of the mole is taken to examine under a microscope. A diagnosis can usually be made in less than a week. If the mole is found to be cancerous, it needs to be completely removed.

Can a dermatologist see melanoma?

What happens at a dermatology appointment for moles?

A skin specialist (dermatologist) or plastic surgeon will examine the mole and the rest of your skin. They may remove the mole and send it for testing (biopsy) to check whether it’s cancerous.
