How do I find out if a mole is cancerous?
The best way to know if a mole is cancerous is to see a dermatologist for an annual skin cancer screening. If you have a history of skin cancer, your dermatologist may recommend screening more often. Meanwhile, you should schedule a checkup with your dermatologist if you notice any moles that:
- are asymmetrical
- have irregular borders
- are not uniform in color
- have a diameter that’s larger than a pencil eraser
- are evolving or changing in size, shape, or color
These types of moles should be evaluated by a dermatologist, who can then decide if they should be tested for skin cancer.
