While very few moles become cancerous, overtime they do pose a risk for skin cancer. Cancerous moles don’t typically look like other moles. Cancerous moles can have an unusual shape, irregular borders, discoloration and often a different texture. When a cancerous mole is identified it needs to be removed immediately.

Treatment for cancerous moles is surgical removal. How the surgical removal is done is dependent upon factors such as the size, location and how deep it goes into the tissue. The best way to prevent moles from becoming cancerous is by checking them regularly for abnormalities and always using sunscreen.
