If a nurse tells me I need to get a mole checked out as it doesn't look good, what does this mean?

[Guest]

I thought it looked okay.

You should see a doctor if the mole is patchy or has different shades of one color. Moles that turn red, white, or blue need to be checked out right away.

Diameter: Cancerous moles are usually larger in size than regular moles. Cancerous moles can start out small and grow.
