Q: Can a cancerous mole cause pain below the skin?
A: The answer to this is a bit tricky. Moles, or melanocytic nevi, can sometimes be painful even if nothing is wrong. In some cases, a normal benign mole will have a pimple forming directly beneath it, which can get temporarily stuck. This can cause more pain and take longer to clear up than a normal pimple because it can’t easily travel to the surface. Moles may get accidentally scratched and can become sore and inflamed. So, a painful mole is not always a sign of danger. And cancerous moles are often not at all painful. But some moles that become cancerous, which, in the case of a pigmented mole, means melanoma, can be accompanied by pain or unusual sensitivity different from the surrounding skin. So the best bet is, if a mole becomes painful and doesn’t get better in a few days or a week, see your dermatologist for an evaluation just to make extra sure. It’s always nice to get good news if everything is fine.
