Moles themselves are usually harmless skin growths caused by clusters of pigmented cells, and they don't directly cause infections. However, there are situations where a mole might become problematic, particularly if it gets injured, becomes infected, or is linked to a disease.

A mole can become infected if it's scratched, cut, or irritated. This can happen through regular activities like shaving, accidental scraping, or picking at the mole.
