Sometimes, moles can itch for harmless reasons, like dry skin, irritation from clothing, or insect bites. Most of the time, this isn't dangerous.

However, if a mole starts to itch frequently, changes in appearance, bleeds, becomes crusty, or grows, it could be a warning sign. In these cases, it's important to have it checked by a healthcare professional.

Monitoring changes in your moles regularly helps you catch any potential problems early, when treatment is simpler and more effective.
