What causes skin moles and are they ormal?
Moles are very common and therefore ‘normal’ for most people: the average adult has between ten to forty at any time. Moles are collections of melanocytes that are producing melanin to give a concentrated ‘patch’ of colour in the skin. Some people are born with a few or many moles and some families have more moles than others. We think others develop moles as a response to sun exposure. The type of moles that doctors are most interested in are those that can become a type of skin cancer (melanoma). You can have any number of moles, and most never become cancerous.
