Moles are like tiny, coloured spots on your skin. Lots of people have them, and usually, they're not a big deal unless they start to look different in size, shape, or colour.

Most of these harmless moles are either round or oval and have a smooth edge. Some may be flat or a little raised, and they can feel either smooth or slightly bumpy. Occasionally, they might have hair growing out of them. On brown or black skin, moles are often darker in colour.

They are removed surgically under local anaesthetic, after which they can be analysed in the labs, if appropriate.
