Moles are common harmless skin lesions, due to the accumulation of pigment cells in the skin. Almost everyone has at least one of them and they can either be present at birth or appear later in life. Fairer skinned individuals tend to have more moles than darker skinned individuals.
You should see a dermatologist to get your mole reviewed if:
Your dermatologist will do a complete examination of your entire skin, in particular focusing on any moles or suspicious lesions with a special skin magnifier (dermatoscope). Any suspicious moles will be biopsied and sent for histological analysis of the skin cells.
If you are at high risk for skin cancer, you should have a regular skin check done yearly:
Your dermatologist will be able to spot any suspicious looking moles or other pre cancerous lesions or non- melanoma skin cancers during your yearly checks.
