Most moles appear on the surface during childhood and adolescence. Moles will grow as the child (or teen) grows. Some moles will darken, and others will lighten. These changes are expected and seldom a sign of melanoma, the most severe skin cancer. Here are three facts that can help you find melanoma soon and get treatment. If you see a mole or other spot that is growing, itching, bleeding, or changing in any way, at once, make an appointment to see a dermatologist. Most moles do not require treatment. A dermatologist will remove a mole that: is bothersome (rubs against clothing, etc.), unattractive to a patient, and suspicious (could be skin cancer). After a mole is removed, the skin will heal. If the mole grows back, at once, make another appointment to see your dermatologist. The recurrence of a mole could be a sign of melanoma, the most severe type of skin cancer.
