Moles or nevi are common. Almost every adult has a few moles. They often appear as small, dark brown spots and are caused by clusters of pigmented cells. Moles can develop anywhere on your body, including your scalp, armpits, under your nails, and between your fingers and toes. Most moles are harmless but they can sometimes become cancerous. Monitoring moles and other pigmented patches is an important step in detecting skin cancer, especially malignant melanoma. The risk of melanoma is higher if you have an extensive sun exposure history or use a tanning bed. If you have a mole of concern or would like a comprehensive total body skin exam, book a consultation with Dr. Doumit.
