During a biopsy, a small sample of the skin tissue from the mole is collected and examined to determine if the cells are cancerous. When a cancerous mole is identified, it needs to be removed right away so that the cancer doesn't spread beyond the skin and affect other parts of the body. There are several ways to get rid of moles, and the procedure is often simple.
Acquired moles are a form of benign neoplasm, while congenital moles, or congenital nevi, are considered a minor malformation or hamartoma and may be at a higher risk for melanoma. A mole can be either subdermal (under the skin) or a pigmented growth on the skin, formed mostly of a type of cell known as a melanocyte. melanocytic nevus (also known as  nevocytic nevus ) is a type of lesion that contains nevus cells (a type of melanocyte). Some sources equate the term mole with melanocytic nevus. Other sources reserve the term mole for other purposes.
