A mole (nevus) is a pigmented skin growth that can appear flat or raised, and may range in color from brown to flesh-toned or black. Moles can be present at birth or develop over time due to sun exposure, hormones, or genetics.
Most moles are benign, but some can become atypical or show early signs of melanoma. That’s why medical evaluation is important, especially if you notice changes in size, color, or texture.
