Moles and birthmarks are marks that appear on the skin. Moles are small spots, ranging from brown to black in color, and can appear anywhere on the body. They are generally caused by a cluster of pigment-producing cells called melanocytes and can vary in size and color. Sometimes, moles are present at birth, while other times, they develop over time.
Birthmarks are skin marks or discolorations that can either be present at birth or develop gradually over time. The causes of birthmarks and moles can include genetic factors, a family history of melanoma, UV exposure, or a weak immune system, among others.
While moles and birthmarks are usually harmless and pose no health risks, some people may feel self-conscious about them. For those who wish to remove them, options include laser treatment, therapy, or surgical removal.
