Mole (medicine)

A mole, in medicine, is a benign (non-cancerous) growth on the skin, formed by an overgrowth of pigment-producing cells called melanocytes. Moles vary in color, size, and shape, typically appearing as small, dark spots, but some can be flesh-colored or pink. While most moles are harmless, changes in their appearance—such as size, shape, color, or new symptoms like itching or bleeding—can indicate skin cancer, particularly melanoma. Regular skin exams help monitor moles for warning signs, emphasizing the importance of early detection and consultation with a healthcare professional if any changes occur.
