A mole forms primarily due to an overgrowth of melanocytes, the cells in your skin that produce pigment (melanin).
Here's a more detailed breakdown:
-
Melanocyte Overgrowth: Moles, also known as nevi, arise when melanocytes cluster together instead of being evenly distributed throughout the skin. This clumping can be triggered by a variety of factors.
-
Genetic Predisposition: Some people are simply genetically predisposed to having more moles than others. Genetics play a significant role in how many moles an individual develops.
-
Sun Exposure: Exposure to ultraviolet (UV) radiation from the sun or tanning beds can stimulate melanocytes, potentially leading to an increased production of melanin and the formation of moles. Sunburns, especially during childhood, are strongly linked to increased mole development.
-
Hormonal Changes: Hormonal fluctuations during puberty, pregnancy, or other periods of hormonal change can also contribute to the development of new moles or changes in existing ones.
-
Location: Moles can appear anywhere on the skin, alone or in groups.
It's important to regularly monitor moles for changes in size, shape, color, or elevation, and to report any concerning changes to a dermatologist. While most moles are harmless, changes could indicate melanoma, a serious form of skin cancer.
