What Causes Moles?
5. Causes
The exact cause of moles is still unknown. There are no established environmental or genetic influences that contribute to the development of congenital nevi. Researchers who studied 144 children in Naples concluded that the development of moles in early life is due to environmental factors, constitutional factors, anatomical location, and mole evolution.
The specific genetic factors are also unclear. However, experts believe that those with a large number of moles may have inherited an autosomal dominant trait. Individuals with dysplastic nevus syndrome and familial atypical multiple nevus have a higher risk of melanoma. Studies have observed that moles are common in those with poor sun tolerance.
