The growth of moles on the face is related to congenital abnormalities of embryonic development, heredity and environmental factors.
1. Congenital embryonic developmental abnormality: nevus is a common benign tumor, which is related to the developmental defects of the body in the embryonic period, and is gradually revealed with the growth of age.
2. Hereditary factors: the formation of nevus has a certain genetic tendency, and the chances of nevus reappearing in people with similar conditions in the family will increase significantly.
3. Environmental factors: the presence of a large number of chemical substances in the environment or prolonged exposure to the sun are important factors that induce the formation of moles.
Generally speaking, moles do not cause too much impact on the body except affecting the aesthetics, but for a large number of moles with large size and abnormal shape, it is necessary to carry out standardized treatment under the guidance of doctors in a timely manner.
