  • The increase in fat mass in the body of a woman more than 4 kg compared with that weight at the age of 30 years.
  • High estrogen levels.
  • Diseases of the thyroid gland.
  • The high incidence of breast cancer in the family.
  • Transferred mastitis.
  • Injury breast.
  • Not to breastfeed (in recent times, many gynecologists believe that over a long period of feeding (up to two years) is a risk factor).
