According to the plastic surgery expert of Guangzhou New Age Hospital, because people usually only have one or two babies and don't need many mammary glands, only one pair of mammary glands in the chest continues to develop and form nipple buds. When the embryo is three months old, the mammary duct is formed. The rest of the mammary gland primordia generally gradually fade after the ninth week of embryo. If the degeneration is not complete, redundant breasts will be formed after birth, which is medically called accessory breast or mastopathy.
Some auxiliary breasts are simply fat accumulation; However, some auxiliary breasts are relatively small, although the structure of nipples, areola and mammary glands is complete.
Growing a pair of breasts is not terrible. According to the different conditions of the breasts, you can choose the corresponding liposuction to remove the breasts, or surgical resection!
