There are many cases of nipple retraction in daily life, which are not only related to congenital factors, but also directly related to daily habits. It is necessary to pay attention to reasonable prevention in daily life.
The cause of nipple retraction
1. Primary inverted nipple
(1) Smooth muscle dysplasia. The nipple has 15-20 openings for milk ducts, with smooth muscle fibers surrounding the ducts. The nipple is surrounded by the ducts and the muscle fiber bundles inserted into the dermal layer of the nipple stretch inward. The texture of these muscle bundles is significantly different from that of the ducts.
(2) Dysplasia of the milk duct. Incompletely developed milk ducts cannot be ducted.
(3) Insufficient support of the supporting tissue under the nipple.
2. Secondary inverted nipple
(1) Disease. Invaded ducts, ligaments, and fascia contract.
(2) Malignant breast tumors. Women with normal breasts should undergo mammography and other examinations to check for the presence of malignant breast tumors if there is no obvious cause of nipple retraction.
(3) Breast surgery. When applying dermal pedicle in Mammaplasty, tension and scar contraction can also lead to nipple invagination.
3. Other common reasons
(1) The clothes are too tight. Women's underwear is too tight during the period of breast development, which easily leads to Inverted nipple.
(2) Improper use of bras. Bras that are too small, too tight, or used prematurely can cause Inverted nipple.
(3) Related to genetics. In clinical observation, if the mother and her maternal generation have a history of Inverted nipple, the next generation is more likely to suffer from Inverted nipple than the normal people.
Classification of nipple invagination
1. One is partial nipple recession, which exists in the neck of the nipple and can be easily squeezed out. After being squeezed out, the size of the nipple is similar to that of ordinary people.
2. The secondary nipple is completely sunken in the areola, but when squeezed out by hand, the nipple is smaller than normal and there is often no nipple neck.
3. Completely buried under the areola at 3 degrees, unable to squeeze out the sunken nipple. If accompanied by periductal Mastitis, the patient may have erythema and pain around the areola, and a mass may be palpable under the areola; If it is secondary to breast cancer, the affected breast may also have skin lesions such as orange peel and armor.
Prevention of nipple retraction
1. Pulling nipple: If there is nipple retraction in direct relatives such as mothers and aunts, it should be a key prevention target. After birth, mothers can gently lift the baby girl's nipples outward 1-2 times a day for girls with genetic predispositions. The movements should be gentle and gentle, preferably experienced operators, which can effectively prevent nipple retraction.
