Nipple invagination is invisible to outsiders, and it is uncomfortable for women to appreciate themselves. More importantly, nipple invagination itself is a kind of breast malformation, and some even are external symptoms of malignant tumors on the breast. Before puberty, women's breasts are undeveloped and their nipples are very small. After puberty, with the change of hormone level in the body, menstruation comes, breasts begin to develop, and nipples gradually increase and protrude. Although the nipples of unmarried women and pregnant women are small, they all protrude from the areola plane; If part or all of it is lower than the areola plane, or even sunken in the opposite direction, it will be trapped under the skin surface and form a local crater shape. This condition is nipple invagination (nipple depression).

In particular, some girls are shy about breast development, so they wear tight underwear to tighten their breasts, or wear a bra that is too small too early, and the developing breasts will be squeezed and flattened; At the same time, the poor blood circulation and insufficient nutrition supply of the oppressed breast will affect the normal development of the breast; The nipple is also deeply immersed in the breast due to being squeezed, forming nipple invagination (nipple depression).

Nipple invagination (nipple depression) varies in degree, and some only show nipple invagination, and the most serious manifestation is nipple invagination or even inversion. Clinically, nipple invagination can be divided into three types:

Type I: The nipple is partially invaginated and the nipple neck exists. The invaginated nipple is easily squeezed out by hand, and the size of the squeezed nipple is similar to that of ordinary people;

Type Ⅱ: All nipples are depressed in areola, but they can be squeezed out by hand. Nipples are smaller than normal, and most of them have no nipple neck.

Type ⅲ: The nipple is completely buried under the areola, and the invaginated nipple cannot be squeezed out. Nipple invagination (nipple invagination) not only hinders the beauty and lactation function of the breast, but also is difficult to clean locally. The concave part is easy to hide dirt and accept dirt, which often causes local infection. The mammary duct is connected with the concave part, and inflammation can spread to the breast, causing mastitis.

Nipple invagination (nipple depression) is mainly congenital, but it can also be caused by trauma or surgery, breast tumor and fibrous hyperplasia after mastitis. Congenital nipple invagination is caused by poor development of smooth muscle of nipple and areola. These muscle fibers are pulled inward, and the lack of supporting tissue under the nipple forms nipple invagination. Generally, both sides occur at the same time, but also unilateral onset. The invaginated nipple can come back after being slightly squeezed or pulled, which belongs to mild nipple invagination. Congenital nipple inversion is more common in women who have no history of breastfeeding.

Secondary nipple invagination is common in breast diseases, such as breast cancer, often unilateral invagination. Don't underestimate the acquired nipple invagination (nipple depression). You should go to a specialized hospital and do relevant tests, such as B-ultrasound and X-ray mammography, to rule out the possibility of breast cancer. There is another situation: eczema and itching around the nipple appear repeatedly and last for a long time. We should consider the possibility of paget's disease, which is a special type of breast cancer.

Correction and prevention of nipple depression

Straight breasts are the focus of women's beauty, and nipples are the "delicate points" in the focus. If nipple invagination (nipple depression) is found, women had better correct it in time. The following methods can be selected according to different situations.

The first is manual pulling. Adolescence is an important period of breast development and correction of nipple invagination. Often pulling the nipple can make the breast protrude, increase the supporting force of the surrounding skin, and play the role of "shaping". Several times a day. After a long time, the nipple naturally protrudes outward. If you can't pull it out, you can first push the skin near the nipple of the breast outward.

The second is suction therapy. After pregnancy, use a breast pump to suck the nipple several times a day, and use its negative pressure to expand the nipple.

Third, the use of nipple orthosis is to treat nipple flattening or depression.
