I, nipple invagination nipple invagination, that is, the female nipple does not protrude from the surface of the areola or even sunken in the skin surface of the local crater-like phenomenon. The depth of nipple invagination varies and can be divided into three categories: one is partial nipple invagination: the nipple neck exists can be easily extruded after extrusion nipple size is similar to that of normal people. The second category is the nipple completely sunken in the areola, but can be squeezed out by hand nipple nipple is smaller than too little normal, mostly without nipple neck; the third category is the nipple completely buried in the areola below, can not make the inverted nipple extrusion. If you find nipple invagination female best timely correction, according to different sympathetic special situation to choose the next few methods: is the technique of pulling: the girlhood is an important period of breast development, is also an important period to correct nipple invagination, often pulling the nipple, can make both breasts protrude, the surrounding skin support increased, play a “shaping” role. The nipples will gradually bulge outward over time. If you can’t pull, you can push the skin of the breast near the nipple outward first. It is suction therapy: after pregnancy, the nipple is suctioned several times a day by applying a breast pump, using its negative pressure to induce nipple bulging. Is the use of nipple corrector is the treatment of flat or sunken nipples. Mammary hyperplasia Mammary hyperplasia is a benign disease rather than cancer. It is caused by the increase of estrogen level in the body, which causes the proliferation of glandular end milk ducts and alveoli and surrounding fibrous tissues in breast tissue with lymphocytic infiltration. Mastocytosis is divided into three types: 1. Breast pain: also known as breast tissue hyperplasia, characterized by periodic pain in the breasts, mostly seen in women aged 20-40, with pain related to the menstrual cycle, with obvious symptoms before menstruation and relief after menstruation. The correct method of examination breast can not feel the lump, most of them show local tissue thickening and diffuse distribution of granular areas, so it is also called swollen granular breast. Breast pain is mostly self-limiting and can be relieved after marriage and pregnancy, and no cancer will occur. 2. Breast adenopathy: Mostly seen in young and middle-aged women, it is often a limited lump with pain in one side of the breast, or bilateral, and the pain is related to the menstrual cycle. Most of them occur in the upper outer quadrant of the breast, the lump is small, about 1-3 cm in diameter, firm and not hard, and the boundary with the surrounding tissue is not clear. The early stage of mammary gland adenopathy is lobular hyperplasia with cobblestone sign. This fashion will not be cancerous, but there is a 1% cancer rate in the middle and late stages of mammary adenopathy. 3, cystic hyperplasia of the breast: common in middle-aged women, manifested as breast lumps, but a single larger lump, rounded, smooth surface, cystic or solid feeling. It can also be manifested as multiple cystic nodules in the breast. About one-third of patients may have pain and tenderness in the early stage, but it is not significant, and sometimes there is nipple discharge. About 3-7% of cystic hyperplasia of the breast can become cancerous, so it is necessary to be especially vigilant and visit the doctor regularly. Intraductal papilloma usually has no conscious symptoms, but is often noticed due to nipple overflow contaminating underwear. The overflow may be bloody, dark brown or yellow liquid. The tumor is small and often cannot be palpated. Occasionally, larger masses of large ductal papillomas can be found in the areola area as small nodules several millimeters in diameter, mostly round, soft and pushable, and light pressure on this mass often results in bloody fluid overflow from the nipple. The treatment is mainly surgical: for solitary intraductal papilloma, the lesioned ductal system should be removed, and the ductal opening should be correctly positioned before surgery. For older patients, simple mastectomy may be performed. The rate of malignant transformation is 6%-8%, especially for papillomas originating from small ducts. Fibroadenoma of the breast is common in young women and is related to estrogen. It is a single or multiple lumps in the breast, round or oval, with smooth surface, clear border, firm texture and slippery feeling. Although breast adenofibromas are benign tumors, very few have the possibility of malignancy, and the risk of such malignancy increases cumulatively. Therefore, most experts advocate that once diagnosed, surgery should be performed in principle. The effect of various kinds of medication is not reliable. When the endocrine environment changes rapidly during pregnancy and lactation, some adenofibromas will grow faster. Patients with this disease should have their tumors removed before marriage or at least before pregnancy.
