Human beings have two breasts on the chest, but some people also have two breasts in the armpits, which is called paratits. Humans are mammals, and mammals are born with multiple breasts. Humans have 6-8 pairs of mammary gland embryonic base during the fetal stage, and by the time they are born, only one pair on the chest is left, and the rest are all degraded. However, in some cases, the degradation of the mammary gland embryonic base is incomplete, and paramastia will appear after birth. There are reports that the chances of cancer caused by the secondary breasts are higher than those of normal breasts. Expert support: Zhou Ling (a pseudonym) in her 30s, after giving birth to a child, developed two egg-sized lumps under each armpit, which felt soft to the touch. She thought she had some kind of tumor, and rushed to the hospital for an examination, where the doctor said that she had paratesticular breasts, that is, breast-like tissues that had grown up outside of her normal breasts. Some doctors suggested that Zhou Ling through surgery to remove the paratits, but Zhou Ling’s mother said to her: “paratits are not a disease, just a useless structure of the human body, in addition to affecting the aesthetic appearance, the body is not a big problem, do the surgery will always hurt the energy, and then married and have a child, it is not worth it to get a knife for the aesthetics again.” Zhou Ling could not make up her mind. The paratits are caused by incomplete degeneration “The paratits are first of all a congenital developmental abnormality, which is hereditary.” “Right, right, right, my mom has them too!” “Most mammals have multiple breasts. In humans, during fetal life, there are six to eight pairs of mammary embryonic bases in the two milk lines from the armpits on both sides all the way up to the groin, and by the time they are born, the rest of the mammary embryonic bases usually gradually regress after the ninth week of the embryo, except for one pair on the chest which is preserved only. If the degeneration is incomplete, an extra breast will form after birth, medically known as the paratesticular breast.” The secondary breast is smaller than the normal breast; in some cases, the nipple, areola, and gland are present; in others, there is only breast tissue without a nipple, and in still others, there is simply a small, underdeveloped nipple with no breast tissue. They are commonly found in the armpits or in the upper or lower part of the normal breast, and most often occur bilaterally, but also unilaterally. Very few people also have the presence of paratits in the abdomen and groin. According to statistics, the incidence of paratits is 2%~4%. It occurs in both men and women, with a ratio of about 1:5. Generally, paratesticular breasts are painless and itchy, and some of them have a feeling of distension or pain before menstruation, and the feeling of distension and pain disappears after menstruation. The nipple of the paratesticular breast can also secrete milk during breastfeeding, and the nipple of the paratesticular breast is mainly localized swelling and bulging, when touching with hands, you can feel a lump under the skin with the same hardness and elasticity as the normal breast mammary glands, and the boundary is not clear. The paratesticular breasts with breast tissue tend to enlarge, swell and hurt during puberty, pregnancy or breastfeeding, along with the development of normal breasts. Abnormalities occur in the secondary breasts and should be operated as early as possible “You belong to the type with breast tissue, which is felt as a stripe inside. The paratesticular breast with breast tissue is also affected by endocrine as normal breast, and can occur the same diseases as normal breast, such as mastitis, breast hyperplasia and benign and malignant tumors. Moreover, there are reports that the chances of cancer caused by paratesticular breasts are higher than that of normal breasts, so it is more important to be alert to paratesticular breasts with mammary tissues, and once there is a lump, it gets bigger, it becomes painful, and there is a hard nodule, you should seek medical treatment in time and consider surgical excision in order to avoid the occurrence of secondary lesions and cancer.” Paramastectomy can be performed on an outpatient or inpatient basis. Outpatient surgery usually uses local anesthesia, such as in the armpit, the doctor will be along the armpit crease under the knife, the wound is hidden, does not affect the wearing of suspenders in the future, and the stitches can be removed after 7 to 10 days. The accumulation of fat in the armpits is not paratits For some people think that wearing underwear improperly will also cause paratits, Wang Ximei explained that this is a misunderstanding of the concept of paratits, that can only be called fat accumulation, is in the armpits and breast tissue between the accumulation of some excess tissue. These accumulations of fatty tissue are mostly caused by long-term incorrect underwear wearing habits, due to too small bras, steel rings, cups relatively insufficient coverage, long time extrusion, resulting in fat accumulation, it can be improved through exercise, liposuction and other methods, but the real paratits can not be eliminated through these methods. For these fat accumulations, they can be improved in the following ways: 1, choose the right size of underwear to choose the correct size of underwear, it is very important to try on when purchasing, do not just buy based on the size, because there are differences in the specifications of underwear sizes of different brands, so be sure to try it on when purchasing. 2, correct wearing. Leaning forward to the upper body will be the bra cover, buckle the back buckle, adjust the shoulder straps, and then left and right hands were dialing breasts, the armpit fat, the lower bust breasts dialed into the cups. 3, sports massage. You can expand the chest movement, thin arm movement, the use of chest muscle and arm muscle groups contraction, driven to improve the accumulation of fat.
