Parametrium is an extra breast in the body that is brought out from the embryo and not formed later in life. When the embryo grows to almost 9 mm, there are 6-8 pairs of mammary gland primordia in the breast line from the armpit to the groin, only one pair of these primordia will be preserved in the chest and eventually evolve into a breast, the rest will degenerate. If the degeneration is incomplete, a parametrium is formed, and therefore the parametrium carries breast tissue. Theoretically, there are three forms of parametrium: (1) with mammary tissue without nipple. (2) Nipple without mammary tissue. (3) With nipple and breast tissue. However, in practice, most women have a mixture of mammary glands and fat. The normal mammary gland extends a little bit in the armpit, but it varies from person to person, some people have more, some have less. Generally speaking women who are fuller will have slightly more mammary glands in their parametrium. Where there is glandular tissue in the parametrium, it is affected by the same sex hormones as the normal breast, with cyclical changes, premenstrual swelling and pain, and also the same common diseases as the normal breast, such as hyperplasia, cysts and parametrial cancer. If your parametrium swells and hurts with menstruation and even grows nipples, it means that the main component in the parametrium is the mammary gland, and this type of parametrium needs to be addressed surgically. In fact, most of the examples with mammary glands in the parametrial breast are actually not common, and most of the parametrial breast in the population is mostly composed of fat. If it is soft and fatty to the touch, and there is no periodic change in size or pain, it is considered to be mainly fat, and many people call it “pseudo-parametrial”. Of course, if you think you can’t tell them apart accurately, it is recommended to go to the hospital for ultrasound to identify them. Since most of the “pseudoparasites” are fat, where does this fat come from? Why does it accumulate in the armpits? In fact, the causes of pseudo-parametrics are basically the following three points: a. Poor posture Often chest, hunchback, shrugging shoulders, etc., will lead to the accumulation of fat in the armpits, the formation of “pseudo-parametrics”. In addition to poor posture, it is also common for obesity to produce “pseudo-parametric” cases. Obesity leads to excess body fat, fat will naturally be hoarded in various parts of the body, armpits, of course, can not escape. The long term wearing of ill-fitting underwear or overly tight tops will cause pressure on the chest, easily pushing the meat that belongs to the chest to the armpit, thus forming a “pseudo-parametric”. Since it is the fat that causes the “pseudo” side breast. Then it is possible to solve the fat. The first step is, of course, liposuction. Liposuction for the removal of parametrial breast is a local liposuction, the operation is relatively simple, the surgical incision is about 0.5 centimeters, the trauma is relatively small, the operation is the application of swelling anesthesia technology. Minimally invasive liposuction to remove the parametrial needs to squeeze the accumulated blood and residual fluid after surgery, the surgery does not affect the normal work and life, and the wound can recover completely in a week.
