A friend said: I am not fat, but a bunch of armpits but a bunch of flesh unsightly, what is it? Weight loss can be reduced? In fact, even very thin people, there will be side breasts, which can not be removed by exercise and weight loss, this is why? The parametrium appears in the fetal period and is a congenital oddity. In a few women, the excess mammary glands do not degenerate or degenerate incompletely in adulthood, an abnormality also known as polymastia, vagal mammary glands, extra mammary glands, etc. It can occur unilaterally or bilaterally. Medical theory suggests that the parametrium is often underdeveloped tissue, mostly resembling a baby’s breast, or only a skin pigmentation is seen, which may have a little skin thickening, resembling a tiny nipple. Some have only mammary glands and some have only nipples, but there are also complete breast bodies (nipples, areolas, and glands) that are visible in the armpit and are larger. The parametrium is also painful and swollen before menstruation and increases significantly during pregnancy, and those with nipples even secrete milk during prolapse. So what is the need for surgical removal of the parametrium 1, parametrium as a multiple breast deformity, affecting the appearance; for the larger anterior axillary parametrium affects the aesthetics, dress, and patients have urgent surgical requirements, can receive parametrial surgery treatment. 2.If there are obvious hard nodes inside; if there are parametrial fibroids, nipple overflow, obvious swelling and pain of the lump, and if there is a certain possibility of malignant change; if the lump has increased significantly recently, parametrial surgery can be considered. 3.Significant pain symptoms; pain symptoms affect the patient’s life. 4. Those with parametrial fibroids or nipple overflow should be treated with parametrial surgery. 5.If the diagnosis is unclear, those who cannot exclude other tumors can use parammary surgery for the improvement of parametrial breast. Paramastectomy surgical incision can be hidden in the armpit, plastic surgery to minimize the length of the wound, with fine plastic suture technique for suturing, the wound is hidden, generally not easy to see.
