In fact, many women have problems with parametrium, which is a raised breast-like tissue that usually grows in front of the patient’s armpit. Many women suffer from the problem of parametrium, mainly because it greatly affects the appearance of beauty, in the fall and winter when wearing more clothes, but in summer when wearing thin clothes parametrium patients will be more troubled. The effect of aesthetics is only one of the adverse effects of the secondary breast, if there is breast tissue in the secondary breast, then there is a risk of lesions if not properly cared for, so you should find some effective ways to treat it. 1. Fully developed parametrium: There are fully developed breast gland tissues. It is affected by estrogen, swollen and even slightly painful with the menstrual cycle, and disappears after menstruation. During pregnancy, the parametrium also swells with the development of the breast, and milk can be discharged from the parametrium during lactation. After weaning, they become softer and the mammary glands shrink. Since multiple nipples or breasts also have a chance of developing breast cancer, they can be treated by surgical removal. However, smaller patients with polybreast with no obvious symptoms can be treated without treatment. If the gland is gradually enlarging, painful and uncomfortable, or if abnormal lumps are found in the parametrial gland that are suspected to be accompanied by tumors, or if there is a family history of breast cancer, or if the parametrial breast is obviously elevated, the nipple is enlarged, or the areola pigmentation affects the appearance, surgery is needed. 2. Incompletely developed parametrium: It can be a parametrium with only incompletely developed breast tissue without nipple and areola, or with only pigmentation as areola and local skin thickening as nipple. There are also cases of infantile nipples without areolas or hyperpigmented areolas without nipples and mammary glands. Those with underdeveloped breast tissue may also experience swelling and pain with menstruation. Those with areola only or nipple only do not show this. In a few cases, the paramammary glands are connected to the normal breast and empty their secretions into the normal breast, but most of them are separate and are not connected. Treatment 1.The fully developed parammary gland and incomplete parammary gland can be surgically removed if they have periodic pain or irregular pain during menstruation, pregnancy or lactation, which obviously affect the patient’s health. 2.If the volume of the parametrial gland affects the inward movement of the upper arm and appearance, it can be surgically removed. 3.If malignant change is suspected and cannot be distinguished from tuberculosis and other lesions, excision is appropriate. 4. All suspected paramammary tumors should be removed. For patients with parametrial breast cancer, the normal breast should be excluded from cancerous changes; the surgical procedure is radical surgery to remove the parametrial breast cancer on the affected side and the normal breast on the corresponding side, and the axillary lymph nodes on the same side are routinely removed. Depending on the location of the parametrial breast, radiotherapy and chemotherapy are routinely administered after surgery. Regular and close observation of both breasts, especially the ipsilateral breast, should be paid more attention. 5.For parametrial breast cancer in the caudal part of the breast, depending on the situation, segmental resection of the outer upper quadrant of the ipsilateral breast or simple mastectomy with axillary lymph node removal, postoperative radiotherapy and chemotherapy will be performed.
