Breast lump is one of the three main symptoms of breast disease (breast pain pain, breast lump, nipple overflow). In recent years, the incidence of breast diseases that plague women has been rising year by year, especially breast cancer, which is one of the most common malignant tumors in women. Although China is a low incidence area of breast cancer, the incidence rate is rising year by year, and in recent years, it has jumped to the first or second place of female malignant tumors in some big cities in China, and the age of onset is also tending to be younger, and its development and harm can not be ignored. Because of this, the correct management of breast lumps is particularly important. Most breast diseases require surgical treatment, which requires breast surgeons not only to have rich theoretical knowledge and skillful surgical techniques, but also to have a discerning aesthetic sense, not only to not affect the function of the breast, but also to maintain the position and shape of the breast as a sex organ by the standard principle of aesthetics, and to minimize the formation of postoperative scars in order to achieve good aesthetic effect after surgery. Our department carried out transnipple areola complex excision of benign breast lumps in 2008, which is praised by patients for its small surgical incision, little damage, no aesthetic effect and no effect on breastfeeding. This surgery is mainly suitable for 1, breast adenopathy 2, breast fibroadenoma 3, plasma cell mastitis 4, breast cysts and other benign breast lesions and some patients who refuse ultrasound-guided minimally invasive rotational excision of breast masses.
