Breast disease is a common disease among women. Breast cancer accounts for the first or second highest incidence of malignant tumors in women. Breast cancer is not preventable, so how to detect and treat it early is the key to cure it. Breast diseases are divided into four categories: i. Congenital malformations: multiple nipples, multiple breasts, i.e. parametrium. ii. Acute mastitis: Most of them are maternal, most of them are in the first trimester and occur 3-4 weeks after delivery. Third, cystic hyperplasia of the breast: referred to as mastopathy, related to menstruation. Breast tumors: breast fibroadenoma, intraductal papilloma, breast sarcoma, breast cancer. Most of the treatments for various breast diseases need to be based on surgical treatment, or to obtain tissue for pathological examination after surgery to make a clear diagnosis before targeted treatment, avoiding blind treatment to avoid aggravating the disease or delaying treatment, the role of Lin Daiyu in the TV series “Dream of the Red Chamber”, without a clear diagnosis of breast tumor, a conservative treatment, delaying the disease and losing the opportunity to cure, so early Early detection, early diagnosis and early treatment are the keys to cure breast cancer. The conventional methods to diagnose breast diseases include, firstly, breast self-examination or breast examination by a specialist, finding problems, ultrasound examination, breast fluoroscopy, X-ray mammography; all the above examinations can only make a preliminary diagnosis, for the diagnosis of breast tumor diseases there must be pathological examination results, so how to obtain breast tissue for pathological examination is the key to confirm the diagnosis of breast diseases, traditionally The traditional methods of fine needle aspiration biopsy, open surgical excision or partial excision of lump biopsy are used. Fine needle aspiration biopsy has less tissue, low positive rate, and the lump still needs to be surgically excised again after biopsy; open surgical excision or partial excision of lump biopsy will cause greater damage and leave obvious 3-5 cm surgical scars on the breast, which affects the beauty and aesthetics, with high surgical risk and long treatment time. .
