Common tumors of female breast are divided into two categories: benign tumors and malignant tumors. Benign tumors: breast fibroadenoma, breast lipoma, intraductal papilloma, breast hemangioma, etc. Features of benign tumors: Mostly seen in adolescent or middle-aged women, single or multiple nodules, soft or tough, regular shape (round or round-like), smooth, and good activity. It is characterized by long course and slow growth. Special tests, such as ultrasound, often indicate hypoechoic nodules with clear margins, regular morphology, no blood flow signal, and no calcified foci. Mammogram can indicate low density nodules with clear edges and no obvious calcification. Second, malignant tumors of epithelial origin we call breast cancer (including various pathologic subtypes). Those of mesenchymal origin are called sarcomas. There is also the more rare malignant lymphoma of primary breast origin. It is mostly seen in women aged 35-55 years, but in recent years the age of onset is significantly earlier, with the youngest patient reported to be 7 years old in China and 3 years old abroad. In the early stage, the nodules are isolated and solitary over the breast, usually painless, hard, irregular, rough, and poorly mobile. In the middle and late stages, special signs such as “dimples” and “orange peel” may appear, nipple pointing changes or nipple overflow and nipple retraction, and pain may appear. Special tests such as ultrasound may indicate a single mixed echogenic nodule in the breast with irregular shape and burr-like margins, with clusters of calcifications and abundant blood flow in the nodule. The B-RADS classification is mostly grade IV or above. In conclusion: regardless of benign or malignant breast tumors, they should be treated actively, with appropriate surgical procedures and postoperative pathological diagnosis. Breast tumor is the most common type of breast disease among our inpatients, and the treatment method is mainly a comprehensive treatment based on surgery and supplemented by various other methods of treatment. Surgery for benign tumors tends to be minimally invasive and cosmetic. The trend of breast-conserving surgery for early malignant tumors is beginning to emerge, and we are actively carrying out stage I reconstructive surgery and stage II reconstructive surgery after radical breast cancer surgery to minimize the trauma to the patient’s appearance and psychology.
