Fibroadenoma of the breast is the most common type of benign breast tumor and is more common in young women and less common in premenstrual and postmenopausal women. It is believed to be associated with relatively or absolutely elevated estrogen levels, hypersensitivity of breast tissue to estrogen, and dietary and genetic factors. The most common reason for a visit for breast fibroadenoma is a self-reported breast lump. Most lumps occur in the gland-rich outer upper quadrant and are often solitary, but can also occur in multiple bilateral breasts. The masses are often tough, well-defined and mobile, and the surface of the mass is relatively smooth. However, if the lump grows in the rich glands, the boundary of the lump is often felt to be less clear and more fixed. If the lump is completely covered by glands, the local glandular thickening can be felt only during physical examination. Gong Xuchu, Department of Surgery, Nantong Hospital of Traditional Chinese Medicine Initial differentiation of the benign and malignant nature of the masses. Typical lumps of breast fibroadenoma are not difficult to distinguish. Such solid lumps do not change with menstrual cycle, and the growth rate of lumps is slow, and the diagnosis can generally be confirmed after careful physical examination by an experienced breast specialist. However, if the lump is encapsulated by the gland and is deeper, and if the patient also suffers from cystic hyperplasia, mammography and ultrasound are often needed to make a clear diagnosis. In clinical work, to avoid underdiagnosis of malignant tumors, a triple examination of breast lumps is often used: clinical examination, imaging, and puncture biopsy. patients with an MTTS score of 5 need to undergo surgical precision biopsy. Fibroadenoma of the breast is treated primarily by surgery. However, for patients with younger age, smaller lumps, and benign tumors clearly indicated by triple examination, conservative treatment or follow-up can be recommended. Chinese medicine methods such as dredging liver and Qi, activating blood circulation and resolving phlegm have definite efficacy in balancing the endocrine level of human body, which has the effect of inhibiting and delaying the growth of fibroadenoma. However, in this process, it is important to pay attention to observation, grasp the timing of surgical treatment, and give correct advice to patients. For the following cases, prompt surgical treatment is recommended: 1. The patient strongly requests surgery to clarify the nature of the pathology. 2.The mass increases significantly during a particular follow-up visit. 3. The mass is found before the non-pregnant woman plans to become pregnant, or at the time of pregnancy. Pregnancy and breastfeeding may lead to tumor growth or even malignant transformation. To avoid breast lumps during pregnancy, which makes diagnosis and treatment difficult, surgery is recommended. 4.Patients with high risk factors of breast cancer and clinical need to clarify the pathological nature. 5.Patients with applied MTTS score greater than or equal to 5. 6.Patients who are over 35 years of age. 7.Other cases considered necessary by breast specialists. With the advancement of medical technology, the surgery of breast has been done more and more delicately. Specialists usually decide different surgical incisions according to the different parts of the tumor. Tumors near the areola can be treated with an arched incision around the areola and intradermal sutures to close the incision so that the scar is not easily detectable after the wound recovers. For tumors in the lower part of the breast, a curved incision can be made along the lower edge of the breast for a more concealed wound. In young patients, if the tumor is less than 3cm, minimally invasive surgery such as McMurdo’s minimally invasive rotational incision, which is usually made in the more concealed part of the breast edge with a tiny incision of about 3mm, will leave almost no scar after surgery.
