Fibroadenoma of the breast is a mixed tumor of fibrous tissue and glandular epithelium that occurs in the lobules of the breast and is the most common type of benign breast tumor. Breast fibroadenoma can occur in women of any age after puberty, but it is more common in young women aged 18 to 25. The disease is associated with endocrine hormone imbalance, such as relative or absolute elevation of estrogen can cause the disease. The main clinical symptom is a painless breast lump, which is rarely accompanied by breast pain and nipple discharge. As to whether fibroadenoma of the breast can become malignant, it is generally believed that in a few cases, sarcomatous transformation of the fibrous component can occur, while in very few cases, cancerous transformation of the epithelial component occurs. Fibroadenoma of the breast is called “nucleus pulposus” in Chinese medicine. In the past, it was also called “breast fetish”, so the “breast fetish” seen in many TCM books refers in part to mastocytosis and in part to fibroadenoma of the breast. In order to avoid confusion in the naming of the two, it has been standardized to the category of “breast nucleus”. According to Chinese medicine, breast nodules are caused by liver qi stagnation or blood stasis and phlegm clotting. According to the book of Surgery, nodules in the breast are “like plums and plums, although they are superficial, they are also the gradual transformation of breast rocks”, recognizing that a few nodules in the breast may become malignant over time. The most effective treatment for mammary fibroadenoma is surgery. Surgery can remove the adenoma and cure it, but in some cases it can recur at the original site of surgery or regenerate in other parts of the breast. According to traditional Chinese medicine, herbal medicine can adjust the endocrine status of the body and eliminate the lumps in the breast, which can achieve better results in treating adenomas.
