Fibroadenoma (Fibroadenomas) (International Standard Classification of Diseases (ISCD) code D24) is a common breast mass in women during their reproductive years, the incidence of which decreases with age, and occurs most often before the age of 30 years, with a small proportion occurring after menopause. Main clinical manifestations: a painless, hard, mobile and isolated solid mass can be detected on the breast. Generally, the growth is slow and the size is mostly within 3cm, but there are some cases that show hormone-dependent characteristics. I once met a 22-year-old female patient, who was only the size of a peanut before pregnancy, and then grew up to the size of a tomato in the third trimester of pregnancy. Fibroadenoma itself is a benign tumor, clinical mainly to identify and breast cancer, examination methods: hand model, ultrasound, molybdenum target and pathology biopsy, fibroadenoma ultrasound generally do not see the blood supply, the border is smooth and clear, there is no calcification, while breast cancer is often the opposite. Fibroadenomas have a low rate of malignancy, so clinical observation is an option for most. Oral omeloxifene (ormeloxifene) has been reported to be effective, I have not used this drug so I cannot comment on it, but this type of hormonal drug is better not to take. Certain domestic proprietary Chinese medicines have also not been seen to be effective, and it is also recommended not to take them, which is a waste of money. If during the observation period, the growth is relatively fast, the examination has the possibility of malignant changes, more nervous, have a family history of breast cancer, etc., or recommended surgery to deal with, at present there are the following 2 methods, can be chosen, are not too traumatic. 1.Localized ablation, there are radiofrequency, freezing, microwave, ultrasound focusing and other methods, less traumatic, not open the mouth. However, the possibility of malignant tumor must be ruled out by fine needle biopsy before ablation. There are three conditions for ablation: (1) ultrasound can be seen; (2) clear diagnosis through pathological examination, and can exclude malignant tumor of breast; (3) the diameter of the lump is not more than 4cm. 2, surgical excision under local anesthesia, this surgery is also very small, trauma is not big, there is no more than a small surgical incision. For fibroadenoma, the surgery can not only remove the tumor, but also need to remove a little bit of the surrounding normal breast tissue, the border has 3mm can be. No local recurrence has been found after complete removal.
