Patient: Before menstruation, the swelling of the right external inferior fibroadenoma of the breast was felt significantly. Description of laboratory and ultrasound: Scattered hypoechoic strips in the glandular tissue of both breasts are interconnected and locally fused into a mass. The right breast is 10*6 mm, and the outer lower 25*13 mm hypoechoic area with clear borders and no obvious blood flow signal. Ultrasound suggestion: bilateral breast mastopathy, right breast fibroadenoma, US BI-RADS grade 3 None 1. Treatment recommendation 2. “Localized fusion into a mass.” Does it refer to the possibility of the presence of other fibroids? 3.What does “US BI-RADS grade 3” mean? Qin Yuenong, Department of Breast Medicine, Shanghai Longhua Hospital: Breast fibroadenoma is the most common benign breast tumor in young women, with a high incidence in the age group of 18 to 35. Breast fibroadenoma will grow gradually, but the growth rate varies greatly among individuals. Fibroadenomas larger than 10 mm usually require surgery. Surgery can remove the lesion directly and also obtain a pathological diagnosis. Because the ultrasound indicates an “external hypoechoic zone of 25×13mm”, such fibroadenomas are considered large and medication is not effective. The “local fusion into a mass” is not necessarily a fibroadenoma, but also a mastopexy nodule. From your ultrasound description “scattered hypoechoic bands …… local fusion into a mass” should be considered Mammary hyperplasia; fibroadenoma can be seen as “envelope” on ultrasound. “US BI-RADS grade 3” is described in a new article on my website. Patient: 25*13 adenoma. The doctor did not recommend minimally invasive because it was only 1mm away from the skin. Since it is bound to leave a scar, I am considering not having surgery at this time. And 1. ultrasound every three months. 2. organic vegetarian diet. 3. more exercise. Qin Yuetnong, Department of Mammary Gland, Shanghai Longhua Hospital: Fibroadenomas that have formed generally do not shrink. Doctors suggest to remove it before preparing for pregnancy, because abnormal fluctuation of hormones during pregnancy and lactation will stimulate the rapid growth of adenoma. At present, it can be closely observed by ultrasound. If there is a tendency to continue to grow, surgery is still advisable, after all, the larger the mass, the larger the incision. In your case, minimally invasive surgery is indeed inappropriate.
