There is no medical classification for breast fibroids, which can be a clearly diagnosed breast nodule. According to the BI-RADS grading criteria usually used for breast nodules, which can be divided into six categories according to the BI-RADS grading, breast fibroids grade 3 may refer to BI-RADS category 3 in the classification of breast nodules, which is generally not serious from a pathological point of view. Breast BI-RADS category 3 suggests that breast fibroids may be benign and the likelihood of malignancy is usually <2%, but they may still form sarcomas or appear malignant, and active surgical treatment is recommended if the indications for surgery are met. In addition, if breast fibroids compress the milk ducts, causing local pain in the breast or other indications of discomfort, you should also actively go to the hospital for relevant examinations and let the doctor determine whether surgery is needed.1. Strong blood flow signal: i.e. whether there is abundant blood flow in breast fibroids. If the blood flow signal is strong, it suggests that the blood supply may be richer and there is a possibility of malignancy, so surgery is recommended. If there is no blood flow signal or a breast nodule with little change in blood flow signal, regular observation is usually all that is needed. 2. Larger size: If the diameter of a breast fibroid is <1cm and the blood flow signal is weak, it can be observed first, but if significant growth is found, surgery may be required after consulting the doctor. In contrast, surgery is more recommended for larger sizes, with breast fibroids >1cm in diameter. Clinically, it mainly includes minimally invasive surgery and traditional surgery, and treatment can be chosen after consulting doctors; 3. More occurrence: Some patients presenting with breast fibroids can be solitary, and if they reach the surgical index, surgery is recommended, which usually has a better prognosis and is not easy to recur. However, some patients with breast fibroids can be multiple, and surgery is not recommended when the fibroids are small in size and large in number, and radiotherapy can be administered according to medical advice. Patients with breast BI-RADS3 should undergo regular checkups. Ultrasound of the breast can be reviewed every 3-6 months, and if breast nodules are found to be enlarged, or if there are changes in the edges of the breast nodules, surgical removal can also be chosen under the guidance of the doctor. In addition, patients with breast BI-RADS3 category should also pay attention to the routine in their daily life, and should also pay attention to dietary regimen. Try not to eat too stimulating and spicy food, and you can do outdoor activities and exercise appropriately, etc.
