You don’t need to have an empty stomach to have a breast ultrasound. If you usually feel breast swelling and pain, discomfort, or if you touch a hard lump inside with your own hands, you should go to the hospital for an examination. You can eat or drink water, and you can check in the morning or in the afternoon, there are no special requirements. At present, color ultrasound is the most common method of examining the breast. When examining the breast, color ultrasound can clearly show the hierarchical structure of the breast, and can basically confirm the diagnosis of the more common breast diseases, such as breast cysts, septic mastitis, breast fibroids, breast duct tumors and hyperplastic nodules; the detection rate of breast cancer is also very high, and it is recommended that women have a breast checkup once a year. If problems are found, the frequency of examination should be increased. Ultrasound examination of the breast is very convenient, because there are no special requirements, the cost is more reasonable, and the localization of occupying breast lesions is very accurate, which provides great help to clinicians.
