Breast ultrasound can detect the more common breast diseases, such as breast cysts, purulent mastitis, breast fibroids, breast duct tumors and hyperplastic nodules. If you usually feel breast swelling and discomfort, or if you touch it with your own hands and feel a hard lump inside, you should go to the hospital for examination, and the preferred item is color ultrasound; because there are no special requirements for color ultrasound, you can eat or drink, and at present, color ultrasound is the most commonly used examination item to check the breast. Color ultrasound can clearly show the hierarchical structure of the breast, and it is recommended that women should have a breast checkup once a year. If a nodule is found in the gland with an irregular shape and unclear edges, and a hard lump is found to be less mobile when palpated, with no obvious demarcation from the surrounding glands and a harder texture, it is time to be alert and it is best to perform a puncture for pathological examination. Ultrasound examination of the breast is very convenient, the cost is more reasonable, and the localization of occupying breast lesions is accurate, which provides great help to clinicians in surgical treatment.
