B ultrasound is a means of initial screening for breast cancer, detecting abnormalities but not fully confirming the diagnosis.
The initial screening tool for women with breast cancer is color Doppler ultrasound (B ultrasound), but color Doppler ultrasound (B ultrasound) is used as an initial test to check for breast cancer but does not provide a final diagnosis of breast cancer.
Typical signs of breast cancer include: a lump in the breast, with the majority of breast cancer patients having a localized lump as the first diagnosis; bilateral or unilateral nipple discharge; pathological changes in the skin of the surrounding soft tissue, with a depression in the breast skin; abnormalities in the shape of the nipple and areola, either bilaterally or unilaterally; and enlarged axillary lymph nodes. All of the above are obvious features of breast cancer, so it is said that color Doppler ultrasonography (B-ultrasound) can detect abnormalities. However, there are many reasons for the patient to have a lump or mass and a small or large amount of nipple overflow during the examination. We cannot blindly characterize and confirm the diagnosis by these features alone, but must combine with other adjuvant techniques in order to characterize (radiological mammography, fine needle swelling aspiration cytology).
