Breast HealthBreast ultrasoundUltrasound works by sending high-frequency sound waves into the breast. The pattern of echoes from these sound waves is converted into an image (sonogram) of the breast's interior. Ultrasound, which is painless and harmless, can distinguish between tumors that are solid and cysts, which are filled with fluid. Sonograms of the breast can also help radiologists to evaluate some lumps that can be felt but are hard to see on a mammogram, especially in the dense breasts of young women. Unlike mammography, ultrasound cannot detect the microcalcifications that sometimes indicate cancer, nor does it pick up small tumors.
