How is ultrasound used in the detection of breast cancer?

Answer: Ultrasound is almost exclusively used as a diagnostic tool to perform a targeted study, meaning to evaluate a specific location in the breast based on an abnormality seen by mammogram or MRI. It can also be used to assess a site of pain or a palpable lump. It is an excellent tool for differentiating solid masses from fluid filled cysts, something that a mammogram can’t do. it is also the preferred tool for image guided biopsy, as it is far easier to use ultrasound than either MRI or mammogram when sampling tissue.
