ABSTRACT
Ultrasound is the examination of choice to evaluate any palpable breast mass, being quick, painless and cheap, and having none of the risks of ionising radiation that limit the use of mammography in younger women. Ultrasound should be used to guide needle sampling of all palpable lesions, as it provides a lower rate of inadequate sample collection than clinically guided biopsy and has a much smaller risk of pneumothorax.
