Summarised results from each of the cited references |
All references show a greater sensitivity & specificity for ultrasound in the detection & classification of palpable breast masses and recommend its increased use as an adjunct to mammography in this clinical setting particularly in the x-ray dense breast or when the mammogram is negative in the presence of a clinical abnormality |

Statement (= the conclusion drawn from E) |
Not indicated in breast screening. Ultrasound recommended as an adjunct to mammography |

Comment (if any) to go in booklet version of MBUR5 |
Performed in the context of triple assessment at a specialist breast clinic (clinical examination, mammography/ultrasound & cytology/core biopsy) | |

Any other comments on this problem (e.g. caveats; suggestions for research or systematic review; cost or opportunity cost; users' views. |

Comments: Greater accuracy attributed to ability to diagnose lesions in x-ray dense breasts. Combination of mammo & ultrasound demonstrates 99% of palpable cancers
