Three validated computer simulation models — indicate that providing post mammography ultrasounds for dense tissue breasts — is likely to be too expensive and arguably too harmful — when balanced against — (a) preventing only 0.36 cancer deaths per 1,000 women screened — and — (b) the unnecessary extra 354 biopsies per 1,000 women screened Comments Off
