Dalton v Southend University Hospital NHS Foundation Trust
[2019] EWHC 832 (QB)·2019·Liability decided at trial
A 38-year-old woman with a hard breast lump had a mammogram and ultrasound that looked benign and was discharged without a biopsy; cancer was found in 2013. Yip J accepted that a responsible body of breast surgeons would not have biopsied on those findings.
Triple assessment does not always require a biopsy where imaging is reassuring. A later cancer diagnosis does not by itself prove the earlier clinic decision was negligent.
