Medical practitioner – Negligence. The claimant sought damages for alleged clinical negligence, resulting in a delayed diagnosis of *** cancer. The Queen's Bench Division, in dismissing the claim, held that the defendant's consultant *** surgeon, who had seen the claimant at an appointment in March 2011, had not been negligent in her management of the claimant, who had eventually been diagnosed in 2013. The court preferred the interpretation of the national guidelines contended for by the defendant's expert, and found that he represented a responsible body of medical opinion that would not have performed a biopsy in the circumstances that had existed in March 2011.
