I thank the Minister for her answer, and for her positive response during a recent Westminster Hall debate on this issue. My constituent Trevor Jones died in September last year from glioblastoma. Samantha, his widow, learned later that life-extending treatment options might have been available had his brain biopsy not been stored in paraffin blocks but instead flash frozen. Will the Minister recommit to examining how flash freezing can be made standard practice for brain biopsies across the NHS?
