Digitise the nation's pathology slides and link them to outcomes

Pathology departments hold decades of glass slides with matched registry outcomes. Digitising them at scale (tens of millions of slides) and linking to registry survival, treatment and recurrence data would create a public resource that dwarfs any commercial pathology AI training set. Precedents include the PathLAKE and iCAIRD centres in the UK, the TCGA image collection, and the NHS digital pathology programme. Cost is dominated by scanning and storage, both of which have fallen sharply.
