A slide scanner in each district lab, routing images to a pooled roster of pathologists including diaspora volunteers, could give a diagnosis in days instead of months; the gap is scale and financing.","summary":"The bottleneck for cancer diagnosis in much of Africa and South Asia is the pathologist, not the tissue sample. Whole-slide scanners now cost a fraction of what they did, and pathology images travel well. A national or regional network would standardise tissue processing at district labs, scan every slide, route to a shared roster of pathologists (including diaspora volunteers and partner institutions), and track turnaround time as the primary metric. Several pilot networks exist; the gap is scale and sustainable financing.","asOf":"2026-09-08","links":[{"label":"Lancet Commission on diagnostics","url":"https://www.thelancet.com/commissions/diagnostics"}],"tags":[],"related":[],"cancers":[],"sections":["diagnostics"],"technologies":["digital-pathology-ai"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-global-access","b-workforce"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"Districts connected to a telepathology network will reduce median biopsy-to-report time to under ten days from more than four weeks, with discordance on second review under 5%.","rationale":"Teleradiology built a global industry on the same logic.
