Global evidence is only useful when everyone is represented.
African populations remain underrepresented in cancer biomarker datasets. OACBDA closes that gap by making region-specific findings easier to discover, compare, and build upon.

OpenFree to explore and designed for shared progress.
02
ContextualEvidence stays connected to population and geography.
Why OLS exists
Africa should not be an afterthought in the evidence.
Locally led research, structured context, and open discovery can help make cancer science more representative and more useful.
Explore the evidence
Start with a marker.
Follow the context.
Search by biomarker, cancer type, or country. Sort, filter, inspect and export the prototype records to test a complete discovery workflow.
