Bias in the way medical research is carried out means that new medicines for diseases such as cancer – as well as the tools used to diagnose patients with some conditions – are disproportionally tested on people of European heritage. This can lead to those not represented in the data being misdiagnosed as well as some treatments not working as well as they should.

From the Ghanaian scientist helping to develop cancer treatments which work better for African people, to the team in England using AI to diagnose dementia in communities where English isn’t widely spoken, in this programme we will meet the solution-seekers trying to make healthcare more equal.
