'A work of towering importance that will undoubtedly change science and save lives, but it will also change the way you see yourself and the people around you' Chris van Tulleken, author of Ultra-Processed People 'A groundbreaking, brilliantly argued book that debunks the myth that illness is the great equaliser' Siddhartha Mukherjee First, do no harm: All doctors train under this ethos, but what happens when harm comes not from conscious actions, but unconscious bias? Then, do the research: - Black British women are four times more likely than white women to die during pregnancy or childbirth - In the UK, Black and Asian patients wait nearly a week longer for a cancer diagnosis than white patients - People of colour are three times more likely to live in very highly polluted areas of the UK In Systemic, science journalist Layal Liverpool unearths the shocking research and articulates the vital solutions to the potent health threat of racism in society, science and medicine. Across the world, in every country she has studied and in every area of medicine she has examined, people belonging to marginalised racial and ethnic groups disproportionately experience poor health outcomes - with people of colour often experiencing worse health compared with White people. From cardiovascular disease to viruses, cancer to mental illness, Liverpool delves into the reasons racial health disparities exist and reveals that diseases are not 'great equalisers' - not when you live in an unequal society. She shows how the widespread adoption of anti-racist medical standards and societal policies will be central in creating a healthier world for everyone.
