The claim that Black men have double the risk of being diagnosed with and dying from prostate cancer is strongly supported by multiple authoritative sources. A peer-reviewed study published in BMC Medicine (2015), using Public Health England data from 2008–2010, found that the lifetime risk of being diagnosed with prostate cancer was approximately 1 in 4 (29.3%) for Black men compared to 1 in 8 (13.3%) for White men, and the lifetime risk of dying from prostate cancer was approximately 1 in 12 (8.7%) for Black men compared to 1 in 24 (4.2%) for White men. The study explicitly concluded: "Black men are at double the lifetime risk of both being diagnosed with and dying from prostate cancer, compared to White men in England." Prostate Cancer UK, the leading charity in this domain, states on its website: "1 in 4 Black men will get prostate cancer. That's double the risk of other men." More recent analysis by Prostate Cancer UK (using data from March 2021 to January 2023) confirms that Black men continue to have the highest prostate cancer mortality rates, with Black Caribbean men 1.73 times more likely to die than white British men and Black African men 1.28 times more likely — noting "up to twice the lifetime risk of dying from the disease compared with white men." The core assertion — that Black men face approximately double the risk of both diagnosis and death from prostate cancer — is directly supported by peer-reviewed research and by the UK's principal prostate cancer charity. The "double" framing is a fair summary of the best available evidence, though the precise ratio varies by subgroup (Black African vs Black Caribbean) and by the specific time period and methodology used.
