Black men are twice as likely to get prostate cancer as white men, and they get it younger.
Scientific Claim
Ethnicity is a significant biological determinant of prostate cancer risk, with men of African descent exhibiting approximately double the incidence and earlier age of onset compared to men of European descent.
Original Statement
“Black men have approximately double the risk of prostate cancer compared to white men and they tend to develop it at a younger age. This is not a marginal statistical difference. It's a substantial one and it means black men should be having conversations about PSA testing earlier from around 40 to 45.”

Global Patterns of Prostate Cancer Incidence, Aggressiveness, and Mortality in Men of African Descent
This study found that men of African descent are much more likely to get prostate cancer and die from it than men of European descent, which matches the claim that ethnicity plays a big role in cancer risk.
Genetic Hitchhiking and Population Bottlenecks Contribute to Prostate Cancer Disparities in Men of African Descent.
This study found that men of African descent have certain inherited genetic differences that make them more likely to get prostate cancer earlier and more often than men of European descent, which explains why the disease is more common in these populations.
Contradicting (1)
The study looked at a specific gene in Black men to see if it explains why they get prostate cancer more often, but found that gene doesn’t actually increase their risk — so it challenges the idea that this biological difference explains the higher rates.
