It also found that black men were four times as likely to get the most severe forms of cancer than the rest of the population.
Black men are twice as likely as whites to die before reaching retirement age.
Nearly half of black men have been diagnosed with prostate cancer, compared to 23 per cent of white men, according the study.
The researchers also found nearly half of the black men who have prostate cancer had at least one other type of cancer, which can be deadly.
