Researchers at USC's Arnold School of Public Health discussed the findings Tuesday. The study was published in the June issue of the American Cancer Society's journal Cancer. The study also looks at cancer death disparities between men and women.
Lead author James Herbert (AY'-behr) says researchers can't explain the cause of the racial differences among cancer rates, but he says late diagnosis might be a cause.
The study shows the largest racial differences are for prostate, oral and female breast cancers.
