Researchers at the Fred Hutchinson Cancer Research Center in Seattle found that African-American men had a 30-43% chance of developing prostate cancer, compared to 24-29% in the general population. Also, African-American men were 44-75% more likely to have cancer that spread beyond the prostate when they were diagnosed. This indicates that African-American men are more likely to develop fast-growing cancers. The authors suggest that African- American men have a baseline PSA test at least three—and up to nine—years earlier than men in the general population.
