After taking account of age, the researchers found that men with prostate cancer were 4.8 times more likely than men without prostate cancer to have a brother with prostate cancer, and 3.8 times more likely to have a sister with breast cancer.
“Collecting a family history of prostate and breast cancer, particularly among siblings, could be a key component in the clinical assessment of prostate cancer risk among African-American men,” the team writes.
“A well-documented family history of all cancer among first-degree relatives may signal a need for more aggressive prostate cancer screening practices and the adoption of screening at an earlier age,” they add.
