Hazard Ratio First Degree Relatives with Prostate Cancer

father and sonA diagnosis of prostate cancer affects the family in many ways. If you have prostate cancer and have close male relatives such as sons or brothers, their likelihood of being diagnosed with prostate cancer increases.

The information below provides information about the increased risks.

  • Sons of fathers who have been diagnosed with prostate cancer have a hazard ratio of 2.12. This simply means that a son whose father was diagnosed with prostate cancer has over two hundred percent greater likelihood of being diagnosed with prostate cancer than other males in the general population.
  • If a man with brother(s) is diagnosed with prostate cancer, the hazard ratio to his brother(s) becomes 2.96, a nearly 300% higher likelihood of being diagnosed with prostate cancer.
  • If a man has a father and brother who have both been diagnosed with prostate cancer, his hazard ratio is 5.51, a 550% greater likelihood of being diagnosed with prostate cancer.

Prostate cancer is being diagnosed over 250,000 times each year in the United States. It is a disease that claims over 30,000 lives a year. Having a family history of prostate cancer strongly suggests the importance of getting tested.
