Comparing our study with the age related rate of Australian males in the 60–64 year age group, there is an increased relative risk of prostate cancer of 19.08 (p<0.0001, 95%CI 4.50-80.91) and 20.56 (p<0.0001, 95%CI 6.30-67.12) times the normal population for BRCA2 and BRCAX male patients with breast cancer respectively. This evidence concerns the gene BRCA2 and prostate cancer.
