When a man is diagnosed with prostate cancer
, his brothers are twice as likely to develop the disease as well, often at an earlier age.
New research finds these brothers are aware of their increased risk and many have taken vitamins or supplements to improve their health. The research is reported in two papers from the University of Michigan Health System .
Men participating in the research study said they felt they had a 50 percent chance of developing prostate cancer within their lifetime, and more than half of the 111 men surveyed said they were at least somewhat concerned about developing the disease. Lifetime risk for men with one first-degree relative with prostate cancer is about 56 percent, suggesting that the men surveyed were accurately assessing their risk. Results of the study will be published in the April 1 issue of Cancer .
In a related study, researchers asked the same group of men about their use of complementary and alternative medicine. More than half said they were currently taking at least one vitamin or supplement and 30 percent were using a type of complementary medicine linked to prostate health or prostate cancer prevention. Results of that study were published in the February issue of Urology .
