Where you live may play an important role in your risk of prostate cancer. If you live in Asia, East Asia, Central America and South America, you may have a lowered risk. Conversely, if you live in North America, Europe, and Australia, you may have an increased risk. In one study, men who moved from China raised their risk from 2% to 17%. In the United States, different states have different risks also. If you live 40 degrees or higher in latitude, the lower amount of sunlight may make you have an even higher risk of prostate cancer.
