<qa>  What percentage of the population used CAM?There are some data on the use of CAM in other prostate cancer populations.13-16 In a study of 1,099 men, the prostate cancer diagnosis prompted 23.5 of the sample to start using some form of CAM for health, and 67 of the group reported having used some form of CAM for prostate health before being diagnosed.17 The study included 14 herbal or dietary therapies and 16 mind-body therapies. There were demographic differences between patients who opted for CAM use and those who did not. Patients choosing CAM were more likely to be white versus not, and more likely to be college-educated versus not. The latter variable was particularly significant in this analysis. A second study of patients living in and around San Francisco reported on 543 prostate cancer patients who completed a 30-minute telephone interview regarding complementary and alternative medicines.14 Overall, 30 of the participants used at least one type of complementary or alternative medicine. CAM users were younger than non-users and likely to be college graduates. In this group, herbal remedies and mental health approaches were the most commonly utilized, followed by dietary changes. Twelve percent of the population used two or more CAM approaches.11
