From 2008 to 2012, the median age of diagnosis of prostate cancer was 66, and the incidence rate was 138 cases per 100,000 men per year.[1]Many studies suggest that CAM use is common among prostate cancer patients, and the use of vitamins, supplements, and specific foods is frequently reported by these patients. For example, the Prostate CAncer Therapy Selection (PCATS) study was a prospective study that investigated men’s decision-making processes about treatment following a diagnosis of local stage prostate cancer. As part of this study, patients completed surveys regarding CAM use, and more than half of the respondents reported using one or more CAM therapies, with mind-body modalities and biologically based treatments being the most commonly used.[2]
