Lorelei Mucci and Alicia Morgans discuss the findings of a large epidemiologic study examining physical activity and its influence on a wide range of biological processes including anti-inflammatory and insulin pathways, may be linked to a lower risk of prostate cancer. In addition to being one of the largest of its kind, the study stands out in that researchers were able to examine medical records, pathology reports, and disease-specific questionnaires, and to leverage molecular subtyping data—information that lets researchers classify types of cancer based on molecular and clinical characteristics—to better understand how prostate cancer develops.
