Risk factors for prostate cancer aren't what we think, SWOG study shows

(SWOG) When it comes to prostate cancer biopsies, risk and reality don't always match up, according to research published today in the Journal of Clinical Oncology. Investigators from SWOG, the cancer clinical trials network funded by the National Cancer Institute (NCI), found widespread detection bias after a fresh examination of data from the two largest US prostate cancer prevention trials. The research is the first systematic review of bias in prostate cancer biopsy patterns.
