Don't use advanced imaging (PET, CT, or radionuclide bone scans) to stage early breast or prostate cancer at low risk for metastasis. Setting: newly diagnosed early-stage, low-risk breast or prostate cancer without signs or symptoms of metastasis Why: Advanced imaging to stage low-risk early cancers has a very low yield of true metastases and generates false positives, cost, and radiation. Consider instead: reserve advanced staging imaging for higher-stage or symptomatic disease Source: American Society of Clinical Oncology (Choosing Wisely, US, 2012).
