"The report has some mixed news about prostate cancer, the second leading cause of cancer death in men.
The prostate cancer death rate fell by half over two decades, but experts have been wondering whether the trend changed after a 2011 decision by the U.S. Preventive Services Task Force to stop recommending routine testing of men using the PSA blood test. That decision was prompted by concerns the test was leading to overdiagnosis and overtreatment.
The prostate cancer death rate flattened from 2013 to 2016. So while the PSA testing may have surfaced cases that didn’t actually need treatment, it may also have prevented some cancer deaths, the report suggests."
