Last week the U.S. Preventive Services Task Force, a panel of independent experts, found that healthy men need no longer undergo PSA screens for prostate cancer because the tests don't save lives and lead to harm from unnecessary care. Curtis Miyamoto, chair of radiation oncology at Temple University Hospital, discussed the issues in a Q&A in the Inquirer. "I admit there are excessive screenings for men who will never actually benefit from it, but you cannot make the broad statement that we're not going to do this anymore," he said. "And just because the studies are conflicting doesn't mean we should not do it."
