A meta-análise de seis grandes ensaios clínicos envolvendo quase 800 mil homens confirma o que muitos esperavam e outros temiam admitir: o simples exame de sangue PSA salva vidas. A organização Cochrane, reconhecida pela rigor com que sintetiza evidências médicas, concluiu que dois homens em cada mil testados escapam da morte por cancro da próstata graças ao rastreio. É uma vitória modesta em escala individual, mas significativa quando multiplicada por populações inteiras — e um lembrete de que a medicina preventiva raramente oferece certezas absolutas, apenas probabilidades que, somadas, impo

Increased demand for PSA screening tests will likely expand access to preventive healthcare, though widespread screening may increase out-of-pocket costs for consumers and insurance premiums. Potential for overdiagnosis and unnecessary treatments could increase healthcare burden on households.
Governments may expand PSA screening coverage in public health systems and insurance mandates. Regulatory bodies may establish screening guidelines and age thresholds. Healthcare systems will need to allocate resources for mass screening programs. Potential policy debate on cost-effectiveness given the 500:1 screening-to-prevention ratio.
