<h3>Background</h3> The effects of low-dose CT screening on disease stage shift, mortality and overdiagnosis are unclear. Lung cancer findings rates reported at the end in Danish Cancer Screening Trial. <h3>Methods</h3> 4104 men women, healthy heavy smokers/former smokers were randomised to five annual screenings or no screening. Two experienced chest radiologists read all scans registered location, size morphology nodules. Nodules between 5 15 mm without benign characteristics rescanned...

<h3>PURPOSE</h3> Cancer screening programs have the potential of intended beneficial effects, but they also inevitably unintended harmful effects. In case mammography, most frequent harm is a false-positive result. Prior efforts to measure their psychosocial consequences been limited by short-term follow-up, use generic survey instruments, and lack relevant benchmark—women with breast cancer. <h3>METHODS</h3> this cohort study 3-year we recruited 454 women abnormal findings in mammography...
