New Analysis Challenges Decades-Old Breast Cancer Overdiagnosis Estimates

A new study is challenging long-standing concerns about the risks of breast cancer screening. Researchers conducted a systematic reanalysis of all eight major randomized mammography trials, carefully accounting for variables that earlier analyses may have overlooked—specifically differences in follow-up time, screening frequency, and whether participants continued screening after trials

Indoor Air Study Reveals Scented Cleaners Can Generate Lung-Penetrating Nanoparticles

A new study is raising questions about the hidden costs of that fresh, clean scent in your home. Researchers have discovered that scented cleaning products can react with ozone already present indoors to generate massive quantities of invisible nanoparticles that can penetrate deep into the lungs. The pollution forms rapidly,
