A correspondence in The Lancet argues that the WILLOW trial's Cohort B results reveal a mismatch between the drug's biological mechanism and the composite endpoint chosen to measure it, complicating …
Researchers have mapped the genetics of cat cancer at an unprecedented scale, uncovering surprising similarities with human tumors that could improve precision treatments for both species.
A new peer-reviewed review in Environmental Health Perspectives identifies at least 485 chemicals used in US pesticide products that are linked to breast cancer, including hundreds of inactive ingredients that …
A reanalysis of all eight major randomized mammography trials suggests overdiagnosis rates are below 5%, far lower than the 30% to 50% figures that have shaped screening debates for years.
Adaptive platform trials are accelerating infectious disease research by allowing multiple treatments to be tested simultaneously and new candidates to be added as data emerges, according to a World Report …
