An analysis of 35,000 stage II–III colon cancer cases shows relapse risk peaks in year one and falls below 0.5% per six-month interval by year six, offering a practical definition of cure and a basis to taper long-term follow-up. A second study estimates U.S. inhaler use generates over two million metric tons of annual emissions, with propellant-free devices offering lower-impact alternatives. Finally, lifestyle cohorts reveal about one-quarter of people with prediabetes can normalize glucose without weight loss, conferring >70% risk reduction over a decade and spotlighting fat distribution as a modifiable target.
