  1. Most Women Wrong About Risk of Breast Cancer. Fewer than 10% of women accurately estimated their risk of breast cancer, as they were equally likely to overestimate or underestimate the risk.
  2. Benefits, Risks of Lung Cancer Screen Examined. Two new studies demonstrate both the promise of CT-based lung cancer screening and the obstacles to reducing the harms it may cause.
  3. Meds, Talk Both Foil Depression Relapse. In depressed patients treated successfully with cognitive therapy, antidepressants and continued talk therapy were equally effective for preventing relapse in a randomized trial.
  4. Smoking Bans Fail Unless Enforced. Implementation of an unenforced smoking ban sharply cut indoor secondhand smoke concentrations, but levels then increased steadily over the following year.
