A year-by-year age analysis of colorectal cancer rates among adults in the United States has found a 46% increase in new diagnoses from ages 49 to 50, indicating that many latent cases of the disease are likely going undiagnosed until routine screenings begin at 50, according to a new study by...
Advanced-stage cancer diagnoses declined following health insurance expansion in Massachusetts, likely due to increased access to screening and diagnostic services that identified cancers earlier, according to new research published by Sabik et al in the journal Medical Care. The analysis...
Thibaud Kössler, MD, PhD, of Geneva University Hospital, discusses the first trial to study the efficacy and safety of anti–PD-1 immunotherapy plus short-course radiotherapy in localized microsatellite-stable rectal cancer.
