Controversial Cancer Screening Study Faces Criticism from Breast Imaging Experts

Breast imaging experts have criticized a recent study published in JAMA Internal Medicine, calling it "invalid" and "specious." The study evaluated the impact of various cancer screening tests on life-days gained and reported that mammography led to zero days gained, while CT lung cancer screening led to 107 days gained on average. Experts pointed out flaws in the study's design, including the failure to assess the impact of screening participation and the use of all-cause mortality as an inappropriate study approach. They emphasized the importance of developing better ways to detect breast cancer and reducing breast cancer-related deaths through screening programs.
