Core Concepts
Breast cancer screening in women over 70 may lead to overdiagnosis, raising concerns about the value and potential harms of continued screening.
Abstract
The study by Yale Medical School raises questions about breast cancer screening in older women. It tracked 54,635 women over 70 who underwent mammograms in 2002. Key findings include:
- Up to 31% of breast cancer cases in women aged 70-74 who underwent mammograms were overdiagnosed.
- Overdiagnosis increased with age, reaching 54% in women 85 and older.
- No statistically significant reductions in breast cancer deaths were associated with screening.
- Concerns include unnecessary treatments and emotional burdens from overdiagnosis.
- Recommendations vary among expert panels regarding screening older women.
- New tools are needed to accurately identify cancer severity.
