- Overscreening for colorectal, cervical, and breast cancer among older adults is high, particularly for women living in metropolitan areas.
Why this matters
- Screening patients who are older than the recommended US Preventive Services Task Force (USPSTF) cutoff age and/or with limited life expectancy may cause more harm than good.
- Overscreening was assessed in cohorts of 20,937 men and 34,244 women for colorectal cancer, 82,811 women for cervical cancer, and 38,356 women for breast cancer.
- Funding: National Cancer Institute; the American Cancer Society.
- Rates of patients being screened outside the USPSTF cutoff age:
- 59.3% of men and 56.2% of women screened for colorectal cancer.
- 45.8% of women screened for cervical cancer.
- 74.1% of women screened for breast cancer.
- Participants aged ≥80 vs
- Overscreening was more common (aORs; 95% CIs) in metropolitan vs nonmetropolitan areas for:
- Colorectal cancer among women: 1.23 (1.08-1.39).
- Cervical cancer: 1.20 (1.11-1.29).
- Breast cancer: 1.36 (1.17-1.57).
- Overscreening for cervical and breast cancers was associated with having a usual source of care, good/very good/excellent self-reported health, education beyond high school, and being married or living as married.
- Observational; recall bias.
