When Can You Stop Mammograms? The Age 75 Question
SaveNo single age forces everyone to stop mammograms, but most guidelines extend routine screening to about age 74. After 75, evidence thins and the decision turns on overall health and life expectancy rather than age. Women with under a decade of life expectancy often gain little from continued screening.

Find care →Is there an age when mammograms should stop?
No official age forces every woman to stop screening, but guidelines cluster around age 74 as the point with the clearest evidence. The American College of Obstetricians and Gynecologists and other groups keep offering mammograms into the mid-70s for women in good health 2Ref 2American College of Obstetricians and Gynecologists (2017).Practice Bulletin Number 179: Breast Cancer Risk Assessment and Screening in Average-Risk Women.ACOG average-risk breast screening guidance; supports continued mammography into the mid-70s for healthy women and individualized decisions based on risk assessment and health status.. The National Cancer Institute notes that screening trials enrolled few women over 74, so the benefit beyond that age is uncertain rather than proven absent 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. Many breast cancers are still diagnosed in women in their 70s and 80s, which is one reason stopping is not automatic 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. Health, values, and life expectancy weigh more than the number itself.
Why does life expectancy matter more than age?
Life expectancy shapes the decision because the survival benefit of screening is not immediate. Finding a cancer early helps only if a woman lives long enough for that early detection to change her outcome, and that payoff can take up to about 10 years to appear 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. A healthy 78-year-old with a long life expectancy may benefit from continued mammograms, while someone the same age with advanced heart or kidney disease may not 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. This is why guidelines ask clinicians to weigh overall health, not just count birthdays 2Ref 2American College of Obstetricians and Gynecologists (2017).Practice Bulletin Number 179: Breast Cancer Risk Assessment and Screening in Average-Risk Women.ACOG average-risk breast screening guidance; supports continued mammography into the mid-70s for healthy women and individualized decisions based on risk assessment and health status.. Estimating life expectancy is imperfect, but it separates women likely to benefit from those more likely to face the harms of false positives and overdiagnosis.
What are the harms of screening later in life?
Screening harms grow more consequential with age, even as the benefit shrinks. Older women have more false positives and more biopsies for findings that would never have caused harm, a problem called overdiagnosis 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. Because some breast cancers grow slowly, a tumor found at 80 might never have become life-threatening, yet its discovery can lead to surgery, radiation, or anxiety 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. The National Cancer Institute stresses that these harms are real and must be set against a benefit that narrows after 75 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. For women with limited life expectancy, treating a screen-detected cancer may reduce quality of life without extending it, so it helps to know how often to keep screening still makes sense for you.
Does your health history change the answer?
Personal health history can push the decision in either direction. A woman with a BRCA gene change, prior chest radiation, or earlier breast cancer may have reason to continue screening later than average-risk peers 2Ref 2American College of Obstetricians and Gynecologists (2017).Practice Bulletin Number 179: Breast Cancer Risk Assessment and Screening in Average-Risk Women.ACOG average-risk breast screening guidance; supports continued mammography into the mid-70s for healthy women and individualized decisions based on risk assessment and health status.. On the other end, several serious chronic illnesses can shorten life expectancy enough that screening offers little 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. The well-woman visit is a natural place to revisit this, where a clinician reviews your conditions, medications, and priorities 3Ref 3American College of Obstetricians and Gynecologists (2018).ACOG Committee Opinion No. 755: Well-Woman Visit.ACOG well-woman visit guidance; supports the periodic visit as the setting to review age-appropriate screening, health conditions, and shared decisions about continuing or stopping preventive tests.. A brief life-expectancy estimate, which clinicians make routinely, often clarifies the choice more than age alone does. Perimenopausal and postmenopausal women sometimes assume screening ends at a set age, but the honest answer is that it stays individualized across the later decades. Keeping up with other recommended screenings still matters even if mammograms wind down.
When the decision to stop mammograms needs a clinician
Deciding when to stop mammograms is rarely obvious, and it is one of the clearest examples of shared decision-making in preventive care. A primary care clinician or gynecologist can estimate your life expectancy, review your risk and values, and help you decide whether another round of screening fits your goals 2Ref 2American College of Obstetricians and Gynecologists (2017).Practice Bulletin Number 179: Breast Cancer Risk Assessment and Screening in Average-Risk Women.ACOG average-risk breast screening guidance; supports continued mammography into the mid-70s for healthy women and individualized decisions based on risk assessment and health status.. Reasons to seek review include a new breast lump or skin change at any age, or uncertainty about whether to continue after 75 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute patient screening summary; supports that routine mammography evidence is strongest to about age 74, that benefits take years to accrue, and that false positives and overdiagnosis are recognized harms of screening older women.. Bringing a list of your health conditions and past mammogram results makes that conversation more productive.

Find care →Breast changes that warrant a clinician visit at any age
- —A new breast lump, thickening, or armpit swelling at any age is a reason to seek clinician review, regardless of your screening schedule.
- —Skin dimpling, puckering, or a newly inverted nipple is a reason to arrange a clinician visit.
- —Spontaneous bloody or clear discharge from one nipple is a reason to be evaluated by a clinician.
- —Persistent breast redness, swelling, or warmth is a reason to seek prompt clinician review.
This article is general health education, not medical advice. Whether and when to stop mammograms depends on your overall health, life expectancy, and personal risk, and should be decided with a primary care clinician or gynecologist.
