Most experts recommend regular mammograms starting at age 40, but the exact schedule depends on your age and breast cancer risk. The best plan is one you decide on together with your healthcare provider.
General screening schedule
For people at average risk , many major organizations suggest starting routine screening at age 40. Common options are a mammogram every 1–2 years from age 40 through at least age 74 , with some groups favoring yearly exams in the 40s and early 50s and then every other year after 55.
Differences between major guidelines
Several professional groups agree on early and regular screening but differ slightly in timing and frequency. For example, the U.S. Preventive Services Task Force recommends mammograms every 2 years from 40 to 74 , while the American Cancer Society and others support annual mammograms from about 45–54 and then every 1–2 years after 55.
Higher‑than‑average risk
If you have a strong family history of breast cancer, known gene mutations like BRCA1/BRCA2, or prior chest radiation, you may need to start earlier and screen more often. In these higher‑risk situations, experts often advise annual mammograms starting around age 30 , sometimes with added MRI beginning in the mid‑20s to 30s, tailored to your specific risk factors.
When to stop screening
There is no single age when everyone should stop having mammograms. Many groups advise continuing as long as you are in generally good health and expected to live at least 10 more years, with decisions after about age 75 based on your health, preferences, and discussion with your clinician.
How to decide what’s right for you
To choose a schedule, discuss with your doctor:
- Your age, personal and family history, and any genetic risk.
- How you feel about the benefits of early detection versus downsides such as false positives and extra testing.
If you share your age and whether you have any known risk factors, a more tailored interval can be outlined, but final decisions should always be made with your own healthcare professional.
