Breast cancer screening for women: mammograms every two years starting at age 40
For women aged 40 to 74, having a mammogram every two years is a clear recommendation in official US screening guidelines. For women over 75, and for those with dense breast tissue who need extra ultrasound or MRI scans, there is currently insufficient evidence to support such screening. If a health check package includes these extra tests at an extra charge, they are not necessary.

A mammogram costs around 200–300 yuan each time. Many regions also offer free screening programs. Each screening takes about half a day.
The United States Preventive Services Task Force is the official US agency that provides screening recommendations. Its current recommendation is: "The USPSTF recommends biennial screening mammography for women aged 40 to 74 years." Mammography is a breast X-ray. The recommendation grade for this item is B. For women aged 75 and older, as well as for follow-up ultrasound or MRI for dense breasts, it has determined there is "insufficient evidence." China's 2021 breast cancer screening guidelines recommend that women at average risk begin screening at age 45, once every 1 to 2 years. Women at high risk should begin at age 40, once a year.

Open source linkThe age to begin screening varies by country; China's 2021 guidelines recommend starting at age 45 for those at average risk. Those with parents, children, or siblings who have had breast cancer, as well as those with BRCA mutations, are considered high risk and must consult a doctor separately to determine a plan; this item does not apply.
