01
A medical college updated breast cancer screening guidelines for average-risk women, recommending biennial mammography for ages 50-74 and individualized decisions for 40-49, shifting from previous annual recommendations.
02
These new guidelines matter because they aim to reduce false positives, overdiagnosis, and unnecessary interventions by balancing early detection benefits with the harms and costs associated with more frequent screening.
03
Following these changes, healthcare providers will need to adapt their screening protocols and engage in more personalized discussions with patients, especially those aged 40-49, regarding their individual risk factors and screening choices.

The American College of Physicians (ACP) has issued updated guidance on breast cancer screening for asymptomatic, average-risk women, recommending mammography every two years for those aged 50 to 74.
For women aged 40 to 49, the ACP advises that screening decisions should be individualized through shared decision-making, weighing personal risk factors, values and preferences, and potential harms such as false-positive results and overdiagnosis.
The guidance also suggests routine screening is not generally .
Why the ACP favors biennial screening
According to the ACP, available evidence does not show an added benefit of annual screening compared with biennial screening for average-risk women, while annual screening can lead to more false-positive recalls and biopsies, creating additional patient burden and costs.
Dense breasts and additional imaging
For individuals with dense breasts, 3D mammography may be considered. However, the ACP does not routinely advise other supplemental imaging for average-risk individuals.
The updated recommendations reflect the ACP’s assessment of clinical evidence on screening effectiveness and the trade-offs between earlier detection and harms related to unnecessary follow-up testing and interventions.
