These recommendations are for women who do not have any symptoms of breast cancer, are not at high risk of breast cancer, and want to know when they should be screened.

Healthcare question

Should organised mammography screening vs. no mammography screening be used for early detection of breast cancer in women aged 40 to 44?


For asymptomatic women aged 40 to 44 with an average risk of breast cancer, the ECIBC's Guidelines Development Group (GDG) suggests not implementing mammography screening.

Recommendation strength ­

  Conditional recommendation against the intervention

  Moderate certainty of the evidence

Subgroup considerations

This recommendation does not apply to high-risk women (see recommendations for women with high breast density).

Considerations for implementation and policy making

GDG members agreed on the need for additional imaging techniques in this age group, as well as the need for shared decision making.

Monitoring and evaluation

Future monitoring and evaluation of screening services should consider benefits and risks in the context of evolving treatment and management protocols. Monitoring and evaluation criteria are being developed within the ECIBC initiative

Research priorities

1. Carry out evaluations of the efficacy of the intervention, time intervals, risk factors and stratification of women, as well as context specific cost-effectiveness in this age group.

2. Carry out studies addressing the role of other screening modalities (such as magnetic resonance imaging MRI) in this population.
