Abstract:
Introduction: To reduce mortality, all guidelines advice women with very high breast cancer (BC) risk, due to a pathogenic variant (PV) in genes like BRA1/2 or chest wall irradiation between age 10-30 yrs., annual screening with Magnetic Resonance Imaging (MRI) and 2 or 3D mammography (Mm).1-6 For MRI, starting age for this group is usually 25 years. However for Mm some guidelines advise annual from age 30 yrs.1,2, others 10 yr. younger than the youngest family member 4,5, or for BRCA1 biennial from age 40 yrs.7 USA and Canadian but not European guidelines advice MRI screening also for women with a ≥ 20% lifetime breast cancer (BC) risk, while the European Eusobi guideline, unlike the US and Canadian, now advises to screen women with extremely dense breasts with MRI although not yearly.8 Considerations and evidence: We need to balance the possible benefit with the disadvantages of screening, like false positive rate, possible overdiagnosis and cost. We therefore have to use the optimal frequency of screening, depending on the expected tumor growth rate, which varies with a woman’s age and the cause of the increased risk.9 Two recent randomized trials one in women with familial risk the other for extremely dense breasts showed how much MRI advances BC detection compared to mammography, at which side effects.10,11 Observational and modelling studies show varying additional value of Mm to MRI-screening for different risk – and age groups.12-17 Conclusion: Screening for women at high risk can be better tailored to the age and risk-group.
