Annual versus less frequent mammographic surveillance in people with breast cancer aged 50 years and older in the UK (Mammo-50): a multicentre, randomised, phase 3, non-inferiority trial
For patients aged 50 years or older and at 3 years post diagnosis, less frequent mammograms were non-inferior compared with annual mammograms for breast cancer-specific survival, recurrence-free interval, and overall survival, and should be considered for this population.
