Breast cancer screening trials for under 50s does not show significant effect

From Cancer Research UK today, a ten year trial in which women between the ages of 40 and 50 were invited for annual breast screening did not show a significant reduction in breast cancer mortality. The trial was the first of its kind to invite only women of 40 or 41 at the start of the trial to ensure all results were based solely on screening before age 50. Currently, when women reach the age of 50 they are invited for screening every three years by the NHS Breast Screening Programme. Should we change our recommendations in the US and use these funds elsewhere in the prevention field?
