A study proved that mammography screenings reduces risk of dying from breast cancer by 40 percent. Experts from 16 countries assessed the positive and negative impact of different breast cancer screening methods based on a comprehensive analysis of evidence from 11 randomised controlled trials and 40 high-quality observational studies.

"This important analysis will hopefully reassure women around the world that breast screening with mammography saves lives," said professor Stephen Duffy of Queen Mary University of London. "The evidence proves breast screening is a vital tool in increasing early diagnosis of breast cancer and therefore reducing the number of deaths," he added.

"Despite evidence that mammography screening is effective, we still need to carry out further research on alternative screening methods, such as the promising 'digital breast tomosynthesis'; a newly developed form of 3D imaging which could potentially improve the accuracy of mammography in coping with more dense breast tissue," Duffy added.

The study was published in the New England Journal of Medicine. Reducing hazardous noise levels can save your heart.
