Women with false-positive mammogram face higher risk of later breast cancer

False-positive mammography may not just be a false alarm, findings suggest.

Women who receive a false-positive mammography result are 61% more likely to develop breast cancer over the next 20 years than women without a false positive, a study shows. 

Researchers from Karolinska Institutet in Sweden said the risk was highest in the first four years following a false-positive result, as well as for women aged 60-75 and those with lower breast density.
