Scientists say they have a made a potentially “gamechanging” breakthrough in breast cancer research after discovering how to preserve breast tissue outside the body for at least a week.

The study, which was funded by the Prevent Breast Cancer charity, found tissue could be preserved in a special gel solution, which will help scientists identify the most effective drug treatments for patients.
