If breast cancer is suspected, doctors carry out a biopsy. However, this is invasive, painful and costly. It also takes several days to get the results. In the future, diagnosis could be made via a liquid biopsy of a patient’s blood — a gentle, cost-effective method that would deliver the results within just a few hours. A team of researchers at the Fraunhofer Institute for Applied Polymer Research IAP is working alongside partners on this innovative method.
