Improving breast cancer chemo by testing patient's tumors in a dish

A technique that monitors the response of 3D chunks of a patient's tumor has been developed to determine how effective different anti-cancer drugs will be before starting chemotherapy. In a new article, the engineers describe applying the technique to the three major forms of breast cancer. They report that the test can detect significant drops in the metabolic activity levels of all three types of tumors within 72 hours when exposed to an effective drug whereas tumors that were resistant to a drug show no change.
