Detecting breast cancer's fingerprint in a droplet of blood - The earlier breast cancer is detected, the better the chance of successful treatment and long-term survival. However, early cancer diagnosis is still challenging as testing by mammography remains cumbersome, costly, and in many cases, cancer can only be detected at an advanced stage. A team based in McGill University's Faculty of Medicine has developed a new microfluidics-based microarray that could one day radically change how and when cancer is diagnosed.
