A new technology for cancer detection that eliminates the need for drawing blood has been developed by Purdue University researchers.

Researchers from Purdue's Cancer Center, Department of Chemistry and Weldon School of Biomedical Engineering collaborated with cancer and biotechnology experts from the Mayo Clinic to develop technology to detect tumor cells within the human body. By shining a laser on surface veins, such as those on the wrist and inside the cheek, researchers are able to reveal and count circulating tumor cells.
