A new pen-like microscope has been developed by researchers from the University of Washington in order to help doctors detect cancer cells more efficiently. When doctors are in the process of cutting tumors, it is all about scans taken of the tumor and the experience of the doctor as well. This is because at any point in time during a surgery, the doctor does not exactly know where the tumor starts and where it stops.
“Surgeons don’t have a very good way of knowing when they’re done cutting out a tumor,” according to Jonathan Liu, the senior author of the research. “They’re using their sense of sight, touch, pre-operative images of the brain, and sometimes it’s pretty subjective.”
“Being able to zoom and see at the cellular level during the surgery would really help them accurately differentiate between tumor and normal tissues, and improve patient outcomes.”
