Mightier Than the Scalpel: Pen-Sized
Microscope Spots Cancer
University of Washington mechanical engineers have de-
veloped a handheld microscope that helps medical profes-
sionals distinguish between healthy and cancerous cells in an
offi ce setting or operating room.
When surgeons remove a malignant brain tumor, they don't want to leave
cancerous material behind, but once they open up a patient's skull, they
don't have time to send tissue samples to a pathology lab.
This miniature microscope would allow surgeons to see at a cellular level
in the operating room and determine where to stop cutting.
