The nerve-racking wait for cancer-screening results can go on for
several days, as clinicians analyze images and biopsies. A new handheld
device could significantly shorten that stressful period. Scientists at
Massachusetts General Hospital and Harvard Medical School have
engineered a portable device that plugs into a smart phone and reduces
the time it takes to detect cancer to just an hour. The device takes a
small tissue sample and quickly analyzes it for telltale cancer
proteins. When the latest prototype was tested on 50 patients with
gastric-related cancer, it detected malignancies with 96 percent
accuracy—better than existing laboratory-based tissue-sampling tests.
The results of the study were published last week in Science Translational Medicine.
