A doctor at Imperial College London has developed a surgical knife that analyzes the smoke produced when tissue is cauterized during tumor-removal surgery to detect whether that tissue is cancerous. The device compares smoke from the surgical site to a library of smoke signatures to determine if cancer is present in the tissue. The device was tested over a two-year period on tumors from 91 patients and was able to detect the cancer in 100% of the cases. More studies will be conducted before the device is submitted for regulatory review.
