Experimental device helps surgeons ensure they have removed all cancerous tissue

Surgeons may have a new way to smoke out cancer.

An experimental device can help surgeons make sure they have removed all the cancerous tissue, doctors reported last week in the journal Science Translational Medicine. Surgeons typically use knives that heat tissue as they cut, creating a sharp-smelling smoke; some of the tissue is sent to a lab for assessment while the patient remains on the operating table. The new knife analyzes the smoke and can instantly signal whether the tissue is cancerous or healthy.
