Surgical Tool Sniffs Out Cancer


This machine uses mass spectrometry to make molecular maps of tissue during surgery.

In the hope of helping oncologists remove every piece of tumor tissue during surgery, researchers are developing new imaging tools that work in real time in the operating room. European researchers have now demonstrated that a chemical analysis instrument called a mass spectrometer can be coupled with an electroscalpel to create a molecular profile of tissue during surgery. The researchers have shown that the method can be used to map out different tissue types and distinguish cancerous tissue. The device will begin clinical trials next month.
