This is awesome--the iKnife ("Intelligent" knife) for cutting away cancer, can also detect the cancerous cells.
I had previously heard about dogs being able to sniff cancers such as lung, ovarian, and skin--but never a surgical knife doing this.
With the iKnife, a surgeon can use a electrosurgical knife to cut/burn away cancerous tissue, but even better yet, this knife sucks away the smoke containing the vaporized tissue to a mass spectrometer that analyzes the particles and is said to be 100% accurate (so far) in detecting cancerous tissue (from those that are normal).
This is critical because it can be lifesaving in guiding surgeons not to miss any of the cancer (and therefore also helps avoid repeat surgeries) as well as not removing unnecessary tissue that is not cancerous.
Dogs can help alert us to hidden cancers within and the iKnife can help remove them with greater precision and success.
Hopefully, with G-d's help, one day we won't need either anymore. ;-)
