Further defining cancer surgery, with the device healthy cells around the area can be left untouched. This has to also improve the healing time. Imaging and the tool to destroy the cancer cells are done with the same device. It has not been used on either humans or animals yet and the probe needs to be reduced to the size of a standard endoscopic device to work with existing technology. 
More work in progress but it sure appears to be a potential forthcoming breakthrough at some point in time. BD
“Engineers at the University of Texas at Austin have patented a laser microscalpel that allows a surgeon to operate on tissue one cell at a time, precisely targeting disease while leaving healthy surrounding cells alive. The device combines two technologies--a femtosecond laser and two-photon fluorescence microscopy--into a single miniaturized, flexible probe. The probe can target single cells in three-dimensional space, penetrating up to 250 micrometers into tissue.”
