Schulder said he thinks it would be possible for fluorescence to be used in other types of surgeries, if surgeons could become comfortable using a surgical microscope with the benefit of a special light (something neurosurgeons are accustomed to using). He noted that he also thinks the technique might apply to some spinal surgeries, where visualizing the spinal cord is critical.

Schulder said he thinks the use of fluorescence in cancer surgery is promising. "It's a very important concept: if you can see a tumor better, you can remove it without affecting healthy tissue."
