- fluorescence-guided surgery
- listen (floor-EH-sents-GY-ded SER-juh-ree)
- Surgery that uses a fluorescent substance and a special microscope to show tumor margins (edges) so that more of the tumor can be removed. The substance is given by mouth and is taken up by fast-growing cells. These cells light up when seen under a microscope with a special blue light. This may help doctors to remove as much tumor as possible without harming healthy tissue. Fluorescence-guided surgery is being studied in the treatment of certain types of brain tumors.
