6. CONCLUSIONS prior and after exposure to light of appropriate wavelength. 
Further investigations on living tumor cells from patients to 
3D-image analysis by use of a confocal laser scanning be treated are necessary in order to systematically improve 
microscope and dedicated computer hard- and software, as this kind of cancer treatment. 
described in this paper, proves to be very useful for the fast 
localization of photo-sensitizers within living tumor cells
