The invention claimed is: 1. A method of assessing a change in the structural matrix, cellular, or mitochondrial components of living tissue comprising:using a radiation source to expose living tissue to monochromatic radiation at about a first wavelength;using the radiation source to expose living tissue to monochromatic radiation at about a second wavelength different from the first wavelength;using a radiation detector to detect fluorescence emitted by the exposed living tissue in response to the radiation at about the first wavelength;using the radiation detector to detect fluorescence emitted by the exposed living tissue in response to the radiation at about the second wavelength;using a processing circuit to derive an indication representative of the change in the structural matrix of the living tissue based on the fluorescence detected;using the radiation source to expose living tissue to broadband radiation;using a scattering detector to detect scattering re-emitted from the exposed living tissue in response to the broadband radiation; andusing the processing circuit to derive the indication representative of the change in the structural matrix of the living tissue based also on the scattering detected.
