Infrared spectroscopy aids cancer diagnosis

A genetic algorithm developed by UK scientists could aid the use of infrared (IR) spectroscopy in cancer diagnosis. 

IR spectroscopy is a non-destructive method for the analysis of cells, tissues and fluids that has been used to detect different diseases and stages of malignancy in infected prostate, cervical and colon tissues. But methods to process the cells before analysis are not standard throughout different laboratories, which can make the results difficult to interpret by non-specialists in hospitals.  More...
