The National University of Singapore has developed a new non-invasive method to detect cancer earlier, the doctors have adopted a new screening technique of shining near-infrared rays on patients’ problem areas, instead of currently using white light endoscopies.
Using the near-infrared fluorescence imaging, doctors may soon spot cancer risks before any physical signs, causing cancer cells to emit fluorescence.
Infrared red light is a biologically transparent light so it is safe for human cells and tissues.
A clinical trial using the new technique is currently being conducted at the National University Hospital.
