Washington: Physicians can now spot pancreatic cancer, one of the deadliest ever, by simply shining a tiny light within the small intestine, close to its junction with the pancreas, 100 percent of the time.Pancreatic cancer, which killed a visionary entrepreneur such as Steve Jobs of Apple, is notoriously hard to detect owing to its very deep location in the abdomen, surrounded by the gut. Mayo Clinic researchers will now test this minimally invasive technique, called Polarization Gating Spectroscopy, in a much larger international clinical trial.The light, attached to a probe, measures changes in cells and blood vessels in the small intestine produced by a growing cancer in the adjoining pancreas. The investigators theorized that there may be changes in the nearby "normal appearing" tissue of the small intestine which is much more accessible.
