Severe, long-standing GERD can damage the esophagus and cause a condition known as Barrett's esophagus wherein the normal lining of the esophagus is replaced by a lining more like that of the stomach or intestine.

Laser beam is very safe because laser medicine generally utilizes wavelengths above 632 nm (nanometer). Therefore the laser beam is not ionizing radiation (which can cause cancer) like X-rays, Gamma rays etc. Sunlight contains cancer causing wavelengths (below 320 nm), which is ultraviolet. There is no certain limit for penetration of laser light. It spreads in all directions and is absorbed in tissues. Light's intensity weakens the deeper from the target point it goes.
