Iranian experts are currently conducting research on the use of laser in treating some cancers, said the head of Laser Application in Medical Sciences Research Center.
"The laboratory stage of the research has been carried out successfully. Presently, we are in the process of conducting studies on animals," Mohammadreza Razaqi told Iran Daily.
He noted that some other developed nations are also performing research on the use of laser in treating breast and prostate cancers.
The specialist said no country has used laser for treating cancers among humans.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
The term 'laser' originated as an acronym for 'light amplification by stimulated emission of radiation'.
Razaqi said laser is currently used in all medical fields. He noted that laser is mostly employed in treating skin and eye diseases.
The specialist added that laser is also widely used in treating lesions in the genital region, urinary tract obstruction, prostate surgeries and breaking kidney stones.
He further said latest research shows that laser can help treat burns and diabetic ulcers as well as fatty liver.
In medicine, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue. If you have laser therapy, you may experience less pain, swelling and scarring than with traditional surgery. However, laser therapy can be expensive and require repeated treatments.
Laser operations are usually shorter than traditional surgeries. They can often be done on an outpatient basis. You also don't have to spend the night in the hospital. If general anesthesia is required, it is usually used for a shorter time.
Razaqi said laser has been used in the medical field for the last 30 years but in Iran, the process has been in use for 25 years
