Answer to Question #7356 Submitted to "Ask the Experts"

The following question was answered by an expert in the appropriate field:
You should know that a laser is simply a powerful beam of visible light at one frequency (monochromatic light). A laser beam can harm your eyes (retina) or skin because it can heat the skin or retina to temperatures that are damaging. Therefore, anyone using a laser for therapeutic or other purposes should be trained on how to use it safely.
Probably the tissues in your body that are most protected from a laser are your fetus and your internal organs. Your fetus will not be at risk because you are using a laser. But for your own peace of mind, you should be instructed on how to use the instrument. For the fetus, the laser beam can not reach to the depth of the uterus from an external laser beam. So when you become pregnant your embryo will not be at risk.
If you are healthy, are young, and have no reproductive or developmental problems or family history of reproductive or developmental problems, your risk for birth defects is 3 percent and for miscarriage, 15 percent. These are background risks with which every woman begins her pregnancy. Neither you nor I can change these risks. Good luck with your future pregnancy.
