How Safe Are Lasers For Use in Medicine?

As laser technology becomes a more common medical procedure, the question that passes many patients' minds is: How safe are lasers for use in medicine?

The easy answer is that they are extremely safe, but let me explain why. Most lasers used in medicine are low level lasers, not the metal melting science fiction laser stereotypes we've all grown up with. Low level lasers are a lot less exciting than Star Wars would lead you to believe, but they are also less dangerous and completely safe.

Lasers are basically light, very intense light, but light all the same. Lasers are becoming widely used for their monochromatic, collimated, and coherent properties. Low level lasers are used at such a low level that no cutting is actually done. The intense radiation does the work, melting away fat, scars, acne and other blemishes for which they are becoming increasingly used.

Safe and Free of Side Effects

The use of lasers is an extremely safe and non-invasive procedure that's free of side effects. Lasers work quickly to treat a variety of conditions, from non-surgical fat removal to pimple removal to chronic back and neck pain. Cold lasers used for medical procedures have a 500 mW or less, not producing enough thermal output to damage the skin being treated. These lasers are different than the heat lasers used for cutting in surgeries. The worse you'll feel is a brief tingle or a slight tickle, as if someone gently ran their fingers over the affected skin.

Safe for Metal Implants, Pacemakers and IUDs

As low level lasers are used instead of heat lasers, laser therapy is completely safe for those who have metal implants, pacemakers or IUDs. Because the lasers use light, not heat, the metal's temperature won't be affected. You should always tell a qualified practitioner if you have these additions, just to make sure.

Cancer Free With No Harm to Organs

Essentially, lasers don't cause or exacerbate cancer. They pose no harm to the body's vital organs. However, it is important that laser therapy always be implemented by a qualified practitioner, although some repeat procedures are simple enough that you can do them at home once you've been correctly shown how.
