How Lasers Are Used in Medicine?
One common and incorrect belief is that basic high power green lasers can be used to heal or treat small cuts and nicks. If a laser is powerful enough, it will not heal a wound it will just burn it and in the process cauterize it. Cauterizing a wound with a laser may reduce the likelihood of infection but the burn will do much more damage.
Infrared laser pointers are commonly used to treat soft tissue injuries such as bruises and strains. Using a process known as bio-stimulation, infrared lasers can penetrate below the skin and vitalize cells. This in turn improves microcirculation, immune response, inflammation and reduces pain
Laser acupuncture: Is basically a non invasive method that uses infrared lasers to stimulate acupuncture pressure points and is ideal for people who have a fear or needles or can’t tolerate the sensation of needles entering their body. Laser acupuncture is an ideal method for treating soft tissue injuries and giving pain relief for both acute and chronic illnesses. Lasers of 500mW or more are likely to cause skin burns.
Tattoo removal: Pulsed lasers are used that fire short and intense burst of light through the skin into the tattoo pigment. The pigment is broken down and then naturally removed over time by the body’s immune system. Gone are the days when tattoo removal involved scaring and the loss of skin. Now using laser tattoo removal, a tattoo can be completely removed leaving the skin healthy, intact and completely tattoo free.
Surgery: For many types of surgery, the traditional scalpel has now been replaced by lasers. The advantages of laser surgery are is it is comparatively bloodless and the heat of the laser keeps the wound germ free and reduces the risk of infection. Laser surgery is also faster and therefore cheaper.
Sperm mobility: Research indicates that low level laser therapy improves sperm motility when applied in doses. The laser frees up chemical pathways in the sperm which releases energy from the mitochondria, causing the mitochondria to work better and faster.
Acne: Roughly 30% of acne consists of fat so the removal of fat will reduce acne. The fat in acne contains specific chemical bonds that are broken down by lasers, allowing the body to absorb the fat.
Cancer: This is one area where there is a lot of controversy and the benefits of lasers are unproven. Many doctors claim that they have used lasers to make significant progress in the treatment of cancer where conventional methods failed. Currently there is not enough research to prove the benefits of lasers in cancer and at least one prominent doctor has been taken too caught for fraud, charged with false claims in the use of lasers to treat cancer.
