Laser therapy can be used on patients who suffer from a variety of acute and chronic conditions in order to help eliminate pain and swelling, reduce spasms, and increase functionality.
The laser is a handheld device, about the size of a flashlight, that is placed directly over the injured area for 30 seconds to several minutes. The length of time depends on the size of the area being treated and the dose provided by the laser unit.
Lasers are more precise than surgical instruments, so cuts can be made shorter and shallower, causing less damage to the tissue. Because of this, the patient usually heals faster and may have less pain, swelling, and scarring than with a traditional surgery. The operation, itself, is generally shorter and can often be done on an outpatient basis.
Laser therapy can be used for many medical purposes. Because the laser beam is so small and precise, it allows doctors to safely treat tissue without injuring the surrounding area.
* When used in cancer treatment, laser therapy is usually used alongside other treatments such as surgery, chemotherapy, or radiation.
Laser therapy can also have a cauterizing effect. Lasers can be used to seal blood vessels, to help prevent blood loss; nerve endings, to help prevent pain after surgery; and lymph vessels, to reduce swelling and limit the spread of tumor cells.
In addition, laser therapy can also be cosmetic. It can remove hair, warts, moles, birthmarks, sun spots, and tattoos. As well as lessen the appearance of wrinkles, blemishes, and scars.
