Laser therapy

Laser therapy are medical treatments that use focused light. Laser light is a very special kind of light. Unlike most light sources, it is tuned to very specific wavelengths.

What is Laser Therapy?

Laser therapies are medical treatments that use focused light. Laser light is a very special kind of light. Unlike most light sources, it is tuned to very specific wavelengths. This allows it to be focused into powerful beams. Laser light is so intense it can be used to shape diamonds or cut steel.

In medicine, lasers offer surgeons the ability to work very precisely. They can focus on a small area and damage less of the surrounding tissue. Patients who have laser therapy may experience less pain, swelling, and scarring than with traditional surgery. However, laser therapy is expensive. It may also require repeated treatments. Laser stands for: Light Amplification by Stimulated Emission of Radiation.

What is Laser Therapy Used For?

Laser therapy is used in many procedures. It may be used to:

  • shrink or destroy tumors, polyps, or precancerous growths
  • relieve symptoms of cancer
  • remove kidney stones
  • remove part of the prostate
  • repair a detached retina
  • improve vision (“laser eye surgery”)

Lasers can have a cauterizing (sealing) effect. They may be used to seal:

  • nerve endings, to reduce pain after surgery
  • blood vessels, to help prevent blood loss
  • lymph vessels, to reduce swelling and limit spread of tumor cells

According to the National Cancer Institute (NCI), lasers may be useful in treating the very early stages of cancers such as:

  • cervical cancer
  • penile cancer
  • vaginal cancer
  • vulvar cancer
  • non-small cell lung cancer
  • basal cell skin cancer (NCI)

When used in cancer treatment, laser therapy is usually used alongside other treatments such as surgery, chemotherapy, or radiation. Laser therapy is also used cosmetically. It can:

  • remove warts, moles, birthmarks, and sun spots
  • remove hair
  • lessen the appearance of wrinkles, blemishes or scars
  • remove tattoos

How is Laser Therapy Done?

Laser therapy techniques vary based on the specific procedure being performed. For example, if a tumor is being treated, a flexible endoscopemay be used to direct the laser. This is a thin, lighted tube used to view tissues inside the body. The endoscope is inserted through an opening in the body, such as the mouth. The surgeon then aims the laser and shrinks or destroys the tumor. In contrast, for cosmetic procedures, lasers are often applied directly to the skin.

Different lasers are used for different procedures:

  • Carbon dioxide (CO2) lasers make shallow cuts. They are often used for superficial cancers, such as skin cancer.
  • Argon lasers also make shallow cuts. They can be used to activatephotosensitizing (light activated) drugs during Photodynamic therapy (PDT). This type of cancer treatment combines light with chemotherapy to kill more cancer cells.
  • Nd:YAG lasers can travel along optical fibers. They are used in Laser-induced interstitial thermotherapy (LITT), a type of cancer treatment.

What are the Risks of Laser Therapy?

Laser therapy has some risks. According to the University of Maryland Medical Center (UMMC), the risks for skin therapy include:

  • triggering the herpes simplex virus, the virus that causes cold sores and genital herpes
  • bleeding
  • infection
  • pain
  • scarring
  • skin color changes

There are other potential downsides to laser therapy.

  • The effects may not be permanent. Repeated treatment may be necessary.
  • Some laser surgery is done when a patient is under general anesthesia, which carries its own set of risks.
  • Treatments are expensive. This type of therapy may not be affordable for many patients.

What are the Benefits of Laser Therapy?

There are many potential benefits of receiving laser therapy:

  • Lasers are more precise than traditional surgical instruments. Cuts can be made shorter and shallower. This causes less damage to tissue.
  • Operations are generally shorter than traditional surgeries. They can often be done on an outpatient basis. Patients don’t have to spend the night in the hospital. If general anesthesia is required, it is usually used for a shorter time..
  • Patients usually heal faster. They may have less pain, swelling, and scarring than with traditional surgeries.

What is the intravenous blood laser therapy

Lāzeroterāpija – is a relatively new method of treatment with low-intensity light – a laser application.

It is important to realize that at this method the body is not entered no substances with specific iedarbābu, but is easily adjusted for self-regulation and homeostasis (balance) Maintenance, who were disturbed. Methods of safety and efficacy is related to the effects on the body’s normal physiological reactions.

Depending on the length of the beam, there are several rays:

  • Ø 0.365 microns – ultraviletais beam;
  • Ø 0.405 microns – blue stars;
  • Ø 0.532 microns – green ray;
  • Ø 0.635 microns – red beam.

Ultraviolet rays PROVEN carcinogenic effects, due to the fact HIS USE OF THERAPY IN THE WORLD IS NOT RECOMMENDED. The maximum positive effect gives blue stars and red stars.

Intravenous blood laser therapy (ILT) mechanisms of action

It has shown that ILT changes take place at three levels:

  • blood cells;
  • Whole properties (plasma COMPOSITION, rheology);
  • a systematic response of various organs and tissue level.

The main effect associated with kalcij-dependent processes of blood components ILT exposure:

  • at low intensity light – a laser, the effects on blood components vacated essential calcium ions in the blood normalize mutual relations;
  • laser restores impaired Ca 2+ homeostasis through the red cell membrane on both sides;
  • Ca 2+ increasing the concentration of the light beam affects activates and increases white blood cell activity.

Therapeutic mechanisms of action:

  • Cellular and humoral immune correction;
  • Display enhanced phagocytic activity of macrophages increase;
  • Complement and blood bakteristātiskās activity increase;
  • C-reactive protein and the average molecular level reduction;
  • Immunoglobulin IgA, IgM, IgG accretion of blood serum;
  • Increase in the number of lymphocytes and their functional activity change
  • T-helper / T-suppressor correlation stabilization
  • The body’s non-specific resistance increase;
  • Rheological properties of blood and microcirculation improvement
  • Vasodilatation effect
  • Anti-inflammatory effect;
  • Analgesic effect;
  • Blood-ion composition of normalization;
  • Blood oxygen transport function increase;
  • Blood proteolytic functions of normalization;
  • Blood antioxidant functions of normalization;
  • The arterio-venous oxygen difference, increase in tissue metabolism normalization ratio;
  • Erythropoietic stimulation;
  • Exchange process (protein, lipids, carbohydrates, cellular energy BILANSS) normalization;
  • The regeneration process of normalization and stimulation.

Side effects

  • slows the progression of complications of diabetes, thyrotoxicosis patients
  • reduces the platelet “clumping” together with the clot
  • strengthens the immune response,
  • reduces inflammation,
  • reduces the rash of skin problems,
  • improving lung, kidney and liver functions,
  • removes or reduces pain,
  • It dilates blood vessels, improves blood circulation, microcirculation and tissue condition,
  • increases the supply of oxygen to tissues and cells,
  • slows down the body’s aging process.
