How Lasers Are Used to Treat Cancer
The word LASER stands for Light Amplification by Stimulated Emission of Radiation.
Laser light is different from regular light. The light from the sun or from a light bulb has many different wavelengths and spreads out in all directions. Laser light, on the other hand, has a single, high energy wavelength and can be focused in a very narrow beam. This makes it both powerful and precise.
Treating cancer with lasers
Lasers can be used in 2 main ways to treat cancer:
- To shrink or destroy a tumor with heat
- To activate a chemical – known as a photosensitizing agent – that kills only the cancer cells. (This is called photodynamic therapy or PDT.)
Though lasers can be used alone, they are often used with other cancer treatments, such as chemotherapy or radiation therapy.
For the most types of photodynamic therapy (PDT), a special drug called a photosensitizing agent is given into the bloodstream. It takes approximately 40-60 minutes for the photosensitizing agent to be concentrated into the cancer cells and remains in the cancer cells for a longer time than in the normal cells.
Photosensitizing agents are turned on or activated by multiple wavelength laser. It is a very effective treatment when certain wave length of laser light is exposed closely to the tumor area. When cancer cells containing higher concentration of the photosensitizing agents are exposed to the light of a certain wavelength from the special multiple wavelength laser, it causes a chemical reaction that kills the cancer cells. EHC-BUFFALO has a special unit which delivers the laser beam, with local hyperthermia to have a synergistic effect that augments the effect of PDT to kill cancer cells.
FOCAL HYPERTHERMIA LASER TREATMENT
Focal hyperthermia multiple wavelength therapy is effective adjunct cancer therapy to increase circulation, anti-inflammatory and MAKES CANCER THERAPY MORE EFFECTIVE.
To learn more about PDT, see Photodynamic Therapy.
Treating cancer-related side effects with lasers
Lasers are also being looked at to treat or prevent side effects of common cancer treatments. For instance, low-level laser therapy (LLLT) might be helpful in treating the arm swelling (lymphedema) that can result from breast surgery. Lymphedema in the arm is a risk when lymph nodes in the armpit are removed during surgery. Some studies are also looking at LLLT for preventing or treating severe mouth sores caused by chemotherapy.
Benefits of the laser treatment
LLLT Lasers have many benefits. It rejuvenates mitochondria through electron transfer chain complexes. It helps post chemo fatigue. It has an anxiolytic effect. It has immunomodulatory effect as stimulates normal stem cell biogenesis. It helps to oxygenate the tissue when delivered with hyperthermia
