    Infrared light waves, possible anti-tumor therapy

    London, Nov 8 (Prensa Latina) The application of infrared light waves that trigger an antibody administered against tumors could become an effective treatment for various cancers, scientists today released in the journal Nature Medicine. Experiments with mice implanted a type of cancer called squamous esponicelular back therapy showed that only affects the tumor cells without harming healthy tissue. The study by scientists at the Cancer Institute of Maryland, was to manage biological models an antibody that targets proteins on the surface of cancer. Then they added a chemical called IR700 on the antibody and then bombed infrared light waves activated by IR700. These wavelengths can penetrate several centimeters below the skin. As a result, mice treated with light waves lived longer compared with the control group. Although in this experiment there were no collateral damage, scientists indicated that more research is needed to determine formal toxicity. At present the conventional treatments for tumors are divided into three categories radiation, surgical removal and chemotherapy. rr / mor

    Infrared light proves to be effective in fighting cancer

    In animal tests, antibodies, after being activated by lightning, killed cancer cells without causing side effects

    Researchers at the National Cancer Institute of the United States used infrared light in testing a new treatment against cancer. The study, published in the journal Nature Medicine , has made ​​antibodies were triggered by lightning, to kill cancer cells without harming healthy and what is most striking, apparently without causing side effects.

    Currently there are three main ways to fight cancer: surgical removal, radiation therapy and chemotherapy. Although effective against several types of the disease, these treatments also cause side effects, what motivates scientists to seek new ways to eradicate the disease.

    Tests - The therapy developed by U.S. researchers inserted in the laboratory cancer cells in the back of mice and then a chemical called IR700 antibody was placed on the animals. After the animals were given specific drugs for the disease, infrared light has been thrown upon them, the IR700 to be activated, the antibodies were able to target and kill cancer cells.

    Experts observed that the tumor of rats given these rays significantly decreased in size. In addition, healthy cells around the cancer had not been affected and the animals showed no side effects.

    In previous studies, which also sought to use infrared light, the antibodies were not very specific to act against cancer cells and eventually killing other unaffected. The results, however, only moved when the IR700 has been applied in antibodies.

    Researchers do not yet know whether the results would be the same in humans, but say that further research, including in different animals, will be made before the test is done on men. If this proves to be effective in humans, experts believe that millions of people worldwide will be spared of surgical procedures and side effects in the search for a cure for cancer.
