The editors of Science magazine picked cancer immunotherapy as 2013’s major medical breakthrough achievement. Cancer immunotherapy is the use of the immune system to fight cancer. This is done by stimulating the patient's immune system to attack cancer cells. According to an article on NewsObserver.com, “Scientists have thought for decades that harnessing the immune system to battle tumors should be possible, but it has been incredibly difficult to make it work.” The article was published on January 5, 2014 (2).
“So far, this strategy of harnessing the immune system to attack tumours works only for some cancers and a few patients, so it's important not to overstate the immediate benefits. But many cancer specialists are convinced that they are seeing the birth of an important new paradigm for cancer treatment,” said Tim Appenzeller, chief news editor of Science magazine (1).
Cancer researchers say that they “have turned a corner because two different techniques are helping a subset of patients. One involves antibodies that release a brake on (or stimulate) T cells (a type of white blood cell), giving them the power to tackle tumors. Another involves genetically modifying an individual's T cells outside the body so that they are better able to target cancer, and then re-infusing them so they can do just that. (2).”
Normal cells are programmed to divide and replicate at a certain rate. Cancer cells replicate unchecked, which causes the growth of a tumor. Now, think of the immune system’s T-Cells as guards. They seek out and destroy malfunctioning cells, including cancer cells. In essence, cancer immunotherapy is either adding T-Cells (adding more guards) or teaching them to be more aggressive.
According to the Theory of Microcompetition with Foreign DNA, as detailed by Dr. Hanan Polansky on the CBCD website (3), latent viruses are the cause of most
