Significant research has been conducted in the United States regarding the importance of T-cells and their role in fighting cancer. The article regarding the research was published in 2012 in an advanced scientific journal. Further academic and scientific research has subsequently been conducted in other countries, with similar findings i.e. the fundamental role of T-cells in preventing and fighting advanced forms of cancer. Mr. Gu’s exercises are for people with advanced cancer to encourage the production and direction of T-cells to function more efficiently in the role of fighting aggressive forms of cancer In 2010, these exercises were posted on YouTube https://www.youtube.com/watch?v=mSR3jwOI6sY the exercises are simple, and everyone can do them. Improving T-cell production and function not only helps advanced cancer patients, it is very effective for cancer prevention by increasing the ability of T-cells to recognize cancer cells - a necessity for maintaining a healthy human body. Cancer cells are mutated from regular cells in our body; therefore, T-cells must be able to identify cancer cells and direct leukocytes to fight the mutated cells as well as viruses (such as the flu) which are introduced from the outside. T-cells can easily identify the difference between internal mutations and externally introduced pathogens and be activated. When the body is actively involved in the fight against both outside viruses and internally mutated cells, fatigue and high fever result, which is symptomatic of the immune system's response. Exercise assists the body in this battle by improving blood circulation. For example, an increase in blood flow to the brain, neck and the cleaning of the lymphatic system result from this series of exercises which are primarily designed to increase the flow of blood. Additionally, proper exercise results in endocrine system activation. By tapping the thymus to stimulate and activate that gland, a higher quality T-cell can result; we can encourage the body to recreate the original intelligence of T-cells, so that the T-cells are better able to do their proper function, which is to eliminate cancer. Not everyone is able to stimulate and produce higher quality T-cells, but most people can do it with exercise. T-cell exercises are not harmful to the body. The exercises can give cancer patients hope for survival. Before doing T-cells exercises one should do immune system stepping enhancement exercises https://www.youtube.com/watch?v=sJ0rXBU2nNI to warm up the body. Stretch the area of the kidneys and activate adrenal glands to increase body heat. The body temperature of people with cancer is cooler than that of healthy people, especially the extremities. The purpose of stimulating the lymphatic system is to improve lymphatic functions; stomping the foot forcefully on the floor vibrates the bone marrow to produce white and red blood cells etc., and helps blood from the lower extremities flow back to the heart. This improves heart function, also providing adequate blood circulation to the thymus. The appropriate support of blood allows the thymus to produce a better quality T-cell.
