Dr. Matthias Rath defined a new direction in cancer research by shifting its primary focus from eliminating cancer cells to addressing a common pathomechanism of all cancers, which is the degradation of the surrounding connective tissue. This mechanism is a precondition for cancer metastasis (the main cause of death from cancer), tumor growth, angiogenesis and other aspects of malignancy. He suggested that the amino acid lysine and vitamin C could effectively control this process as the necessary components for optimum strength and stability of collagen and connective tissue in the body. You can learn more about this groundbreaking discovery on the website of the Dr. Rath Research Institute.
