body: Metastasis of cancer through the Lymphatic system, venous system, direct extension from one organ to another: These are three causing cancer agents. Chemicals capable of producing mutations are both naturally occurring and synthetic, and are found in the environment, food, and water supply, or have been used as drugs (in fact, cancer chemotherapeutic agents are mutagens that exploit the ability to change rapidly replicating DNA preferentially in a tumor, leading to its demise). Radiation often known as "ionizing radiation" induces adja

When a cell's DNA is badly damaged, a gene known as p53 begins to direct an emergency response by turning on several hundred genes. If repairs cannot be made, the cell may self-destruct. Now, researchers have found one of the first proteins produced in this chain of command. p53 is actually a tumor suppressor, and that it is altered in the majority of colon cancers. Since then, mutant forms of p53 have cropped up in so many tumors and aroused so much interest that Science hailed the p53 protein as the "Molecule of the Year" in 1993. The p53 gene was originally discovered in 1979 by Arnold Levine.
