In the body, the immunity system usually consumes particles in minutes but unfortunately, cancer and virus cells have a long worm shape so that they can avoid the immunity system for a long time and are able to spread. However, long molecules of chemicals such as iron-oxide are able to take advantage of this fact and have up to 24 hours to search and destroy cancer cells. Therefore, molecules that have a longer worm shape would be more effective against cancer since it would actually have a chance of reaching it. Many vitamins that are good anti‐cancer vitamins would include vitamins A, C, E, beta-carotene, lycopene, other phytochemicals (chemicals that are products of plants), Omega 3 fatty acids, fiber, and anti‐oxidants.Since cancer is caused by mutation of the cells, it would be best to have a diet that consists of these vitamins so that if a mutation were to occur the problem would be taken care of at the early stages.Anti‐oxidants are also good to have, because anti‐oxidants are simply minerals, and enzymes that prevent free radicals from causing damage. Free radicals are simply substances that are floating around and have an extra electron that will be added to something or will be used to take an electron away causing damage to the cells.These free radicals oxidize the cells in the body if there are not enough anti‐oxidants to neutralize is the same process by which fruits sucturning brown and metal turn to rust.
