Vitamin C Shields Cells\n\nSure they're tasty, but there's another reason that you might want to down a glass of freshly squeezed orange juice, slice a red pepper over your green salad and nibble a handful of fragrant strawberries. You'll be getting lots of vitamin C, potentially potent protection against cancer.\n\n"Approximately 90 population studies have examined the role of vitamin C-rich foods in cancer prevention, and the vast majority have found statistically significant protective effects," reports researcher Gladys Block, Ph.D., of the University of California, Berkeley. "Evidence is strong for cancers of the esophagus, oral cavity, stomach and pancreas. There is also substantial evidence of a protective effect against cancers of the cervix, rectum and breast."\n\nOne review that looked at the results of several population studies found that women with the lowest risk of breast cancer were getting about 300 milligrams of vitamin C a day, the equivalent of about 4½ oranges or about three cups of orange juice. Their risk was reduced by about 30 percent.\n\nIn a study from Latin America, an area with one of the highest rates of cervical cancer in the world, women who got more than 314 milligrams of vitamin C a day had 31 percent less risk of developing cervical cancer than women whose intakes were under 153 milligrams a day.\n\nAnd in a study from New Orleans, people getting at least 140 milligrams of vitamin C in their diets (about two oranges' worth) every day were only half as likely to develop lung cancer as those getting less than 90 milligrams a day.\n\n"Vitamin C is a potent antioxidant," explains Balz Frei, Ph.D., associate professor of medicine and biochemistry at Boston University School of Medicine.

There are many different kinds of cancer.  The accumulated effects of repeated sunburn/sunexposure can cause skin cancers.  Heavy drinking & alcoholism can cause pancreatic and liver cancers.  Smoking/second-hand smoke can cause lung cancer.  Over-exposure to radiation can cause cancer.  Existing cancers can cause other cancers.  It would take far too long to list all the causes and possible causes.  Some days I feel that everything causes cancer.\n\nAs far as prevention, there's no guarantee that anything you do will prevent it.  But you can reduce the chances.  Eat healthy, reduce or avoid red meat, moderate or no alcohol, don't smoke or linger around second-hand smoke, stay active and exercise.  Stay out of the sun as much as possible and wear sunscreen/block.  Any search on cancer prevention will give a long list of things you should and should not do.  But in the end, if you're genetically programmed to get it....\n\nDon't spend the rest of your life worrying about it.  Use common sense, live a healthy lifestyle and enjoy the life you have.

Hmm you could start by looking to see if there is a relationship between vitamin use and cancer. Or even the tried and true cancer and smoking. IT really depends on what kind of data you have access to or if you are going to collect your own.

To combat free radicals\n-----------------\nIn biological systems, the normal processes of oxidation (plus a minor contribution from ionizing radiation) produce highly reactive free radicals. These can readily react with and damage other molecules. In some cases the body uses free radicals to destroy foreign or unwanted objects, such as in an infection. However, in the wrong place, the body's own cells may become damaged. Should the damage occur to DNA, the result could be cancer. Antioxidants decrease the damage done to cells by reducing oxidants before they can damage the cell.\n\nVirtually all studies of mammals have concluded that a restricted calorie diet extends the lifespan of mammals by as much as 100%. This remarkable finding suggests that food is actually more damaging than smoking. As food produces free radicals (oxidants) when metabolized, antioxidant-rich diets are thought to stave off the effects of aging significantly better than diets lacking in antioxidants. The reduced levels of free radicals, resulting from a reduction in their production by metabolism, is thought to be a major cause of the success of caloric restriction in increasing life span.\n\nFree radical damage in the mitochondria of living cells is a byproduct of oxidative phosphorylation. Superoxide radicals are generated, which can damage mitochodrial and mitochondrial membranes. Unlike DNA in the cell nucleus, mitochondrial DNA has only a few DNA-repair enzymes and the DNA is not protected by histones.\n\nMany antioxidants, however (including vitamin C and vitamin E) can't get into mitochondria for various reasons (e.g. because they are too hydrophilic to cross mitochondrial membranes or too hydrophobic to cross the cytoplasm). Melatonin is an important natural antioxidant that has been demonstrated [citation needed] to strongly protect mitochondria from damage. A group of scientists in Russia (led by V. Skulachev) have created a custom antioxidant (a Skulachev ion forms the point of the molecule and penetrates the mitochondrial membrane; the antioxidising part is attached behind it) that can enter the mitochondria and stays there due to the membrane potential gradient; preventing damage to DNA.\n\nAlthough there is little doubt that antioxidants are a necessary component for good health, there is considerable doubt as to the most beneficial antioxidant(s) and as to the optimal amount for results. A study of lung cancer patients found that those given antioxidant supplements had worse prognoses. This is believed to be due to antioxidant interference with the body's normal use of localised free radicals e.g. Nitric oxide for cell signalling. Due to the complex nature of the interactions of antioxidants with the body, it is difficult to interpret the results of many experiments designed to test such things. In vitro testing (outside the body) has shown many natural antioxidants, in specific concentration, can halt the growth of or even kill cancerous cells.\n\nFor example, recent studies are suggesting that at high levels, synthetic antioxidant vitamins such as A, E and C may prove to have pro-oxidant effects: increasing the formation of free radicals. The fact that natural antioxidants are always ingested together with a wide variety of flavonoids and other phytochemicals also likely plays a part. Many supplement manufacturers supply more expensive tablets containing these. Newer liquid nutritional supplements using plant ionic compounds are believed to be more readily absorbed in the human body.\n\nThe benefits of antioxidants were examined during the Age-Related Eye Disease Study.\n\nNutritional antioxidants\nThe following substances have shown positive antioxidant effects:\n\nVitamin A (Retinol, also synthesized by the body from beta-carotene) protects dark green, yellow and orange vegetables and fruits from solar radiation damage, and is thought to play a similar role in the human body.

Vitamin E, one of the antioxidants, can be taken regularly as part of a daily vitamin and mineral supplement or spread as in an ointment on sunburn. Vitamin C is another antioxidant that will help prevent severe damage from sunburn and shorten its effects. Selenium is a mineral that will help fight sunburn.

There is no known way to prevent people from getting leukemia or any other cancer. Cancer is an ancient disease and can even be found in fossilized remains that are thousands of years old.\n\nThe History of Cancer\nhttp://www.cancer.org/docroot/CRI/content/CRI_2_6x_the_history_of_cancer_72.asp?sitearea=CRI\n\nYou can, however, minimize your chances of developing some form of cancer by not smoking, exercise, eating a well balanced diet, and remaining strong mentally and physically. Being healthy and strong when or if you get cancer definitely factors into your ability to survive cancer.

Raw food has it's own risks...  using the link below, you can determine which foods and how they are prepared, are highest in B-12\n\nVitamin B12 is an important vitamin for maintaining healthy nerve cells and it aids in the production of DNA and RNA, the body's genetic material. It also works closely with vitamin B9 (folate) to regulate the formation of red blood cells and to help iron function properly in the body. Furthermore, vitamin B12 is needed for Calcium absorption. Deficiencies of vitamin B12 are usually caused by a lack of intrinsic factor, a substance that allows the body to absorb vitamin B12 from the digestive system. Such a deficiency can cause a range of symptoms such as fatigue, shortness of breath, diarrhea, nervousness, numbness or tingling sensation in the fingers and toes. People with the blood disorder pernicious anemia do not produce sufficient intrinsic factor and must take high doses of vitamin B12 to maintain their health. Others at risk for B12 deficiency include vegetarians who follow a strict vegan or macrobiotic diet.

The craze over vitamin C's power to prevent and treat colds started with the Nobel Prize-winning chemist Linus Pauling's 1970 book Vitamin C and the Common Cold. Pauling advised taking 3,200 to 12,000 milligrams per day, far higher than conventional standards. The latest recommendation from the Institute of Medicine is 75 milligrams per day for women and 90 for men, with an extra 35 milligrams daily for smokers, who suffer higher levels of oxidative stress and cellular damage. This is a far cry from Pauling's original proposals. And studies testing Pauling's cold theory indicate that vitamin C probably does not prevent colds but may make them milder and shorten their duration.

Absolutely follow the advice of your oncologist this time.\n\nAntioxidants would protect both the normal and cancer cells. Radiation oncologists carefully plan how and where between radiation is given  to kill off the cancer cells and damage as few as possible of your healthy and normal cells.
