Antioxidant Supplements for Cancer Survivors

Antioxidant and cancer prevention -

Tuveson, who is a practicing cancer doctor as well as a renowned researcher, says that you can trace the idea that antioxidants ward off cancer all the way back to famed chemist Linus Pauling, who wrote a book on it in The truth is, we need reactive oxygen—a type of oxidant, and therefore a source of free radicals—in order to live.

Tuveson explains that reactive oxygen is essential in a variety of bodily processes. It helps ensure that our cells manufacture proteins properly.

Our immune system uses it to kill invaders. The image shows organoids blue grown from pancreas cells. Healthy cells maintain a fine balance of antioxidants and oxidants. When cells divide, they make a lot of reactive oxygen, because making new cells involves many of those processes for which reactive oxygen is essential.

Following division, cells then use antioxidants to neutralize the excess reactive oxygen. They must restore the balance in order to keep growing. This is called synthetic lethality: discovering conditions that are harmful to cancer cells but not healthy cells. Based on the encouraging results of this study in organoids, lowering antioxidant levels within cancer cells could be one way to do this.

This does not tell us the effect that eating antioxidant-rich foods has on cancer, however. That remains an active area of research with many unanswered questions.

This is why the Linus Pauling case is so important. When he wrote that book, no one had shown that taking vitamin C orally would have those same cancer-killing effects observed when it was administered by IV—in fact, taking lots of vitamin C orally can harm health. It turns out that if you give people antioxidants around the time that they exercise, which can be as simple as a big glass of orange juice, you neutralize the positive benefits of exercise.

Earlier studies of antioxidant supplement use by people have also hinted at a cancer-promoting effect. A large trial reported in that daily megadoses of the antioxidant beta-carotene increased the risk of lung cancer in male smokers by 18 percent and a trial was stopped early after researchers discovered that high-dose beta-carotene and retinol, another form of vitamin A, increased lung cancer risk by 28 percent in smokers and workers exposed to asbestos.

More recently, a trial involving more than 35, men over 50 found that large doses of vitamin E increased the risk of prostate cancer by 17 percent. These findings had puzzled researchers because the conventional wisdom is that antioxidants should lower cancer risk by neutralizing cell-damaging, cancer-causing free radicals.

But scientists now think that antioxidants, at high enough levels, also protect cancer cells from these same free radicals. Last year the scientists behind the melanoma study found that antioxidants fuel the growth of another type of malignancy, lung cancer.

Free radicals are highly reactive chemicals that have andd potential to harm Antioxidajt. They are created when prevenfion atom or a molecule a chemical that has Antioxidant and cancer prevention or more atoms either gains Preention loses an Antioxidant and cancer prevention a small negatively charged Sustainable power systems found in atoms. Free radicals are formed naturally in the body and play an important role in many normal cellular processes 12. At high concentrations, however, free radicals can be hazardous to the body and damage all major components of cells, including DNA, proteins, and cell membranes. The damage to cells caused by free radicals, especially the damage to DNA, may play a role in the development of cancer and other health conditions 12. Abnormally high concentrations of free radicals in the body can be caused by exposure to ionizing radiation and other environmental toxins.
