The Link Between Antioxidants and Cancer

by Holistic_Health

Antioxidants may be effective at preventing or slowing the spread of certain tumors.

There has been quite a lot of recent interest in the link between antioxidants and cancer. Studies have shown that antioxidants may be useful in preventing or even treating certain cancers. Unstable molecules within the body, known as free radicals, can cause damage to the body which can lead to tumors forming.

Antioxidants are substances found in certain foods which stabilize the free radicals and prevent damage from occurring. It is thought that these antioxidants may be effective at preventing or slowing the spread of certain tumors.

Antioxidants and CancerOther studies have shown mixed results, however, and it is thought that certain antioxidants, when given in a low dose, may actually protect cancer cells during treatment such as chemotherapy. Research indicates that repeated higher than usual doses of antioxidants may be necessary to treat cancer effectively. Given that some antioxidants are harmful to the body if the recommended daily dose is exceeded; this brings its own set of health concerns.

Generally speaking, if you intend to try treating or preventing cancer using antioxidants, you should only do so under the close supervision of a health professional. Each individual will require a different combination and dose of antioxidants and getting this wrong could cause more harm than good.

Here are some of the most common antioxidants used in the treatment of cancer. Generally speaking they are not used in isolation. Each individual may require a different combination of antioxidants.

Vitamin C

This has been found to increase the effectiveness of certain drugs used in chemotherapy, and to help prevent adverse reaction to this treatment. It can also help prevent the tumor cells spreading to other parts of the body, and has shown to be particularly effective at treating breast cancer.

Beta-carotene

This is a form of vitamin A, which boosts the immune system against the growth of tumor cells. Free radicals can damage the DNA contained in cells, which is thought to be one process which can lead to cancer. Beta-carotene decreases the damage to DNA. It is also effective at treating and preventing breast, prostate, lung, and bladder cancer.

Selenium

This can help protect the tissues from damage caused by free radicals. Many cancer sufferers have been found to be deficient in selenium. It is thought to reduce the side effects, such as headaches and nausea, which can accompany chemotherapy.

Vitamin E

This helps to strengthen the immune system; it is thought to protect normal cells from the effects of cancer treatments such as radiation, and to enhance the destruction of cancer cells.

Bioflavanoids

These occur naturally in plants such as broccoli, grapes, soy and citrus fruits. They are also found in green tea, and it is thought that the ingredients in green tea can be effective at treating cancer.

Overall, the jury is still out on the link between antioxidants and cancer, and whether antioxidants can be successfully used to treat cancer. If you decide to give this a try, you should always seek specialist advice. Generally speaking, experts agree that a diet rich in a variety of fruits and vegetables can be very effective at preventing cancer from occurring.

@Mira Yes, I've heard of those mega dose protocols. If you can get it from food that's you're first choice.

I know some people take 1,000 mg of vitamin C daily. I tried doing that to prevent colds but wasn't successful. I now tend to think you need to get it from fruit. I started eating more oranges as a result (I was already eating kiwis), among other things.

@frankbeswick Yes, seaweed is a magnificent vegetable very rich in minerals and trace elements and it is used as a fertilizer too.

Interesting about selenium, as British soils are generally low in this mineral. However, seaweed, which is high in many trace elements, might be useful diet supplement and a soil enhancer. You have reminded me to get some seaweed meal for the plot.

@frankbeswick I believe the same. Thanks for commenting!

@ Mira Appreciate the comments - thanks!

There is a remedy, I believe, for everything except old age.

Nice article. I liked your point about dosage and prevention vs. treatment. You also make good points about the various antioxidants.

@cmoneyspinner I also believe that there is a remedy for everything. Your support means a lot so thank you!

You already know that my religious beliefs are very deeply ingrained in my psyche. I've always felt like that for every illness, there's probably a natural cure out there somewhere. I think it's there by Divine Design. So I'm never the least bit surprised when medical discoveries indicate that something so pervasive as antioxidants can be effective against a horrific illness like cancer. You always write good articles.
