The Link Between Antioxidants and Cancer

Other 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.
