A new report suggests that cancer patients should not take antioxidants because they appear to protect cancer tumours against chemotherapy and radiation.

A team of North American researchers analyzed data from clinical trials investigating the effects of antioxidant supplements in cancer patients undergoing chemotherapy and radiation.

They found that antioxidants seem to protect both healthy cells and cancer cells from the damage caused by the two treatments....

what we said (Hover the mouse cursor over underlined words for more info)

This article may be unnecessarily alarming, as no evidence is provided to support the health claim it makes. There are large gaps in this report as the article does not mention treatment cost or availability and does not quantify the harms or benefits of using or avoiding antioxidant supplements. In addition, little is said about potential conflicts of interest and sources of information used to write this report.

Even though there are large gaps in the reporting of this study, readers (and patients) may still be swayed (perhaps without reason) to alter their diets and avoid antioxidants. If readers don't know what antioxidants are, they will likely worry about what foods they should avoid while receiving chemotherapy or radiation treatment. On the other hand, if readers are familiar with what antioxidants are, they will likely be concerned about the difficulty in avoiding these products during cancer treatment.

"This sounds more like another Pharma and College of Physician attack to protect their assets and their jobs because more people are seeking out these forms of therapy and having incredible successes and recoveries due to them.

Another example of how media is benefiting from the large profits of the Pharma industry at the cost of the lives of Canadians"
