Rumors, Myths, and Truths

We've all seen them: Facebook posts, viral emails, and blog posts that make frightening claims about cancer risk from suprising sources. There are far too many to address here, but we've listed a few of the most common. You can also see the "What Causes Cancer" page for several other commonly talked about potential risks, from cell phone towers to water fluroridation. We would be remiss if we did not mention snopes.com as a leading source for reliable information about misinformation on social media.

A viral message says plastic water bottles contain diethylhexyl adipate (DEHA), which it calls a potential carcinogen, quoting an unidentified doctor as saying women should not drink bottled water that has been left in a car because the heat and the plastic of the bottle have certain chemicals that can lead to breast cancer.

One email quotes information allegedly contained in a newsletter from Johns Hopkins University, adding that the "information is being circulated at Walter Reed Army Medical Center." Some also quote "Dr. Fujimoto from Castle Hospital" as warning that heating plastic in the microwave or freezing water in plastic bottles releases toxins, like dioxin and DEHA.
