Enough Walking for the Cure

Enough walking for the cure. It's time to get serious about stopping the cancer epidemic, and that means shifting activist efforts to prevention. As Devra Davis makes eloquently clear in her book, The Secret History of the War on Cancer, published last fall, cancer wasn't always common. It became common in the 20th century as chemicals of all kinds entered the food supply and the environment, and as workers were forced into contact with cancer-causing substancees. Davis offers proof drawn from unpublished research that there was clear evidence in the 1930s that cigarettes, for example, cause lung cancer. But the information was suppressed. She writes: “For nearly a hundred years, we have known that smoking, sunlight, industrial chemicals, hormones, bad nutrition, alcohol and bum luck, all affect the chance we will get cancer.”

If you want to know who the villains were, this book names them, and they include well-known leaders of cancer organizations and eminent physicians who engaged in both deliberate deceit and wishful thinking, that, for example, a safe cigarette was possible.

But don't read this book just for the history. Read it for the warnings about what we're doing to ourselves and our children. On the list of suspected and known cancer-causing agents are Ritalin, diagnostic X-rays--in particular, CAT scans being used more and more on children--cell phone use by children, and aspartame, the artificial sweetener better known as Nutra Sweet.

What we need is screening of the thousands of chemicals to which we are exposed every day.We should demand a ban on use of the chemical Bisphenol A in the linings of all canned food and beverages (Japan did so years ago) and in those clear, hard plastic baby bottles. I first wrote about this chemical in 2003, after a lab accident caused chromosomal abnormalities in lab animals. This chemical is an artificial estrogen, similar to the DES given to pregnant women in the 1970's that resulted in their girl children growing up with abnormal genitals. It causes changes in tissue that resemble early-stage breast cancer. A leading researcher, Frederic Vom Saal predicts it is only a matter of time before the FDA bans it.

Let's walk for this kind of prevention, and use the money we raise to fund real prevention efforts such as those by Davis at the University of Pittsburgh's Environmental Oncology Center.

I agree with this topic our efforts would be best placed in prevention. For some ideas on prevention, check out this brochure from the Weston A Price orgainzation:
