The incidence of prostate and breast cancer is up, but that's only because there's more early detection. In the 1980s more men starting getting PSA tests, and more women had mammograms. Lung cancer increased in women because more women took up cigarettes, and skin cancer increased because of lunatic sunbathing. But overall cancer rates have not been rising, and lots of cancers, like stomach, uterine, and colorectal cancer, are on the decline.
We think there's a cancer epidemic because we hear more about cancer. Cancer is a disease of an aging population, and fortunately, more people now live long enough to get cancer. More talk about it too. Many years ago people who got cancer were secretive about it.
The other big reason we think there is an epidemic is that the media, suspicious of chemicals, hype dubious risks.
Almost every week, there is another story about a potential menace. Reporters credulously accept the activists' scare stores: While I've been a reporter, I've been asked to do alarmist reports about hair dye, dry cleaning, coffee, chewing gum, saccharin, cyclamates, NutraSweet, nitrites, Red No. 2 dye, electric blankets, video display terminals, dental fillings, cellular phones, vaccines, potato chips, farmed salmon, Teflon, antiperspirants, and even rubber duckies.
I refused to do most of those stories, and now I have to ask, if the scares were valid, where are the bodies? If one-tenth of what the reporters suggested was happening did happen, there would be mass death. The opposite is true: Despite exposure to radiation and all those nasty new chemicals, Americans today live longer than ever.
The media hysteria may be nonsense, but our fear is real-and contagious. That can be deadly.
MYTH: DDT causes all kinds of cancers, and nearly wiped out every bird in the world.
TRUTH: DDT saves lives.
Malaria will kill more than one thousand children before you finish reading this book. The chemical DDT is at the core of the problem-not the use of DDT, but the failure to use it because of media hysteria. In Uganda alone, said minister of health Jim Muhwezi, "We are losing between two million and three million people a year." Think of it: Millions die because the media gets it wrong.
You are probably saying, "What is he talking about? DDT is awful!" But it isn't. DDT is capable of doing far more good than harm. You just don't know that, because some people, including reporters, are terrified of DDT.
Here's how it happened: Fifty years ago, Americans sprayed DDT everywhere. Farmers used it to repel bugs, and health officials to fight mosquitoes that carry malaria. Nobody worried much about chemicals then. It was a shock to watch the old videos my producer found: People at picnics just sat and kept eating while trucks sprayed thick white clouds of DDT on top of them. In fact, when the trucks came to spray, some people ran toward them-as if an ice cream truck had come-they were so happy to have mosquitoes repelled. Tons of DDT were sprayed on food and people.
Despite this overuse, there was no surge in cancer or any other human injury. Scientists found no evidence that spraying DDT seriously hurt people. It did cause some harm: It threatened bird populations by thinning the shells of their eggs.
