Americans are exposed to a large number of known and suspected cancer-causing or promoting agents. Nearly three-quarters of all cancers in the U.S. are thought to be attributable to diet, smoking, occupation, natural radiation and alcohol. Because most of these factors involve voluntary actions, many cancers may be preventable. For instance, studies have suggested that diagnostic X-rays of pregnant women may have doubled the risk of their children developing cancer. Radium contamination of drinking water may also double the risk of leukemia.
Smokers have at least a ten-fold increased risk of lung cancer.
Even nonsmoking spouses of smokers may, on average, have a 1.3 times increased risk of lung cancer. One study suggested that children with one smoking parent, had 1.7 times increased risk of leukemia. If both parents smoked, the risk increased to 4.6 times. We live in a culture with many factors which contribute to increased risk of cancer. Scientists cannot now conclude that EMF are among them.
