The nation's "cancer epidemic" was caused solely by cigarette smoking and environmental pollution played little role in it, say UAB researchers in the Jan. 1 Journal of Clinical Oncology.
In an analysis of cancer death rates going back 50 years, pathologist Brad Rodu, D.D.S., concluded, "There is no denying the existence of environmental problems, but the present data show that they produced no striking increase in cancer mortality." Isolated increases in cancer deaths may occur as geographical "clusters" due to abnormal environmental factors without having an effect on the overall cancer mortality rates. "In reality, the so-called cancer epidemic consisted of one disease, cancer of the lung, and was due to one lifestyle factor, cigarette smoking."
