Good point, though it might trigger the correlation-not-causation debate. When one has a widespread, general rise in cancer and vascular disease, one should look for a systemic cause. The general perception is changing from 'cancer is genetic' to 'cancer is environmental', although oncologists have long known it. The California Prop 65 warnings are a start at raising awareness, though more risible than alarming. I hope we start testing, treating & preventing causes, whether it's pathogens (HPV) or chemicals (benzene) causing cancer. Or other disease triggers like Alzheimer's (zoster) or ischemic event triggers (periodontal).
