Dioxin body burdens in operation ranch hand veterans: promotion blocking and cancer causation

Ecotoxicology and Environmental Safety
Gary Michael Kayajanian

Abstract

The cancer incidence data from the Operation Ranch Hand Study are plotted as a function of seven dioxin body burden classifications from zero through modest levels above background. The three significant cancer incidence peaks and three significant cancer incident troughs observed are used to test a model which specifies dioxin activity as both a promoter blocker and a cancer causation agent. There is a significant, 50% reduction in total cancers other than skin at the highest dioxin body burden level compared to background. There is a significant reduction in prostate cancers in Black veterans, but not in White, as a function of increasing dioxin body burden.

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
