In the absence of human studies, hundreds of recent, peer-reviewed studies have linked low level exposures of Bisphenol A, for example, to cancer, obesity, diabetes as well as reproductive and developmental harm.
Despite those links and overwhelming associations, it remains scientifically incorrect to state that BPA causes any of those maladies.
This is because “linked to” and “associated with” are not as definitive as “causes” of a disease or syndrome. Correlation does not equal causation.
Correlations — as discovered by the science of epidemiology — have often saved many lives by pointing scientists to look for the causal links for many diseases and syndromes including cholera and AIDS But epidemiology is not definitive.
