Hi Marlene, He is not alone, almost everyone is dismissed by doctors for toxic exposures that either take decades to show damage or from a synergistic effect of being exposed to multiple toxins in a short period of time. The very concept of synergistic effect is controversial because it has not been tested and the effects have not been documented over the periods again of decades that it might take for symptoms of damage to manifest.A synergistic effect that leads to a type of cancer that usually takes decades to emerge after an exposure but manifests itself much sooner than if it was a single toxin exposure is also controversial and not accepted by most doctors. The rebuttal to that is treat the disease taking into account that it may well have been from an exposure to a toxin because we dont have the time to wait decades to prove it. Case in point the man they describe in the article who was vindicated after he was dead. Also way too common.
