rates nationwide. And since we are all exposed to so many chemicals, I'm sure the baseline is climbing.
The other factor that is largely ignored is the various methods that chemicals can act, and the difficulties in finding the chemicals.
I learned about this largely through the work of Pierre Beland who studies the Belugas in the St. Lawrence Seaway. But there are promoters of cancer, inducers of cancer, immunosuppressants. Promoters (if I remember right) induce mutations. Inducers cause mutations to run amuck. Immunosuppressants block the bodies normal defenses.
I believe the reason we are also seeing more strange autoimmune, and infections have to do with these same processes. I read about a woman that almost died because her dog licked a scratch. Well people and dogs have been together for a long time. Either it was a superbug (also possible) or she may be immune-compromised.
Bottom line, beware the "investigation". I did a short stint with the ATSDR and wouldn't trust the results any further than I could throw one of their buildings.
