Good question Hannah. Just my two cents worth my grandma's era. They grew up in the depression and had little access to rich foods like meat and dairy so maybe as time progressed and food became more available coupled with the introduction of antibiotics in meats as well as chemicals in the foods/grains animals are fed then not only do we in turn consume these poisons in our meat but all subsequent dairy products too. Cancer incidence growing alongside the above mentioned?...

I agree 100%.
