“In 1964, when I was five years old, two senior scientists at the National Cancer Institute, Wilhelm Hueper and W. C. Conway, looked at the data on cancer trends available to them at the time and concluded: “Cancers of all types and all causes display even under already existing conditions, all the characteristics of an epidemic in slow motion.” This unfolding crisis, they asserted, was being fueled by “increasing contamination of the human environment with chemical and physical carcinogens and with chemicals supporting and potentiating their action.” And yet the possible relationship between cancer and “the growing chemicalization of the human economy” has still not been pursued in any systematic, exhaustive way.”
