So to me, is it nefarious evil corporation pollution, or just lifestyle differences, or just better detection/treatment/knowledge of cancer variations? The biggest change from now to then is obesity which is an umbrella for lack of exercise/activity, sedentary jobs and leisure time, and a vast increase in corn syrup and caloric content in eating. Environmental factors beside nuke testing might be a near-hundred-years of ICE pollution permeating the entire world, microplastics, and other pollution. Vitamin supplements may also help tumor growth. Staying indoors, aside from the exercise impact, may reduce vitamin D production from sunlight which seems to inhibit cancers as well. But eating like crap, not exercising/being active, and being fat are all not-insignificant aspects to cancer. Exercise has dozens of ancillary health benefits that can tie into cancer incidence, sugar is rocket fuel for tumors, and obesity is directly linked to cancer. I honestly hope once EVs and alt energy permeate the energy production and transportation sectors if we see a huge decline in cancer rates a decade later.
