Chemical aside, I believe cancer is a fungus and a by product of mold exposure of any of a variety of sorts. mold's sole earthly purpose is to return biological material to the dust from whence it came. There is a type of mold which grows in insects, very much like cancer grows, until it overwhelms the insect host. That is called 'cordyceps'. Too many of the pesticides have their origin in WW I biological warfare where, although a pact was made to not use those particular things in war, they were moved over to food as pesticides.
I believe it goes beyond organic. I believe you really must try to purchase your veggies, fresh, from a nearby gardener/farmer or grow your own. The large conglomerates which have taken over organic companies, have written and rewritten their own special rules regarding organic. Just MHO.
Keep yourself well. Best healthy wishes.
