Question: do you study all the foods for things that coukld creat cancer because i believe that they could be the cause

I’m afraid I don’t study foods for cancer causing agents. What I’m looking at is ways to treat the cancer once it develops. Looking for what might cause the cancer,including,say, the possibility that some foods may increase your risk of cancer isn’t what I do. I’m looking at the other end of the disease! But there are many scientists who do.There are many reasons why cancers might develop.But it’s usually not one single cause.
