why can’t it be both?
Though probably McDonald’s and KFC carry most of the blame

hahahaha….chicken gain 😆
hey, by the way, talking about chicken, I think Indonesian are a really great people. Just imagine, some of the chicken butcher sells formalined chickens to be consumed and some of them do buy and eat it 😆

the old paradigm says cancer is due to mutations, or because you have a genetic deposition to getting cancer. the new paradigm says it might have to do with cell signalling.

First question:
-Is cancer really on the rise, or is it a demographic effect of longer life span and better diagnosis? Or both?
-Then you can ask what are the environmental conditions that can increase cancer prevalence: food preservatives and pesticides maybe, but you can add air pollution, smoking habits and load of other factors.
Showing a significant correlation between factors and increased camcer is already hard and need a lot of data. And a correlation is not necessarily a causation, meaning that it is not because there is ona and it is significant that there is necesarily a link between the 2. So identifying cancer causing compounds is not an easy task. And they can be all responsible to some degree.
