CANCER

[Roan]

It seems to me that cancer is on the rise. My big Q is: is it the amount of artificial preservatives and pesticides, or is it heavy metal contamination.

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.
