> You see, cancer was a tiny spot on radar just 50 years ago. Or 100 even more. So the question is - what happened? Have we somehow changed overnight as a spices? No we haven't.
First, variety is the species of life.
Second, the reason cancer wasn't "on the radar" is because we didn't know much.
If you look into the history of cancer, it has existed forever. Wikipedia claims Hippocrate himself wrote about it! [1]
And as late as the 19th century, survival rate was around 10%.[2]
Your concerns have very little, if anything, to do with cancer. Monsanto didn't even exist in the 19th century.
