ELI5: It seems like "everyone" is getting cancer. Has is always been this way, like since the dawn of time, or is this something new, or...?

I've checked *all* of the explained cancer-related ELI5s, to no avail.  
In modern times (at the present moment), it seems that cancer cases of any/all types are growing exponentially.  
  
Is this simply because better medical technology is giving us more awareness of the subject?  Or has cancer *always* been this prevalent?  ...Or?  
  
P.S. I'm sorry if I'm missing the buck here in finding the answer, or if someone has already covered my ELI5 request.
  
EDIT:  I'm going to go ahead and risk a shitstorm by saying this...but, I realize that there are "CHEMICAL ADDITIVES IN FOOD AND TODAY'S HUMANS ARE SO DUM FOR EATING THIS SHIT AND SMOKING CIGZ".  There is more to this ELI5 than your soapbox on modern man's GMO/Terrible Lifestyle.

Cancer is what kills you if nothing else gets to you first.  We've made long strides in general health and treatment of many diseases, which has caused us to live longer, which makes cancer a larger percentage of total deaths than it was further back in history.
