The reason that there “seems” to be so much more cancer in the past century is that we are living longer.
The human body’s “warranty” expires around age 45. After that, we’re on our own. That’s when the skeletal decay and the other maladies of “old age” start.
100+ years ago the average life span was mid-40’s to early 50’s. There are a few people who develop cancer under the age of 45 but it is a very small percentage of the total population.
Want to avoid cancer? Die young. That way you make a better-looking corpse too ;-)
When I got lymphoma, I was 35 :) and the only close living relative to have a cancer... we usually die of Heart Attacks... Luckily that was 7 years ago... before OCare...
I just tend to think too many artificial things going into stuff we eat and on a certain level it effects things in the body...
