I wonder how long ‘Cancer’ has been with us humans. I’m sure we’ve had it for our entire existence, but it likely went unidentified. The perceived increase of Cancer during recent decades is likely due to better detection and simply a case of people living long enough to get it, not dying of something else first. I believe I read somewhere that statistically, if a male lives long enough, Colon Cancer WILL BE what eventually kills him. Though we all know what statistics can mean.
I wonder if that’s the molecule that some dogs smell when they get freaky around somebody that does indeed have cancer.
