Thank you for sharing Terry's story with us, it's very touching and heartbreaking.

Prohibition, stigma, and ignorance keep people from being able to hear and accept it, while media lies and government propaganda spin a false narrative - that surgery, pharmaceutical drugs, and radiation are the only options against the vast disease known as cancer.

This nicely summarizes what is a more serious problem than the majority realizes. That whole "hear and accept" part is tough to get past.
Prohibition, stigma and ignorance no doubt are major components, and I also think fear and ego play a role.
Many are afraid of what acceptance of such a truth would entail, with ego's fed by the narcissism induction machine.
It's just damn hard to tell people they could be wrong about something, they will defend a TV screens truth to the death. It's mind blowing.
