Cancer isn’t one thing like chicken pox; there are many different types/kinds of cancer and there is no one special bullet that will ‘cure’ it.
Tyere will never be an official pharma/medical cure for cancer because there is no profit in curing patients.
Only maintaining them as perpetual customers.
Same with cancer charities.
Now the volunteers and family members believe thats what they want. They are the plausible denial front folks big pharma/bi med/big cancer charity use for their own benefit.
