This documentary shows the history of several cancer treatments that have allegedly been supressed because they couldn't be sold, either because the intellectual property owner insisted that the formulation be in the public domain or because the substances used are food based and cannot be patented.

Plinly I am not qualified to comment on the efficacy of the these treatments, but if just oine of them is effective, then the corrupting influence of profit on human health is demonstrated and a powerful argument against the profit system is shown.
