I can’t believe you think drug companies are holding back a cure for cancer. Which drug companies would those be? Do you have any proof? Do you have any idea how many good, very smart Americans are working to find the causes of and cures for cancer? And why would drug companies do that, when whoever comes up with a cure for cancer will make ba-zillions? Even if cancer were cured, there are a few other diseases and conditions needing treatment that would allow the crooked drug and biotech companies to continue to rake in their ill-gotten gains.
Cancer treatment is probably $100Billion+ per year industry, not limited to drug companies.
