Who cares? There's obviously a demand for a cure for cancer. If existing drug companies don't want it somebody else will. It's not all up to drug companies.
“Somebody else will”.
Who is that somebody else?
Where are they going to get the resources to research and develop a cure?
The universities? No, too much grant money at stake.
The hospitals? No, too much money in administering treatments.
The doctors? No, too much money in diagnosis and treatment.
The government? No, too much money to be made as a parasite feeding off of all of the above.
About the only individuals that I can see willing to back a cure for cancer are the insurance companies. They’re the only ones other than yourself and your loved ones who will profit and have a vested interest in keeping you alive. If you’re looking for a group to finance the research to provide a cure, the insurance companies are the people you want to talk to.
