No PK, it doesn't make sense because it's my opinion, it makes sense mathematically. If a cancer patients who recieve chemo-therapy also need to pay for hospital care, due to the toxic effects of the CT treatments, which is very expensive. They also need to take many different drugs to combat the negative effects of CT on their health, which are not free and also cost a lot of money, this goes on for many years in most cases. If the patient was to receive a drug that actually cured them of the cancer they would have no need to buy more drugs, which means the drug companies would make no money off that individual. So mathematically speaking, it is more profitable for the drug companies to provide the patient with ongoing drug treatments for many years than to actually get rid of their cancer.
If you wish, I can fetch some actual statistics on the $$ involved for your information, but I don't think that's necessary.. you seem to have your own opinion. Seriously though, do you really think the CEO's of the pharmaceutical giants are a bunch of warm, fuzzy, people-loving characters who dance around and sing Kumbaia in the office during lunch-break? Get real dude.
