Is There a Doctor Economist in the House?

I have a serious question, and though it may seem innocent, forgive me because sometimes innocent-childlike logic exposes some of the more fraudulent people in society.

Is breast cancer (or any cancer) curable?

The reason I ask is because, sure enough as I'm going to the hardware store, there at Caribou Coffee is in great bright pink letters, "Amy's Blend NOW AVAILABLE!!!!"

Amy being an unfortunate young woman who died of breast cancer whilst under the employ of Caribou.

The reason I ask is because like Africa, like poverty, like any other noble charity, how many billions/trillions have been spent to no avail? We cure polio, malaria, etc., etc., in relatively short order once we dedicated ourselves to it, but as time goes on, I am more and more suspicious as to whether cancer CAN be cured, or whether this is just another tragedy being taken advantage of by unscrupulous people looking to avoid real work.

So if there are any medical/biological/doctor like Cappy Cap readers that can attest to whether the cure for cancer is possible or just a scam to raise money for professional crusaders and make more coffee sales for Caribou, I would certainly appreciate it.
