I have a hard time believing chemotherapy is still our best treatment for cancer.
Not everyone gets chemotherapy.. some get radiotherapy, who makes the money there? It isn't big pharma, it's the hospitals and the medical tech companies that build the machines.
Some people have surgery, who makes the money in that case? the surgeons and the hospitals.
Clearly if big pharma were to come out with a highly effective cure, they could patent it and charge whatever they want for it, and it will be the very first treatment chosen over chemo, radio and surgery. As I said, cancer will never be eliminated like polio, people are going to continually get it, and an effective treatment will make much more money than chemo drugs do today.
So the question is, what incentive would they have for holding a 'real' treatment back?
One notable advancement I read about was a radiotherapy machine that instead of firing ~3 radiation beams that converge on the tumor, it has a robotic arm that moves around the entire body firing something like 100 beams, all of which converge on the tumor. This way, very little surrounding tissue is damaged because each single beam is only 1% of the total energy but since they all converge on the tumor, it cops 100% of the radiation energy. Compared to the old machines in which 33% of the energy was delivered by each beam, this is a huge step and can allow a lot more radiation to be safely used. The machine even tracks the patient's breathing and compensates the angles. Amazing technology...
