I see the price of proton therapy varies wildly between thousand and tens of thousands of dollars per treatment. Still too high. Perhaps if the cost were lower and some streamlined review process existed, it would be less of a lift to say “hop on the table while the accelerator spins up, won’t be expensive if this doesn’t work.” (in this example) Rationing human supply (labor) makes sense, making humans takes time and supply is constrained. Other costs can be ruthlessly driven down (with some combination of manufacturing learning, research, etc). Consider the costs of Western disease (obesity) and bariatric surgery with recent developments in semaglutide, for example.
