I find the lack of accessibility to the poor for such treatment troubling. Dr. Wartman was lucky enough to work in a cancer research lab that covered the costs of the genome and RNA sequencing AND he had rich doctor friends who helped chip in to buy enough drug for him.
While the costs of sequencing are dropping quickly, medical drugs don't fall in price at the same rate. And there's always the chance that a drug to cure that particular mutation doesn't exist. What then? Spend millions on years of research to make the drug?
