That may not sound like much. For someone facing a terminal diagnosis, what difference does a few extra months really make, especially if the drugs that enable them cost tens of thousands of dollars, as so many cancer drugs do?
That question misses the point. In medicine, the most important breakthroughs rarely arrive all at once. They are built step by step. First, we gain a few extra months, then a few more, then years, until the disease in question is eradicated.
