Each medical innovation overcomes but one hurdle on a path to a treatment/cure, often revealing new hurdles that weren't visible (or important) until the first hurdle fell.
A good example is lipid nanoparticles, which for the first 15 years or more of their existence were horrifically lethal in every hominid, making their potential for delivering transformative genetic or immune cargo into cells impossible. Finally, PEGylation was introduced into their formulation, bypassing the toxic effect they had in precipitating out nearly all of each animal's platelets upon treatment. Within just a few years, LNPs became a very effective way to deliver MRNA vaccines to BILLIONS of human patients, effectively ending the worst of the Covid pandemic.
Medical revolutions are like evolutionary punctuated equilibrium -- barriers to advancement are overcome nonuniformly and often incompletely, requiring a lot of continued effort even after a revolution begins. So it shouldn't be surprising that more battles are won than wars. We should celebrate whatever victories we can. Cancer promises to be a war to end all wars.
