I think comments are good for adding perspective. You shouldn't expect an expert to arrive and give a concise, absolutely true and exhaustive explanation with that perspective. Spurring a community to dig deeper on something previously assumed true is a good thing, right?
The article cited does not claim we've improved cancer treatments - only that mortality from cancer for certain age groups has decreased according to their analysis, which could be from a number of reasons. To my knowledge, one of those reasons is not that a variety of prevalent cancers has been cured to any substantial degree.

Especially in an active area like cancer with 10k+ papers, you can basically find a paper that will support any viewpoint.
The NYT is running a great series on cancer treatment that gets into these matters, I should have cited before, here's one of them:
