Also, "X deaths haven't improved" misses the point that everyone dies and the population is aging.
This is the thing with female heart disease. Some people are saying "for too long men have gotten all the attention about heart disease. It's sexism!" When in fact, the point is that men died from heart disease at a young age overwhelmingly more often than women. Some men also get breast cancer, but we don't see mandatory breast cancer screening for men, and it's not "sexism against men" it's just prioritizing who gets screening due to costs.
But we treated the male heart disease problem pretty well, so men are tending to live longer and are thus relatively more likely to die of other causes, so we can talk about a "rise" in prostate cancer. When it's purely because something else didn't get you first. Naturally, if all the fixable diseases are fixed then eventually everyone will have a 100% death rate from those things we can't fix. "100% of the population dies from pancreatic cancer. What is the cause for this epidemic?!?" reads the tabloid headline. The "epidemic" was caused by curing every other disease.
And for women, we tackled the diseases mostly likely to kill them, so naturally they lived longer, and other diseases, such as heart disease therefore increased in "frequency" of being the cause of death. Since deaths always add up to 100% you're always going to have a "big killer" with a similar percentage no matter how good medicine gets.
