It’s easy to feel cynical when so many things seem like they get stuck for ages in trials and never make it to an actual treatment, but modern medicine is truly amazing. I have family who are sadly no longer with us, but who likely would have been cured completely if they had developed the same cancer today.
> our finding showed a significant increase in breast cancer mortality rate in the world during the past 25 years ... Statistical analysis showed a significant increase for breast cancer mortality rate in all super regions, except for High-income super region. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6745227/
and for women under 40:
> Female breast cancer mortality rates have stopped declining in women younger than 40 years, ending a trend that existed from 1987 to 2010. Conversely, mortality rates have continued to decline in women aged 40–79 years. https://pubs.rsna.org/doi/full/10.1148/radiol.2021203476
I think this paper explains it: https://pubmed.ncbi.nlm.nih.gov/27175568/ "the major factors that accounted for these favorable trends were progress in tobacco control and improvements in early detection and treatment"
I feel like the treatment progress for most metastatic solid cancers have not significantly improved. A significant improvement wouldn't be just improving overall survival by a year or so. What seems possible to achieve (someday soon perhaps) is making cancer either a manageable condition, like HIV now is, or curable.
