"Five or ten years from now there will be RNA vaccines or some other type of curative treatment for PCa. Why don’t you stick around awhile and get whatever care you can for now. Your CURE might be right around the corner."

Exactly! RNA treatment for prostate cancer is still in the lab stage, but it's not a pipe dream any more. Hang in there, everyone!

I remember reading back in 2020 that the COVID vaccines grew out of RNA research for treating different cancers. They'd already made a lot of progress, and attacking the COVID virus SARS-CoV-2 is much simpler than attacking cancers, so they were able to do a quick pivot and get the vaccines out in months instead of years/decades.

That said, for very selfish reasons I'm glad they've returned to focusing on cancers now.
