Absolutely! This article last spring in Scientific American — shared multiple times in the forum already — suggests that if advanced prostate cancer hasn't already shifted to being a chronic disease (one that can be managed indefinitely, like HiV/AIDS), it's getting very close:

Obviously it's just a magazine article, but I'm getting the same vibe from my medical team. They don't want to make promises yet — data is always backward-looking, and it will take years to collect enough to be sure — but there's a new confidence underlying the way they talk about our disease.

The biggest issue is that the new best practices and treatments we get at U.S. Centers of Excellence or Canadian multidisciplinary Cancer Centres haven't disseminated everywhere yet, so you might be getting old information and old treatments from some doctors at your local hospital (or not, depending on whether each individual has kept up).

Again, no promises, but it's *definitely* worth getting a second opinion from a multidisciplinary cancer research centre if your local urologist tells you you have terminal prostate cancer. The landscape has changed drastically since the 2010s.
