What do you want to do? Have you spoken with your Dr? How long is your trip? How old are you?
What do you mean by "my Metastatic PC"?

Are you anticipating RP or RT w/ ADT?

If the latter, then perhaps you can begin ADT (and I chose Orgovyx for Salvage Treatment) and delay RT. Note that ADT may "mess" with you in various ways.

Are you going to enjoy the travel; or be consumed with worry?

I also have noted some patients receiving ADT prior to RP.

Or, you wait until after your trip. Or you postpone the trip.

My PSA with G 9 increased from 5.6 in Dec to 7.2 at surgery in Aug. Did that allow cells to escape the prostate and become the EPE found at post-op pathology? Will never know.

Delays in diagnosis, waiting for testing and results take time and treatment schedules are often not immediate.

So would 6 - 8 weeks delay be meaningful? My initial Urological Surgeon could not schedule me for RP for 2 months. My 2d opinion Surgeon at Johns Hopkins (always my intention to go to JH if I needed treatment) had an opening in 10 days.

My point being that there can be many "delays" in the process.

Again, what is your emotional tolerance for delay?

Best wishes on your decision and treatment results.
