Hi,
I'm sorry to hear that your husband is still suffering.
I cannot help or advise on whether it would be best to wait for the CT scan results before making travel arrangements. I just wanted to bump the conversation, as I know there are others on here in a similar predicament, that may be able to assist.
I agree that PSA levels aren't always a good indicator. Mine was only 6, but I was Gleason 9 (4+5)
I hope his scan results are favourable.
Bigs hugs to you both.
