Continue learning all that you can; you’ll find that this journey you’re embarking on is much about self-advocacy and shared decision-making. There will be no one-size-fits-all solution.

You’ll be wanting to know more about the aggressiveness of your prostate cancer:
> Regarding your PSA of 13.4, do you know your PSA Doubling Time?

> Regarding your MRI/biopsy, is there any mention of cribriform pattern, perineural invasion, intraductal carcinoma, extracapsular extension, or seminal vesicle invasion in the MRI of biopsy reports?

> Regarding your PSMA PET scan, what were the SUVmax scores assigned to each of the lesions?

Next steps will be to keep asking questions and get further tests to further determine aggressiveness. Treatments can wait until you learn more fully about what you’re dealing with.

Yes, much to read, study, and prepare for. If you can find a local in-person prostate cancer support group, you should join one. There’s much value in face-to-face discussions. Otherwise, there are many virtual support groups.
