First steps would be to get a PSMA PET scan to see if there’s metastasis that can be zapped with SBRT radiation.

The next step would be to go on ADT and an ARSI (Zytiga or a lutamide) To suppress whatever there is and stop it from growing.

If many metastasis are found Then chemo or Pluvicto Could be used.

You should definitely have genetic testing to see if you’ve got a genetic problem. You can get it done for free here.

Don’t say you want your doctor involved when filling out the form online or they won’t send you the kit until they speak to your doctor. If certain genetic issues are found there are drugs for them specifically.

Did your husband get a decipher test? It will show the likelihood of the cancer coming back. Definitely speak to your doctor about that.

All of the steps mentioned will be done in coordination with a doctor or even more than one doctor.
