You really need to get a second opinion from a center of excellence. Sounds like the doctor you’re going to is not keeping up. You should have been given salvage radiation when your PSA hit .2. That could’ve prevented the spread of cancer that you now have. Leaving it go past .2 is very risky and the doctor that would do that should not be the one that you wanted to depend on for your care.

You now have a serious case of cancer and you may need chemo or Pluvicto.

They are not considered infected. They are tumors called metastatic prostate cancer.

If you have more than five of them, then chemo is usually what is done.

Please find yourself a center of excellence and get yourself a better doctor to handle your care.
