Prostrate cancer in lungs that are subcentimeter in size?

Hi my father had stage 4 prostate cancer spreaded to thd bone in the year 2023 but recently found it had spread to the liver. Can you share your treatments that worked for you

Yes, ADT/Hormone Therapy, and spot radiation have worked well along with quarterly oncology monitoring. Prayers for you and dad.

Enz bitraterone chemo Radiun 223 all failed PSA jumped to 424 up 20

Hvequalified for LU 177 but it may not work

Doc said may have 6 months to live

PSMA PET scan in 2/24 showed a small lung nodule. Follow-up 6 month CT scans in 8/24 and 1/25 show the nodule still there but it has been stable (4mm). My Drs have not expressed concern and the radiology impression is that it's probably benign and probably infection. But if it's "infection", wouldn't it go away by now. I've got another 6-month CT tomorrow. My PSA has been < 0.01 for 2 years. But, I've learned that neither PSA or PET are always reliable. I've read it's highly unlikely to have metastasis to the lungs without it already showing up somewhere else first?

Several years ago I read something about prostate cancer in the lungs, but it was never a stand alone and had always metastasized from somewhere else and most prostate cancer in the lungs was only discovered post mortem. The only (more favorable) way to determine if these sub centimeter lung nodules are cancer would be via a needle biopsy not a PSMA. My lay opinion is that the nodules are not cancerous and I would not begin cancer treatment until several of the nodules were subject to a biopsy.
