Radiation result interpretation

Posted by Roxy2017 @roxy2017, 6 days ago

How long does radiation continue to "work" after treatment?

Gleason 8 Biopsy in Jan. PET in March showed two potential bone metastases both small -- one in pelvis and one rib. Also one lymph node by prostate. Went on Orgovyx and Xtandi on 3/10. Radiation in May to prostate and node. PSA is now negligible. New PET shows no new spots and substantial reduction if not elimination in others. Will those continue to go down? Is this of concern? Will meet with radiation oncologist next week. Example: Prostate was 10.5 SUV before and is now 3.5 SUV.

Interested in more discussions like this? Go to the Prostate Cancer Support Group.

Radiation doesn’t kill everything immediately, Some people wait two or three years for their PSA to hit rock bottom after radiation . Radiation damages the cancer cells so that they start to die.

If you had a radiation to the prostate, it should have been eliminated as an issue. Was it not totally radiated? If it’s still there, it could be spreading further cancer. Then again, it could just be slowly dying as mentioned above. Ask the RO If the prostate was completely treated, If so, it’s just a matter of time.
