You are getting very bad advice from your oncologist! Pluvicto has been approved by the FDA for several years for commercial use, after many years of clinical trials and peer-reviewed publications. Second, it is no longer a requirement to undergo chemotherapy before Pluvicto. You need to find a new oncologist ASAP. This one is either not current on prostate cancer treatments or doesn't want to bother getting up to date. Run, don't walk, away!
