Am I getting adequate and appropriate care?

1 - I just learned from my oncologist that it is not part of his treatment to watch out for studies that might benefit me, other than studies by the cancer center for which he works. That leaves me to negotiate the alphabet soup of clinicaltrials.gov on my own. Not easy. Docs seem to have a conflict of interest as by referring patients to a study at another cancer center, care is transferred away from them and their employer. Shouldn't my oncologist be looking, nationally and internationally, for a study which could save or prolong my life? Is there an independent body which can assist in finding a study which is appropriate for me? 2 - I got prescriptions for PT and for a dietitian but only after I asked. Exercise, particularly when on hormone therapy, is a critical part of fighting the progression of cancer and protecting from broken bones when on hormone therapy. Likewise, diet is critical, and it's complicated, and the information from respected sources is inconsistent. Should I have to ask for those prescriptions or shouldn't the doctor independently offer them as part of comprehensive treatment. 3-The cancer center dietitian I finally saw sent me a handout created in 2020! 5 years is an eternity in PC treatment and research. The menu recommended plenty of dairy as part of a cancer fighting diet. The Prostate Cancer Foundation (PCF) recommends that dairy be consumed sparingly if at all. There is similar confusion over consumption of eggs. I have read that calcium substitutes are associated with increased progression of PC but now have to limit dairy, don't I? 4 - The doc treating me is knowledgeable but does not regularly roundtable my case with other docs and subspecialists. I get the impression that he reads my chart at the time of each appointment, and does remember me, and makes recommendations at the time, informed but without the benefit of having bounced my case off of other docs. That seems important to me. 5 - I am biochemically recurrent but no metastasis has been documented. Going back onto lupron and starting enzaludamide(sp?). Doc says I'd be better off waiting until I'm farther along before seeking a study. Is that correct? I like my doc. I have yet to get a second opinion and will at some point, but I have concerns. Thoughts are welcomed.
