Episode Description from the Publisher

What if everything men are told about a prostate cancer diagnosis, biopsy first, surgery next, is built on evidence that was never actually there?In this episode of Integrative Cancer Solutions, Dr. K sits down with Dr. Stephen Petteruti, board certified family physician and author of Fight Cancer Like a Man, to break down the 2023 New England Journal of Medicine study that found no survival difference between surgery, radiation, and doing nothing at all for early stage prostate cancer. Dr. Petteruti explains why he stopped recommending biopsies, how a needle can spread the very cancer it's meant to detect, and why watching PSA and MRI trends over time is often safer than rushing into treatment. He also covers the overlooked role of testosterone in prostate cancer care, including bipolar androgen therapy, and makes the case for tracking the disease like a chronic condition instead of chasing a cure that costs a man his vitality.If you or someone you love is facing a prostate cancer diagnosis, or just navigating an elevated PSA, this conversation lays out the questions worth asking before agreeing to anything.Key Takeaways:0:00 Introduction2:33 The prostate trial that shattered the surgery-first model5:19 Why a biopsy can spread the very cancer it's meant to find8:23 Castration's hidden cost on testosterone and quality of life17:12 Tracking prostate cancer with MRI and PSA instead of biopsy21:58 Repurposed drugs and why DIY protocols backfire38:10 BAM therapy: using testosterone as a weapon against advanced cancer Schedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902Resources:Fight Cancer Like a Man (book) - https://www.intellectualmedicine.com/dr-stephen-petteruti-booksIntellectual Medicine, Dr. Petteruti's practice - https://www.intellectualmedicine.com/The Prostate Protocol - https://assets.ctfassets.net/psmhuxrqomif/4iFYGN6rh0cloFTQyxdit9/a2c3e8e20e335df0ad22f70ca0e0af48/the-prostate-protocol-pdf.pdfProtecT Trial, New England Journal of Medicine, 2023 - https://www.nejm.org/doi/full/10.1056/NEJMoa2214122Johns Hopkins Bipolar Androgen Therapy Research - https://www.hopkinsmedicine.org/news/articles/2023/12/bipolar-androgen-therapy-trials-under-way Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.
