In this episode, Dr. Geo is joined by Dr. Steven Freeland to discuss the powerful intersection of urologic oncology and metabolic health. Dr. Freeland shares groundbreaking research on how dietary interventions—specifically low-carbohydrate protocols—can slow prostate cancer progression and counteract the metabolic damage caused by standard treatments like Androgen Deprivation Therapy (ADT).

1. The Metabolic Growth Signal: Why insulin and Insulin-like Growth Factor 1 (IGF-1) are considered "fuel" for prostate cancer cells and how reducing sugar can starve that signal.
2. The 20-Gram Protocol: Insights from Dr. Freeland’s study on ultra-low-carb diets, where participants saw a 20-pound weight loss and a significant slowing of PSA doubling time.
3. Combatting ADT Side Effects: How a metabolic approach can improve insulin resistance by 30% and surprisingly help preserve bone density during hormone therapy.
4. The "Slim-Fat" Reality: Why your BMI might be normal, but your visceral fat (adiposity) could still be driving inflammation and cancer growth.
5. Clinical Markers to Watch: Why patients should ask about HOMA-IR (Insulin Resistance) and Hemoglobin A1C rather than just focusing on PSA alone.

1. Dr. Steven Freeland: Cedars-Sinai Faculty Profile
2. Research Paper: Ultra-low carbohydrate diet and prostate cancer progression (referenced as the "20-gram study").
3. Recommended Diet Protocol: Induction Phase Atkins (as used in the clinical trials).
4. Clinical Markers: * HOMA-IR: (Fasting Insulin $\times$ Fasting Glucose) / 405 (or 22.5 in SI units).
5. Hemoglobin A1C: A 90-day average of blood sugar levels.
6. Wearables: Fitbit, Oura Ring, and Whoop (discussed in the context of tracking "active steps" and sleep quality).

Is the biopsy needle more dangerous than the cancer itself? In this episode, Dr. Geo sits down with Dr. Mark Emberton, Dean of Medical Sciences at UCL and a global leader in urologic oncology. We dive deep into the "See and Treat" revolution—a massive shift in prostate cancer care that moves away from "blind" invasive biopsies toward precision imaging like MRI and PSMA PET scans.

Dr. Emberton explains why many prostate cancers found through traditional methods are "biological non-events" that never needed treatment, and how younger men (ages 40-50) can better navigate their diagnosis. We also discuss the future of focal therapy, the role of AI in radiology, and the groundbreaking "Transform" study that aims to change prostate screening forever.

WHAT YOU'LL LEARN IN THIS EPISODE:

✅ Why a normal MRI (PI-RADS 1-2) might mean you can skip the biopsy entirely.

✅ The difference between "visible" tumors on imaging vs. microscopic disease.

✅ How PSA density acts as the crucial "tie-breaker" for indeterminate results.

✅ The future of "See and Treat": Targeting lesions while avoiding surgery side effects.

✅ Why tumor location (Anterior vs. Posterior) changes your treatment options.

✅ How AI and new magnets are making MRI screening cheaper and faster.

If you’re 55, 60, 65+ and dealing with low energy, low libido, ED, or you’ve been told testosterone therapy (TRT) is dangerous for prostate cancer—this episode is for you. Dr. Geo sits down with Dr. Abraham Morgentaler (Harvard-trained), founder of the first comprehensive Men’s Health Center in the U.S., co-founder of the Androgen Society, author of the bestseller Testosterone for Life, and winner of the 2024 Grandmaster in Testosterone Award.

In this conversation, Dr. Morgentaler explains how the old “testosterone causes prostate cancer” dogma took hold, why it’s being challenged, and what men should understand today about:

✅ TRT and prostate cancer (past, present, and what’s changing)

✅ Why FREE testosterone matters more than total testosterone for symptoms

✅ The importance of listening to patient symptoms, not just “a number”

✅ Testosterone options: injections, gels/creams, pellets, oral testosterone

✅ What men should ask their doctor if they have low testosterone, active surveillance, or history of prostate cancer treatment

This episode is educational and designed to help you walk into your next doctor’s visit with better questions and clearer understanding.
