Is “watchful waiting” for prostate cancer really the safest path—or could it be creating more harm than help? Today on Intellectual Medicine, Dr. Stephen Petteruti challenges the conventional use of watchful waiting and active surveillance in prostate cancer management. He argues that prostate biopsies and many standard treatment strategies often do little to improve long-term survival while subje...

In this episode of Intellectual Medicine, Dr. Stephen Petteruti challenges the conventional thinking around prostate biopsies, Gleason scores, and treatment decisions for prostate cancer. He explains why a high Gleason score, including Gleason 7, 8, or 9, may indicate a higher risk of progression but does not automatically prove that aggressive treatment will improve survival. Drawing on studies i...

In this episode of Intellectual Medicine, Dr. Stephen Petteruti challenges the common belief that a low PSA is always good news. He explains that PSA is not a cancer marker by itself, but a natural substance produced by the prostate, and that testosterone plays an important role in normal PSA production. If testosterone is low, PSA may also appear unusually low, which can create a false sense of r...

Clear thinking leads to stronger health decisions and better long-term outcomes. In this episode, Dr. Stephen Petteruti takes a closer look at common guidance around PSA testing and early prostate cancer detection, including viewpoints from Peter Attia, MD. He explains how impressive-sounding statistics can mislead, showing that a 44% relative risk reduction translates to only a 0.34% actual benef...

Strong outcomes often come from slowing down—not rushing into irreversible decisions. In this episode, Dr. Stephen Petteruti questions the automatic path from elevated PSA to biopsy, surgery, and radiation. He explains that biopsies can disseminate prostate cells, while the true impact on long-term metastatic risk remains uncertain. His approach favors sequential PSA monitoring, imaging, and disci...

Stronger, sharper years are possible when you target the source of aging. In this episode, Dr. Stephen Petteruti sits down with Chris Burris, Chief Scientist of MyVitalC, to focus on Carbon 60 (C60) and why it’s gaining attention in longevity science. This Nobel Prize–recognized molecule acts as a potent antioxidant at the mitochondrial level, helping manage the oxidative stress that drives aging...

Better health outcomes often come from slowing down and asking a harder question: is this test actually serving me, or is it serving the system? In this episode, Dr. Stephen Petteruti talks through the reality behind prostate cancer screening—what’s driving it, who’s funding it, and where the standard approach falls short. He explains how free PSA screenings are often backed by pharmaceutical comp...

Your PSA number isn't the problem. The treatment your doctor recommends for it might be. In this episode, Dr. Stephen Petteruti makes a bold, evidence-backed case against radiation therapy for prostate cancer. Drawing on the landmark ProtecT trial and other research, he explains why radiation — whether adjuvant, salvage, or seed-based — has never been shown to reduce death from prostate cancer...

Stronger outcomes in prostate cancer come from protecting vitality. In this episode, Dr. Stephen Petteruti challenges the idea that estrogen could be a meaningful solution for prostate cancer. He explains how recent studies comparing estrogen therapy to androgen deprivation focus on lowering testosterone rather than improving real health outcomes. The result? Similar survival outcomes, but at the...

Better health decisions often start with a simple habit: pause, ask questions, and understand why something is being recommended. In this episode, Dr. Stephen Petteruti talks through the reality behind many routine medical tests, what they’re meant to do, and where they may fall short. He explains how screenings like digital rectal exams, routine EKGs, bone density scans, and certain cancer tests...
