    EpiSwitch PSE vs. PSA: Don't Spend $900 on This Test Before You Know This

    A newer prostate cancer blood test is being promoted as 270% better than PSA, but what does that claim actually mean?In this episode of the Intellectual Medicine podcast, Dr. Stephen Petteruti examines the EpiSwitch PSE test, including its potential value, limitations, cost, and the research behind the widely cited 270% figure. He contrasts the test's yes-or-no risk assessment with PSA testing, emphasizing what he sees as PSA's key advantage: the ability to track changes over time.Dr. Petteruti also discusses how men and their physicians might approach an elevated PSA, the role of prostate MRI and biopsy in conventional care, and why he believes prostate cancer risk should be viewed as a long-term management challenge rather than a single diagnostic moment. He also raises questions about the sponsorship of the study behind the EpiSwitch claims while noting that industry involvement does not automatically invalidate the research.The episode concludes with a broader message: no test should be interpreted in isolation, and results should be considered in the context of a man's overall risk, health, and long-term monitoring strategy.Timestamps:(00:00) Is the EpiSwitch PSE really 270% better than PSA?(01:12) What the EpiSwitch PSE test can and can't tell you(02:09) The cost difference between EpiSwitch PSE and PSA(03:54) Why tracking PSA over time matters(05:46) Should you consider EpiSwitch after a high PSA?(07:17) Prostate cancer as a lifetime management challenge(08:08) The test versus how the test is interpreted(08:45) What an abnormal prostate MRI can mean(09:27) Looking at the study behind the "270% better" claim(10:20) The bottom line on EpiSwitch PSE versus PSAReferences:Circulating Chromosome Conformation Signatures Significantly Enhance PSA Positive Predicting Value and Overall Accuracy for Prostate Cancer Detection- https://pubmed.ncbi.nlm.nih.gov/36765779/Enjoy the podcast?

    Prostate Cancer Surgery: You Need to Know This Before You Say Yes

    Prostate cancer surgery is a major and irreversible decision, but how much do you actually know about your surgeon’s outcomes, the risks involved, and what happens after the operation?In this episode of Intellectual Medicine, Dr. Stephen Petteruti discusses the questions he believes men should ask before undergoing a prostatectomy. He examines reported differences in urinary incontinence and erectile dysfunction outcomes, the importance of asking a surgeon for their own complication and recurrence rates, and why getting more than one surgical opinion may be worthwhile.Dr. Petteruti also discusses the role of PSMA PET imaging, surgeon selection, biochemical recurrence, and findings from the PIVOT trial. He explains his perspective on non-operative approaches while acknowledging that patients may ultimately make a different choice. The episode also addresses what happens after surgery, including postoperative planning and questions surrounding radiation therapy.Timestamps:(00:27) What doctors may not tell you before prostate cancer surgery(01:25) Understanding incontinence and erectile dysfunction rates(02:00) How to evaluate your surgeon’s actual outcomes(02:57) Asking about biochemical recurrence after prostatectomy(03:56) Why you should consider more than one surgical opinion(04:12) The role of a PSMA PET scan before surgery(05:00) Complication rates and researching your surgeon(06:10) What the PIVOT trial means for the surgery decision(07:16) Why you need a plan for what happens after surgery(08:23) Why Dr. Petteruti recommends taking time before deciding(09:59) Ask your surgeon: “Who would you choose for your own surgery?”(11:24) Considering the non-operative path and planning for recurrence(11:56) Radiation after prostatectomy: immediate or delayed?(13:01) Taking ownership of your treatment decisionReferences:Garner Health- https://www.garnerhealth.com/Biochemical recurrence after radical prostatectomy- https://www.deepdyve.com/lp/springer-journals/biochemical-recurrence-after-radical-prostatectomy-where-do-we-stand-2plJJEf6x4Enjoy the podcast?

    Make Your Body Less Friendly to Cancer: What to Eat, How to Exercise, and What Actually Matters

    What can you do every day to support your health after a prostate cancer diagnosis without allowing cancer to take over your life?This week on Intellectual Medicine, Dr. Stephen Petteruti outlines five lifestyle areas he believes deserve attention when thinking about prostate health, immune function, and long-term vitality. He begins with nutrition and protein intake, including his approach to complete proteins and intermittent fasting, before turning to sleep and why he believes obsessing over eight hours or relying too heavily on sleep trackers can become counterproductive.Dr. Petteruti also discusses walking and exercise intensity, supplements including vitamin D, zinc, vitamin C, and copper, and why more antioxidants are not necessarily better. He finishes with perhaps the most unexpected strategy: making room for pleasure and enjoyment.Rather than constantly worrying about cancer or chasing every new intervention, Dr. Petteruti encourages building sustainable habits, focusing on vitality, and continuing to live fully.Timestamps:(00:00) Five ways to make your body less friendly to prostate cancer(00:34) Why your health strategy needs to stay simple(01:28) Aging, immune function and cancer risk(03:19) Protein, nutrition and supporting immune function(04:59) Does intermittent fasting matter for cancer?(06:38) Sleep: why eight hours isn't a magic number(07:47) Walking, exercise and prostate health(09:27) Why supplements come after the basics(10:03) The antioxidant paradox: can you have too much?(12:16) Vitamin D, zinc, vitamin C and copper(14:10) The unexpected fifth strategy: fun and pleasure(15:59) Living fully without being controlled by fearReferences:Anti-inflammatory Therapy with Canakinumab for Atherosclerotic Disease- https://www.nejm.org/doi/full/10.1056/NEJMoa1707914?referer=https://www.google.com/&Chapter 15 - Exercise, Immunity, and Illness-https://www.sciencedirect.com/science/chapter/edited-volume/pii/B9780128145937000153The immune hunger games: the effects of fasting on monocytes-https://pmc.ncbi.nlm.nih.gov/articles/PMC10541887/Enjoy the podcast?

    He Refused Surgery. One Year Later, Doctors Couldn't Explain the MRI

    What happens when a man diagnosed with prostate cancer decides not to undergo surgery or radiation?In this episode of the Intellectual Medicine podcast, Dr. Stephen Petteruti shares the true story of a 51-year-old patient diagnosed with biopsy-confirmed prostate cancer who chose a different path. After years of active surveillance, repeated MRIs, and multiple biopsies, the patient sought an alternative approach designed to monitor his cancer without additional biopsies while focusing on preserving his health and quality of life.Dr. Petteruti explains the rationale behind his non-biopsy monitoring protocol, which combines advanced imaging, lifestyle modification, nutritional strategies, and carefully selected repurposed medications. He discusses how the patient's MRI findings improved dramatically over time and why those results should be interpreted cautiously rather than viewed as evidence of a cure.Throughout the episode, Dr. Petteruti also explores the limitations of PSA testing, the role of PSMA PET imaging, and the importance of understanding all available treatment options before making life-changing decisions. Prostate cancer management should aim not only to control the disease but also to preserve vitality, function, and quality of life.Timestamps(00:00) Diagnosed with prostate cancer at age 51(01:15) Active surveillance and the burden of repeated biopsies(02:40) Introducing a non-biopsy monitoring approach(04:10) Building a protocol: repurposed drugs, lifestyle, and nutrition(05:45) MRI changes from PI-RADS 4 to PI-RADS 1(07:00) Why this is not evidence of a cure(07:45) PSMA PET scan: looking beyond the prostate(08:25) Why PSA alone doesn't tell the whole story(09:20) Preserving vitality while managing prostate cancer(10:25) Why patients deserve more than two treatment optionsEnjoy the podcast?

    Fauci Pleaded the Fifth (111 Times!)... Medicine Still Hasn’t Learned Its Lesson

    Should patients always trust the experts, or should they ask more questions?This week on the Intellectual Medicine podcast, Dr. Stephen Petteruti reflects on the broader lessons that medicine can learn from the COVID-19 era. Using recent headlines surrounding Dr. Anthony Fauci as a starting point, he explores larger questions about medical authority, patient autonomy, and the role of healthy skepticism in healthcare.Dr. Petteruti discusses how uncertainty is an unavoidable part of medicine and argues that clinicians should acknowledge the limits of what they know while empowering patients to participate in important healthcare decisions. He also examines how institutional dogma, fear, and emotional pressure can influence decision-making, emphasizing the importance of distinguishing evidence from opinion.Drawing parallels between pandemic policies and other areas of medicine, including prostate cancer care, Dr. Petteruti explains how prioritizing a single outcome can sometimes compromise a patient’s overall health and quality of life. He concludes by encouraging informed patients to ask thoughtful questions, seek reliable evidence, and take an active role in decisions about their care.Timestamps(00:00) The cost of losing personal freedom during the pandemic(00:45) Who should make healthcare decisions?(02:25) Dogma, certainty, and the limits of medical expertise(03:00) Why patients should remain in control of their medical choices(05:00) The dangers of emotional coercion in healthcare(06:35) Healthy skepticism versus cynicism(08:35) Why medicine must treat the whole patient, not just one problem(10:30) What the COVID era can still teach modern medicine(11:50) A final message: ask good questions and verify what you're toldEnjoy the podcast?

    MRI vs. Biopsy: Which Should Come First?

    An elevated PSA often leads to an important question: should you have a prostate biopsy right away, or is an MRI the better first step? In this episode of Intellectual Medicine, Dr. Stephen Petteruti explains why multiparametric MRI has become an essential tool in evaluating men at risk for prostate cancer before proceeding to biopsy.Dr. Petteruti discusses how MRI helps identify suspicious areas within the prostate, the role of the PI-RADS scoring system, and why imaging can provide valuable information that guides decision-making. He also explains the limitations of prostate biopsies, including sampling error and the challenge of drawing broad conclusions from a relatively small tissue sample.The conversation explores how PSA trends, MRI findings, and clinical judgment work together to determine the most appropriate next steps. Dr. Petteruti also discusses active surveillance and emphasizes the importance of patients understanding their diagnostic options so they can make informed decisions in partnership with their physician.Timestamps(00:00) Elevated PSA: What's the next step?(00:55) Why MRI often comes before biopsy(01:45) What a prostate MRI can reveal(02:20) Understanding the PI-RADS scoring system(03:15) Why targeted biopsies have limitations(05:20) What a biopsy can and cannot tell you(07:20) Understanding Gleason scores and cancer grading(09:15) When active surveillance may be appropriate(11:10) Monitoring PSA and MRI over time(12:20) Becoming an informed patient and making confident decisionsEnjoy the podcast?

    Can Stress Make Prostate Cancer Worse? The Truth About Fear and Cancer

    A prostate cancer diagnosis can bring uncertainty, fear, and stress, but does stress actually make cancer worse? In this episode of the Intellectual Medicine podcast, Dr. Petteruti explores the relationship between stress, mindset, and prostate cancer. He explains the difference between healthy, action-oriented stress and chronic fear, which can diminish the quality of life.Rather than focusing on eliminating stress altogether, Dr. Petteruti encourages listeners to channel anxiety into meaningful action, make informed treatment decisions, and avoid letting cancer dominate every aspect of their lives. He shares personal stories and practical strategies for breaking cycles of worry, maintaining vitality, and preserving a sense of purpose throughout the cancer journey.The discussion also highlights the importance of finding joy, planning meaningful experiences, and avoiding "hedonistic deprivation," the loss of life's simple pleasures in the pursuit of perfect health. Ultimately, this episode is a reminder that while cancer may be part of your life, it doesn't have to define it. By prioritizing vitality, reducing unnecessary fear, and focusing on what you can control, you can improve both your well-being and your outlook.Timestamps:(00:00) Does stress really make cancer worse?(01:03) Healthy stress vs. chronic stress(05:10) A different way to overcome fear(08:45) Don't let cancer beat you twice(10:42) Practical ways to reduce stress(12:48) Why joy is part of your treatment plan(14:20) Planning for happiness while living with uncertainty(15:24) Don't let cancer become your identity(16:41) Living without regret(17:45) Why stress has always been part of the human experienceEnjoy the podcast?

    Can You Starve Cancer? The Warburg Theory And What You Should Know About Extreme Diets

    Can cancer really be "starved" through diet?  In this episode of the Intellectual Medicine podcast, Dr. Petteruti takes a closer look at the Warburg Theory and the growing interest in cancer metabolism. He explains why the popular idea that cancer can simply be "starved" by cutting out sugar or following an extreme diet is an oversimplification and explores the critical role mitochondria play in both cellular health and cancer development. The conversation delves into how mitochondrial dysfunction, aging, and metabolic stress may influence cancer risk, while distinguishing between promising laboratory research and what current clinical evidence actually supports. Dr. Petteruti also addresses common misconceptions about sugar, glutamine, meat consumption, and ketogenic diets, emphasizing that nutrition should be personalized—not shaped by fear or internet trends. The episode concludes with practical strategies for improving metabolic health, including managing insulin resistance, avoiding excessively large meals, maintaining a healthy body composition, and supporting mitochondrial function. Rather than presenting metabolism as a cure for cancer, Dr. Petteruti explains how optimizing metabolic health may complement conventional cancer treatment as part of a comprehensive approach to patient care.
