    38. Medicine’s War on Sunlight: more casualties than global shooting wars?

    What if our obsession with “dangerous” sun exposure is killing us? If you (recklessly) leave your urban office for lunch, you are told to yank your hat down low. If you (again, recklessly) let your kids dash into the backyard, you are told to slather them in sunscreen—or learn to live with the guilt. And yes, sun avoidance undoubtedly prevents some skin cancers, including the deadliest type, melanoma But a recent study suggests lack of sunlight contributes to hundreds of thousands of deaths every year in the United States alone,  This is orders of magnitude more than the estimated 8400 annual deaths from melanoma. In this episode, we discuss evidence linking sun avoidance to almost a million annual deaths in the US and Europe alone, four times more deaths than caused by all the shooting wars, globally, each year.increased risk of breast, pancreatic, colon, and lung cancers, as well as heart disease, high blood pressure, and strokeand, perhaps most surprisingly, to INCREASED risk of death in those already diagnosed with sun-induced melanoma.Yes, you read that right; some melanoma deaths may be related to too little sunlight.  (But do understand that this is complex--sunlight DOES cause melanoma. Well, some melanomas are not caused by sun exposure, and we discuss those....) Lack of sun exposure is not fixed by taking vitamin D, unfortunately. We explore the evidence that supplementing with vitamin D pills fails to remedy these terrible conditions, and what a thoughtful person can do instead, while staying safe. We hope you enjoy this episode, and that it helps you enjoy the sun again--thoughtfully, of course.  References and further reading:   Sunlight: Time for a Rethink?Benefits of oral Polypodium leucotomas extract in MM high risk patients (This is an ingredient in Life Extension’s Shade Factor, mentioned in this episode by Dr. Gordon). Uses of Polypodium leucotomos Extract in Oncodermatology  Calzari et alInsufficient Sun Exposure Has Become a Real Public Health Problem.

    37. Why Cancer Treatments Stop Working—and How Killing More Cancer Cells Can Make It Worse

    Cancer treatment is simple, right? Kill as many cancer cells as possible, as quickly as possible. In some cases, that may be exactly the wrong approach. In this episode, Dr. Dawn Lemanne and Dr. Deborah Gordon explore a surprising idea emerging from evolutionary biology, ecology, and mathematical oncology: in some metastatic cancers, aggressive treatment may unintentionally accelerate the growth of treatment-resistant cancer cells. Using examples ranging from DDT-resistant boll weevils to metastatic prostate cancer, they discuss: • Why cancer treatments stop working in advanced cancers • How cancer cells evolve resistance • How treatment-sensitive cancer cells actually help control more dangerous treatment-resistant cancer cells  • The concept of "competitive release" and how treatment can unintentionally remove the competition that restrains resistant cancer cells • How new blood tests called circulating tumor DNA (ctDNA) allow physicians to monitor cancer in real time • The emerging field of adaptive cancer therapy, in which treatment intensity is adjusted in response to the cancer's evolutionary behavior • The research suggesting that overtreatment can sometimes shorten, rather than prolong, cancer control Along the way, they explore groundbreaking work mathematical oncologists and cancer evolution researchers, and discuss a radically different way of thinking about advanced cancer—not simply as an enemy to destroy, but as an evolving ecosystem whose behavior may be influenced and, in some cases, steered. This conversation applies to advanced metastatic cancers that cannot be cured with current treatments. It does not challenge the importance of aggressive treatment for cancers that remain potentially curable. The question explored in this episode is simple: Can killing more cancer cells sometimes make cancer worse? Dawn Lemanne, MD Oregon Integrative Oncology Leave no stone unturned.

    36. Andy Baxter: Lift Heavy but Let It Down Easy

    In today's episode, we welcome back a familiar and popular guest, Andy Baxter, who has an impressive resume as rower, rowing coach, and particularly insightful rehabilitation specialist. What Dr. Lemanne and I have particularly appreciated about his work is his focus on not just rehabbing an injury, but going beyond rehab.  He is a master at how to safely build both strength and resilience, good for avoiding both dementia and cancer. He'll talk about about his exciting new and innovative techniques for achieving those goals. Welcome back, Andy! Dawn Lemanne, MD Oregon Integrative Oncology Leave no stone unturned.

    35. Hormones Reconsidered: What We Got Wrong About Estrogen, Risk, and Replacement

    In this episode, we’re joined by Debra Zaslow—author and storyteller—who shares her personal experience with hormone replacement therapy, including some immediate and unexpected effects that took her by surprise. From that starting point, we explore several unexpected ideas:  Estrogen alone may reduce breast cancer risk in certain groups  Not all “progesterone” is the same—synthetic versions can behave very differently  The way a hormone is delivered (pill vs patch vs topical) can significantly change its effects  Hormones are often prescribed without measuring levels—unlike almost every other hormone in medicine  Many key hormones, including estrogen and testosterone, are made from cholesterol Dr. Deborah Gordon and I revisit hormone therapy in response to your strong interest in the topic. The conversation moves from lived experience to clinical nuance—how different formulations behave, why dosing and monitoring matter, and how to think more precisely about risks and benefits, especially in menopause and in more complex settings like cancer history. A candid, grounded discussion for anyone trying to make sense of hormones beyond the headlines. Dawn Lemanne, MD Oregon Integrative Oncology Leave no stone unturned.

    34. Brain Expert Tommy Wood: Retirement is bad for your brain, unless you do THIS!

    In today's episode, we have the distinct pleasure of speaking with Dr. Tommy Wood, whose new book, The Stimulated Mind, will be available soon. We explore his concept of developing greater head space. That's not hat size, but rather our cognitive reserves as we head into older age. We talk about the kinds of brain training and brain resting that are most helpful for our brain health and function. Dr. Woods also talks about his work coaching elite athletes. He shares his insights about getting better results when we remember compassion, both with ourselves and with others. One fascinating item is we learn why an experiment that put glasses--eye glasses--on owls shows us the one missing ingredient that makes it difficult for aging brains to learn. And more importantly, how one specific simple change in attitude turned old owl brains into spring chickens, forgive the pun, able to learn as easily and as well as young owls. Join us for a fascinating discussion and a preview of Dr. Wood's forthcoming book, The Stimulated mind. Enjoy. Dawn Lemanne, MD Oregon Integrative Oncology Leave no stone unturned.

    33. Ultra Processed Foods, is there a simple solution?

    In today's episode, we explore the controversy regarding ultra-processed foods, starting with an attempt to define just what those are. That's actually not been carefully approached yet. Then we look at the more serious attempts to construct ways to measure and precisely discuss the hazards of ultra-processed foods and ways we might rectify those. We range far afield from our esoteric medical school lectures all the way back to our own childhood eating experiences. We talk about the role of wise choices with any foods, including fast foods. And yes, you can eat those wisely or less wisely. We circle back several times to the importance of some basic home cooking skills and habits. We invite you to listen to this episode and enjoy.   Dawn Lemanne, MD Oregon Integrative Oncology Leave no stone unturned.

    32. Exercise: the good news and ... bad?

    In this episode we discuss one of our favorite pasttimes – exercise—and the relationship between exercise and health. Of course it’s no surprise that exercise is recommended for its health benefits, for people at any age and any level of fitness.  Dr. Gordon and I both prescribe exercise as one of the most important parts of our routine patient care.  Today though we dive into what has surprised us both:  the hazards of ??too much?? exercise.   When might exercise have a dark side, when should we think twice about our exercise habits? And how might we tweak our exercise routine to get the most benefit from the time we do spend being active. Join us as we pore over some of the details.

    31. Rewiring Risk: Fixing ADHD Decreases Alzheimers, Social Jet Lag Ups Cancer Risk, and a theoretical strategy to treat prostate cancer

    Treat ADHD, lower Alzheimer’s risk? The episode explores emerging evidence that simply having ADD/ADHD raises lifetime Alzheimer’s risk—yet appropriately treating it in adults, often with low-dose stimulants, seems to push that risk back down. How can the same class of drugs be both feared as “brain-burning” and yet potentially brain-saving—and what does that mean for people already in midlife? Treating prostate cancer successfully with--testosterone?  Listeners are introduced to a first-in-oncology “directed evolution” case in metastatic prostate cancer, led by Dr. Lemanne’s team, where high-dose testosterone was deliberately used to expand treatment-sensitive cells—and only then was hormone blockade re-introduced. But did this radical, counterintuitive maneuver actually work? Emotional trauma in youth as a hidden Alzheimer’s driver? Dr. Gordon discusses links between youth emotional trauma to higher rates of Alzheimer’s decades later, even in people who appear to have “moved on.” Is this just correlation, or should early emotional trauma be considered a subtle form of brain injury that can and should be addressed? Do you go to bed later on weekends, by just 1-2 hours, but make up for it by rising later?  If so, you'll want to know that you may be increasing your risk of breast or prostate cancer.  This episode explores that research. Have you heard of the new Alzheimer’s blood tests, that improve as the patient improves, allowing better direction of treatment?  Dr. Gordon walks us through the ATN panel (amyloid-beta, p-tau, neurofilament light), now accessible through routine laboratory tests, along with galectin-3 as a tau-clustering, inflammation-linked marker, and a new infusion drug (TB006) targeting that pathway. But can these numbers really be moved in the right direction with targeted lifestyle and medical interventions—and what happens when they are? Enjoy this unusual episode!  And write to us. We read every email. Dawn Lemanne, MD Oregon Integrative Oncology Leave no stone unturned. Deborah Gordon, MD Northwest Wellness and Memory Center Building Healthy Brains
