Recovery often doesn't. In this Season 1 finale, Dr. Leslie Waltke explores why life after cancer may not return to what it once was, why recovery is an active process, and why accepting change should never mean accepting treatable weakness, fatigue, or loss of function. This podcast is brought to you in partnership with CURE. In This Episode 18 • Why the end of treatment is rarely the end of recovery • The myth of closure after cancer • Accepting change without accepting treatable limitations • The role of rehabilitation and exercise • Looking ahead to Season 2 Reflection Questions • What part of your life have you been waiting to restart? • Are there limitations you've assumed were permanent that deserve evaluation? • What is one small step you can take this week toward rebuilding your health, strength, or life?

ep 17 BAD CANCER ADVICE - Why Smart People Fall for Cancer Misinformation

Cancer misinformation is everywhere—social media, influencers, testimonials, miracle cures, supplement stacks, and conspiracy theories. In this episode, Dr. Leslie Waltke explores why misinformation spreads so effectively, why intelligent people are not immune to it, and how patients, caregivers, and healthcare professionals can evaluate claims more thoughtfully. The conversation examines confirmation bias, the appeal of certainty, the power of stories, the influence of social media algorithms, and the importance of balancing hope with evidence. Key Topics Discussed • Why smart people can fall for misinformation • Confirmation bias and uncertainty after a cancer diagnosis • The difference between stories and scientific evidence • How social media amplifies misleading information • Influencers versus expertise • What 'do your own research' really means • How to evaluate health claims online • Trust, skepticism, and expertise in healthcare • Why science changes recommendations over time • The role of identity and community in shaping beliefs • Balancing hope, curiosity, and critical thinking Episode Chapters • 00:00 Introduction – The threat of misinformation • 02:30 Why intelligent people believe false information • 06:00 Confirmation bias and the search for certainty • 09:30 Stories versus scientific evidence • 13:00 Social media and the misinformation machine • 17:30 Influencers, expertise, and visibility • 21:00 'Do Your Own Research' unpacked • 25:00 How to evaluate medical claims • 30:00 Trust, skepticism, and healthcare • 35:00 Why science changes its recommendations • 39:00 Identity, beliefs, and intellectual humility • 43:00 Practical strategies for patients and caregivers • 47:00 Reflection prompts and closing thoughts Reflection Prompts 1. When you encounter health information online, what signals make you trust it? 2. Have you ever changed your mind about an important belief? What helped you do that? 3. How can you balance curiosity, hope, and critical thinking when making healthcare decisions?

ep 16: When Certainty Disappears: Living With Metastatic or Chronic Cancer

A metastatic cancer diagnosis changes more than a treatment plan. It changes a person's relationship with time, uncertainty, planning, and the future itself. In this episode, Dr. Leslie Waltke explores the often misunderstood reality of living with metastatic (stage IV) or chronic cancer. This is not a conversation about giving up. It is a conversation about building a meaningful life when certainty is no longer available. Together, we discuss scan anxiety, the loneliness of looking well, the challenges of making life decisions without clear timelines, the role of exercise and cancer rehabilitation in metastatic disease, and why people living with stage IV cancer deserve to be understood—not stereotyped. This episode is brought to you in partnership with CURE. In This Episode • Why metastatic cancer changes a person's relationship with the future • The psychological burden of living with ongoing uncertainty • Scanxiety and the endless cycle of waiting for results • The loneliness of looking healthy while carrying invisible burdens • The planning paradox: trips, retirement, finances, and major life decisions • Why strength, exercise, and cancer rehabilitation matter in metastatic disease • How uncertainty can clarify values and priorities • Moving forward without toxic positivity Reflection Prompts 1. What decision in your life is uncertainty making difficult right now? 2. What is one thing people misunderstand about living with metastatic disease? 3. What advice would you give to someone newly diagnosed with metastatic cancer?

ep 15 - Can You Trust Your Body Again After Cancer? Why Your Body Is Not Betraying You

Many cancer survivors reach a point where they no longer trust their bodies. Cancer appeared inside the very body that was supposed to protect them. Treatment changed how their body looks, feels, and functions. It is understandable why so many people describe the experience as betrayal. But what if there is another way to understand the story? In Episode 15, Dr. Leslie Waltke explores the idea that a random cellular error should not define your relationship with your body for the rest of your life. Drawing on biology, rehabilitation science, and patient experiences, this conversation reframes survivorship through the lens of partnership rather than resentment. You will learn why the human body is remarkably resilient, how adaptation drives recovery, and why movement, exercise, and rehabilitation are powerful acts of collaboration with your body after cancer. This episode is an invitation to consider a different possibility: your body may not have betrayed you. It may be the same body that has been fighting for you every second of every day. Chapters 00:00 – Opening Hook: Did Your Body Betray You? 01:19 – Welcome & Season One Update 02:35 – What Your Body Was Doing Before Cancer 04:15 – The Biology of Protection and DNA Repair 06:40 – Why 'Betrayal' May Not Be the Right Story 09:20 – The Survivor Who Was Angry at Her Body 12:05 – Resentment vs. Partnership 14:00 – The Science of Resilience and Adaptation 17:10 – Why Cancer Rehabilitation Works 19:15 – Grief, Identity, and Not Recognizing Your Body 22:05 – Movement as Communication 24:40 – A Random Cell Should Not Control the Next 30 Years 27:10 – The Stories We Tell Ourselves 29:30 – Reflection Prompts 31:05 – ABCD Community Shout Out 32:00 – Next Episode: Living With Metastatic Disease Key Topics Discussed • Why many survivors feel their body betrayed them after cancer • The difference between betrayal and biological vulnerability • How the body repairs DNA and protects itself every day • The science of resilience and adaptation • Why rehabilitation works after cancer • Movement as communication and partnership • Grief versus war in the relationship with your body • How the stories we tell ourselves shape recovery • Building a stronger future through partnership rather than resentment Reflection Prompts 1. If you viewed your body as a teammate instead of an enemy, what is one thing you would start doing differently this week? 2. What has your body done for you since your cancer diagnosis that you rarely give it credit for? 3. What story have you been telling yourself about your body since cancer—and is that story helping you build the future you want?

Ep 14 - The Relationship Earthquakes

The Relationship Earthquakes: How Cancer Changes Marriages, Friendships, Families, Intimacy, Parenting, and the Invisible Expectations Between People Cancer does not just change bodies. It changes relationships. In this episode of The After. Cancer Podcast, Dr. Leslie Waltke explores the often-unspoken ways cancer can reshape marriages, friendships, family dynamics, parenting, intimacy, communication, and support systems. While many people expect the physical challenges of cancer, few are prepared for the relationship aftershocks that can continue long after treatment ends. Dr. Waltke discusses why some relationships become stronger while others fracture, how cancer can expose existing patterns within relationships, and why survivors often find themselves carrying not only the weight of their diagnosis but also the emotions and expectations of the people around them. Topics include caregiver dynamics, friendship loss, emotional support, parenting through cancer, body image, intimacy, communication challenges, changing identities, and the difficult reality that cancer sometimes reveals which relationships are capable of growing and which are not. If your relationships changed after cancer—or if you have struggled to explain those changes to others—this episode offers validation, insight, and perspective on one of the most common yet least discussed parts of the cancer experience.
