This episode kicks off Season 5 of the Believe Big podcast, and Ivelisse  welcomes back Dr. Lucas Tims of Root Causes Medical Clinic to untangle the confusing world of cancer testing.

 Dr. Tims unpacks chemosensitivity tests like RGCC and Datar/OncoStat, including real criticisms around consistency and a key blind spot: lab dishes can't recreate the body's tumor microenvironment, so immune-modulating therapies like mistletoe or IV vitamin C can look ineffective even when they're not. 

He explains where these tests still shine, especially for narrowing down later-line chemo or targeted options. He then draws a clear line between monitoring and treatment selection: Signatera tracks ctDNA/MRD after surgery to watch for recurrence, while Tempus profiles tumor genomics to surface druggable targets like PD-L1 for immunotherapy. He also introduces Astron Health as a second-opinion, tumor-board-style review, and Celcuity for pinpointing true driver pathways, with relevance reaching beyond solid tumors into blood cancers. 

Throughout, Dr. Tims returns to one grounding principle: no single test tells the whole story. He encourages listeners to work with their clinicians and pair tumor testing with integrative "terrain" testing, inflammation, immune function, toxins, hormones, gut health, and stress, for the fullest picture of their cancer.

This is our last Summer Replay Episode.  Join Ivelisse as she welcomes Pastors Jason and Lindsay Swain to discuss the transformational power of lament and how it supports healing, resilience, and hope, especially for those facing cancer or loss. 

They share favorite health tips centered on exercise, community, and life-giving hobbies, and explain why Jason paused a church series to teach “The Grace of Lament” after the 20th birthday of their daughter Summer, who died suddenly 20 years ago. 

The Swains describe grief as messy, unpredictable, and a long-term ebb and flow that time may lessen but not heal, emphasizing Jesus as healer and the need for safe guides, counseling, friends, and intentional space to feel. 

They advise others to avoid “Christianese,” not rush grief, show practical help without waiting to be asked, and use lament psalms to bring honest sorrow and hope to God.

 Don’t miss this important episode and take time to make lament part of your faith in healing.

What if everything you thought you knew about cancer diagnosis was wrong? 

Dr. Tom Cowan joins Ivelisse in this Summer Replay episode from 2024 to challenge the conventional story, suggesting cancer isn't a rogue cell gone wild, but the body's clever way of "bagging up" toxins, fear, and old beliefs it hasn't been able to release. 

He walks through how fasting, saunas, mistletoe, and even shifting your thoughts can help your body let go of that load, while pushing back on how much weight we give to screenings and tumor markers. 

It's a conversation that gently asks you to question everything, including the fear that so often drives our choices. Whether or not you agree with every point, it's the kind of perspective-shifting conversation that reminds us how much power we have in our own healing story.

This week we're throwing back to a powerful conversation between Ivelisse and Megan Van Zyl, founder and CEO of Cancer Peace University. 

Megan dives into healing cancer from every angle, physical, emotional, and spiritual, starting with her favorite health tip: connecting lifestyle change to a deeper sense of purpose. She unpacks immune "anergy," chronic infections like H. pylori and hepatitis, toxins, parasites, and the often-overlooked links between thyroid health, mitochondrial function, and oxygen deficiency in cancer. Megan also walks through detox roadblocks like slow methylation, MTHFR issues, lymph stagnation, and liver backup, sharing practical tools like dry brushing, rebounding, coffee enemas, and infrared saunas, plus the role of modified citrus pectin in reducing cancer cell "clumping" around biopsy or surgery.

But the conversation goes beyond the physical. Megan explores psycho-neuroimmunology and how childhood trauma can quietly suppress the immune system's natural killer cells, why talk therapy sometimes isn't enough, and offers gentle tools like free-association journaling and trauma timelines for deeper healing. 

Faith, hope, and stories of spontaneous remission are woven throughout, reflecting the heart of Cancer Peace University's mission. It's an episode full of insight, encouragement, and real hope for anyone walking through a cancer journey.

Ivelisse sits down with her dear friend and integrative oncology expert Dr. Nasha Winters for a conversation that feels as much like a heart-to-heart as it does a masterclass. Together they tackle one of the most confusing and consequential topics in women's health: hormone replacement therapy.

Dr. Winters opens with a simple but powerful daily habit, meeting the sunrise, as an underrated tool for hormonal balance. From there, she unpacks what hormones actually are (messengers, not just chemicals to replenish), traces the eye-opening history of exogenous hormones and their generational effects, and makes a compelling case that most menopausal symptoms are rooted in metabolic imbalance and stress, not deficiency.

She also challenges the assumption that "bio-identical" means safe, offers non-hormonal options for common symptoms, and lays out what a wise, terrain-focused approach to tapering actually looks like.

Warm, honest, and full of practical wisdom — this one is worth sharing with every woman you love.

What does it look like to pray with bold faith when you're facing something bigger than you can handle? In this episode, Ivelisse welcomes Mark Batterson,  lead pastor of National Community Church and bestselling author of The Circle Maker,  for a conversation that will inspire you to keep circling your hardest prayers without letting fear have the final word.

Drawing from the ancient story of Honi, who drew a circle in the sand and prayed boldly for rain, Mark shares what it means to bring God audacious, persistent prayers, especially in the face of illness. He opens up about his own healing from 40 years of asthma, his wife Lora's breast cancer journey, and how "circling your Jericho" can transform the way you face a diagnosis. You'll also hear how mindset, laughter, gratitude, nutrition, and community are all part of participating in your healing, and how to tune into the Holy Spirit's voice through Scripture, silence, and wise counsel.

Whether you're in the middle of a health battle or walking alongside someone who is, this episode will remind you that God's dreams for your life are worth the wait, and worth the prayer.

Why does cancer so often come back, even after treatment appears successful? In this episode of the Believe Big Podcast, Ivelisse sits down with renowned naturopathic doctor Dr. Michael Karlfeldt to uncover the hidden root causes behind cancer recurrence and what patients can do to support true healing beyond tumor shrinkage.

Dr. Karlfeldt explains how chronic infections, environmental toxins, stress, unresolved trauma, and weakened immunity can create the perfect “terrain” for cancer to return, even years later. He also shares why conventional treatments alone may not be enough, how cancer stem cells can remain dormant, and the integrative strategies he’s seen help patients rebuild their health and resilience.

From mistletoe therapy and IV vitamin C to detoxification, immune restoration, functional testing, gratitude practices, nutrition, spiritual connection, and reducing toxic exposures, this conversation offers practical and hopeful insights for anyone navigating cancer, recovery, or prevention.

Whether you’re a patient, survivor, caregiver, or simply passionate about changing the future of cancer care, this episode will challenge the way you think about healing and inspire you to share it with someone who needs hope today.

Award-winning filmmaker Jacob Williams joins Ivelisse in this episode to share the powerful and deeply personal story behind his prostate cancer diagnosis, and the path that led him far beyond the standard “surgery or radiation” conversation. 

Faced with rising PSA levels, multiple biopsies, and limited options, Jacob sought out four second opinions and ultimately chose an integrative approach that combined nutrition, exercise, and therapies like mistletoe and hyperthermia. In this episode, he opens up about why so many men avoid talking about prostate health, and how breaking that silence could save lives. Jacob walks listeners through the turning points in his healing journey, including the treatments that helped reduce lesions and lead to no evidence of disease. 

If you or someone you love is navigating cancer, this conversation will challenge what you think you know and inspire you to explore every option with confidence and hope.
