Functional Nurse Academy Success Story: Amber Andrasek and Terrain-Focused Oncology Support

Jul 31 / Melissa Schreibfeder, BSN, RN, BC-FMP

🎧 Listen to my podcast with Amber below!

Some of the most meaningful nursing specialties are born from the experiences that transform us personally.
On this episode of the Functional Nurse Academy Podcast, I had the opportunity to interview Amber Andrasek, RN, BA Psych, BC-FMP, founder of Redeeming Hope and Wellness.

Amber is a registered nurse, board-certified functional medicine practitioner, and metabolic terrain-focused health consultant who helps women better understand the underlying factors that may be placing stress on their health.
Her work is deeply personal.
Before launching her functional nursing practice, Amber navigated years of chronic fatigue, Lyme disease, mold-related illness, and eventually stage 3C inflammatory breast cancer. Her experience led her to combine conventional cancer treatment with a personalized metabolic and terrain-focused approach designed to support her body throughout treatment and beyond.
Today, Amber is approaching three years with no evidence of disease and uses what she learned through her own health journey and Functional Nurse Academy training to support women facing cancer, autoimmune concerns, chronic fatigue, metabolic dysfunction, and other complex health challenges.

What Amber Loved About Functional Nurse Academy

Amber credits Functional Nurse Academy with helping her develop the clinical knowledge, practical tools, and confidence needed to launch her own functional nursing business.

Even after completing the core program, she continues returning to the course materials and mentorship library when working through complex client cases.

Thank you Melissa for such a comprehensive program to help Nurses get educated in the world of Functional Medicine. Your educational approach was clear and methodical and you provided so many tips and tricks to getting a practice set up! You really hold our hands through setting up a practice and this is deeply appreciated and makes it far less intimidating.

The "done for you" resources and practitioner toolkit are just AMAZING and save so much time! Thank you for being a trailblazer and encouraging other Nurses to join this movement that we might make a real impact on shifting Chronic Health issues in this country. In helping others to get well, it allows them to live out the calling God has on their lives! That is what makes this work deeply meaningful to me!!!

Comprehensive Root-Cause Education

FNA helped Amber better understand the functional patterns behind immune dysregulation, autoimmunity, gut dysfunction, hormone imbalance, environmental illness, and chronic symptoms.

Functional Laboratory Training

She learned how functional tests such as the GI-MAP and DUTCH test may provide additional insight into digestion, microbiome health, hormone metabolism, stress response, and other patterns that can influence overall wellness.

Ongoing Mentorship and Clinical Support

Amber values having access to the FNA Monthly Mentorship and its extensive library of clinical and business deep-dive topics. When she encounters a challenging client concern, she can revisit relevant modules, refresh her knowledge, and continue learning.

Education That Continues After Graduation

Functional medicine is always evolving, and Amber appreciates that FNA continues creating new educational content. She described the program as a trusted resource that still supports her practice years after she initially enrolled.

A Supportive Functional Nursing Community

Rather than trying to navigate complex cases and business ownership alone, Amber has access to an experienced community of functional nurses and practitioners.

Amber now regularly recommends Functional Nurse Academy to nurses interested in comprehensive functional medicine education and building an independent wellness practice.

Amber’s Inflammatory Breast Cancer Story

Amber was 42 years old and had a young child when she was diagnosed with stage 3C inflammatory breast cancer. Inflammatory breast cancer is a rare, aggressive form of breast cancer that can progress quickly and is typically diagnosed at a more advanced stage.

Amber’s diagnosis and treatment journey ultimately became a major turning point in both her personal health and her nursing career.

Combining Conventional and Integrative Cancer Support

Amber’s treatment journey included nearly every major conventional cancer intervention available to her. She underwent:

  • An intensive chemotherapy regimen
  • Twice-daily radiation
  • Multiple surgeries
  • Ongoing oncology care
  • Pharmaceutical treatment intended to reduce recurrence risk


Before beginning conventional treatment, Amber spent several months at a holistic cancer clinic in Arizona. While there, she received a variety of intravenous and supportive therapies.

However, the cancer continued to progress. That experience taught Amber an important lesson: cancer support does not always have to be approached as an either-or decision between conventional medicine and integrative care.

After returning home, she met with a breast cancer specialist who helped develop her chemotherapy plan. At the same time, Amber began working with a physician trained in the metabolic approach to cancer. She chose to complete conventional treatment while also incorporating individualized metabolic and terrain-focused strategies alongside it.

This collaborative approach became central to both her recovery and the work she now does with clients.

What Is a Metabolic Terrain-Focused Approach?

A terrain-focused approach considers more than the tumor or diagnosis alone. Amber describes the body’s terrain as its internal ecosystem.

She compares it to a garden. When the soil is balanced, nutrient-rich, and properly supported, the garden is better equipped to flourish. But when the soil becomes depleted, inflamed, toxic, or dysregulated, unwanted weeds may be more likely to grow. In the body, the terrain may be influenced by areas such as:

  • Metabolic health  
  • Blood sugar regulation  
  • Mitochondrial function  
  • Nutritional status  
  • Immune regulation  
  • Environmental exposures  
  • Gut and microbiome health  
  • Genetics and epigenetics  
  • Hormone metabolism  
  • Nervous system regulation  
  • Chronic stress and trauma  
  • Emotional well-being

Rather than assuming one factor caused a complex illness, Amber looks at the patterns that may be placing the greatest burden on an individual’s system. Her goal is to help clients better understand those patterns and develop a personalized plan to support resilience, overall wellness, and collaboration with their medical team.

Mistletoe Therapy, Fasting, and Therapeutic Nutrition

During treatment, Amber incorporated several individualized strategies under the guidance of her practitioners.
One of those interventions was mistletoe therapy.

Mistletoe is used more commonly in some European integrative oncology settings. Amber received a specific form of mistletoe selected according to her individual health history and cancer process.

She also incorporated fasting around chemotherapy. Her plan generally involved fasting the day before treatment, during treatment, and for part of the day afterward.

Between chemotherapy sessions, she followed a carefully monitored therapeutic ketogenic diet based on whole foods. She tracked both blood glucose and ketones and used targeted nutraceuticals selected according to her laboratory data and genetic findings.

Amber emphasized that these interventions were not chosen from a generic online cancer protocol.
They were personalized based on her specific terrain, genetics, laboratory data, treatment plan, and medical needs.

She believes these additional supports helped her tolerate an exceptionally difficult treatment regimen, although she is also careful to acknowledge the importance of her conventional oncology care and surgical team.

Looking Beyond the Tumor

One of the central themes of Amber’s story is that treating cancer and rebuilding health are not always the same process. Conventional oncology appropriately focuses on removing or destroying cancer cells through treatments such as surgery, chemotherapy, radiation, and pharmaceutical therapy.
But Amber believes another question also deserves attention: What was happening within the body that may have allowed the disease process to develop or progress?

Before her cancer diagnosis, Amber had struggled with chronic fatigue, Lyme disease, mold exposure, and immune dysregulation. From a terrain-focused perspective, these factors may place additional stress on the immune system and the body’s ability to maintain balance. Her work now includes helping clients examine potential contributors such as:

  • Mold and environmental exposures  
  • Heavy metal burden  
  • Gut imbalances  
  • Nutrient depletion  
  • Blood sugar dysregulation  
  • Chronic infections  
  • Hormone metabolism  
  • Genetic vulnerabilities  
  • Emotional trauma  
  • Persistent nervous system stress

This does not mean that any single factor caused a person’s illness. Instead, Amber looks at how multiple burdens may interact and contribute to the overall health picture.

Genetics, Epigenetics, and Personalized Support

Amber also uses genetic and epigenetic information to help personalize her clients’ wellness plans.
Two people may live in the same environment and respond very differently.

Amber shared that she and her husband lived in the same home, yet she became significantly affected by mold while he did not. Through further investigation, she learned that she had multiple genetic variants that may influence how effectively her body processes and eliminates certain substances. In her practice, Amber may consider patterns related to:

  • Detoxification capacity  
  • Estrogen metabolism  
  • Vitamin D utilization  
  • Fatty acid metabolism  
  • Nutrient handling  
  • Blood sugar regulation  
  • Insulin resistance risk

This information helps her create what she describes as a personalized roadmap for the client. Rather than providing everyone with the same nutrition, supplement, or lifestyle plan, she uses health history, symptoms, laboratory findings, genetics, and individual circumstances to determine where support may be most helpful.

The Role of Stress, Trauma, and Emotional Health

Amber’s work also acknowledges that physical health cannot always be separated from emotional and nervous system health. Chronic stress and unresolved trauma can influence sleep, digestion, stress hormones, immune function, daily habits, and the body’s overall capacity to recover.

One of Amber’s clients had already reached no evidence of disease after breast cancer treatment when she began working with her. However, the client had not yet addressed many of the foundational or emotional factors that were continuing to affect her health.

The client had experienced significant trauma and an abusive marriage. As part of her terrain-focused wellness work, Amber helped her address nutrition, metabolic health, lifestyle habits, stress patterns, and emotional burdens. Amber believes this whole-person approach is especially important because clients are not simply a diagnosis, laboratory result, or collection of physical symptoms.

Their experiences, relationships, thoughts, environments, and emotional well-being all contribute to the broader health picture.

Client Success Stories from Redeeming Hope and Wellness

During our conversation, Amber shared several examples of clients she has supported through her practice. 

One client had already completed breast cancer treatment and reached no evidence of disease. Amber helped her begin rebuilding her terrain by reviewing health data, genetics, nutrition, metabolic patterns, lifestyle factors, and emotional stress.

Another client in her 50s came to Amber struggling with low energy and persistent symptoms that had not been fully resolved.

Through functional testing, including a GI-MAP and DUTCH hormone testing, Amber identified several areas that warranted additional support, including an H. pylori pattern, gut health concerns, stress response issues, and foundational lifestyle factors.

After working together, the client told Amber she had not felt that good since her 30s. For Amber, stories like these are a reminder of why she became a nurse in the first place: to help people feel better, understand their bodies, and move forward with greater hope and direction.

Turning Suffering Into Purpose

Amber’s story is a powerful example of how a painful health experience can transform the direction of a nursing career. She endured chronic illness, an aggressive cancer diagnosis, demanding treatment, and years of uncertainty.

But on the other side of that experience, she found a deeper calling. Today, she uses her nursing background, functional medicine education, personal experience, and terrain-focused training to help other women better understand their bodies and feel more empowered in their health journeys.

Her role is not to replace oncology care or direct medical treatment. It is to provide education, coaching, functional wellness guidance, and collaborative support so clients can examine the whole picture and build a stronger foundation for long-term health. Amber’s journey reminds us that functional nurses can use their clinical experience far beyond the conventional setting.

With the right education and support, nurses can build meaningful practices, develop specialized areas of expertise, and serve clients in ways that honor the complexity of the whole person.

Frequently Asked Questions About Becoming a Functional Nurse

What is a functional nurse?

A functional nurse is a licensed nurse who applies the principles of functional medicine to educate and empower clients by helping them identify and address potential root causes of health concerns. Functional nurses focus on nutrition, lifestyle, sleep, stress management, environmental influences, and other evidence-informed approaches while practicing within their nursing scope of practice.

What is the difference between a functional practice owned by a NP and RN or LPN?

Nurse practitioners may operate a medical practice where permitted by state law. Depending on their state's regulations, NPs may diagnose medical conditions, order and interpret laboratory testing, prescribe medications, and provide medical treatment.

RNs and LPNs can own and operate independent wellness-focused functional nursing practices. Rather than diagnosing or treating medical conditions, they educate and empower clients through personalized wellness plans, nutrition and lifestyle education, health coaching, specialty laboratory education and on going support.

How Do Non-Advanced Practice Functional Nurses Utilize Laboratory Testing?

RNs and LPNs can access both conventional and specialty laboratory testing through partnerships with functional medicine laboratories. These partnerships allow nurses to order testing through a physician network at affordable wholesale pricing, while practicing within their professional scope.

While nurse practitioners (NPs) may have the authority to diagnose medical conditions and independently order laboratory testing depending on their state laws, non-advanced practice nurses use laboratory data to educate clients about potential patterns of dysfunction. Laboratory findings can also help guide personalized wellness recommendations and support collaboration with the client's healthcare team to optimize health outcomes.

Please note: Certain states, including New Jersey (NJ) and Rhode Island (RI), have restrictions on laboratory ordering through some functional medicine laboratory networks.

Does Functional Nurse Academy provide continuing education for nurses?
