Breast Cancer Services
At Mosaic Medical, we provide personalised integrative support for women at every stage of the breast cancer journey — from reducing risk and navigating treatment to living well with metastatic disease.
Our approach combines conventional medical understanding with evidence-informed nutrition, lifestyle medicine and advanced functional testing to support the whole person, not just the diagnosis.
Mosaic Medical offers an integrative breast cancer support service combining conventional medical understanding with evidence-informed nutrition, lifestyle medicine and functional testing — for women reducing their risk, going through treatment, or living with metastatic disease. Care is led by Dr Amy Walker, a former NHS consultant trained in integrative oncology following her own breast cancer diagnosis, working alongside nutritional therapist Jessica Fonteneau, and designed to complement your existing oncology care rather than replace it.

Reduce Your Risk of Breast Cancer or Recurrence
Whether you have a strong family history, dense breasts, previous breast cancer, or simply want to take a more proactive approach to your health, we help you understand the factors that may influence breast cancer risk.
There is now growing evidence that metabolic health, inflammation, hormone balance, sleep, nutrition, movement and environmental exposures all play a role in breast cancer development and recurrence risk.
Our role is to help you focus on the areas that genuinely matter — without overwhelm, fear or unnecessary intervention.
Support may include:
- Personalised nutrition and metabolic health support
- Blood sugar and insulin optimisation
- Hormone and menopause support
- Weight, exercise and body composition strategies
- Sleep and circadian health
- Stress and nervous system support
- Functional and genomic testing where appropriate
- Have a strong family history of breast cancer
- Have previously had breast cancer
- Feel anxious about their future risk
- Want a more personalised understanding of their health
- Are looking for evidence-informed lifestyle guidance
Support During Breast Cancer Treatment
A breast cancer diagnosis can feel overwhelming. Many women are looking for safe, evidence-informed ways to support their bodies alongside surgery, chemotherapy, radiotherapy, endocrine therapy or immunotherapy.
At Mosaic Medical, we work alongside your oncology team to help support patients through conventional treatment while also supporting resilience, recovery and quality of life
Our integrative approach is designed to complement — not replace — conventional cancer care.
We may support you with:
- Nutrition during chemotherapy and radiotherapy
- Fatigue and energy support
- Gut health and digestive symptoms
- Sleep, anxiety and nervous system regulation
- Exercise and muscle preservation
- Bone, heart and metabolic health
- Managing treatment side effects
- Personalised supplement guidance
- Fasting-mimicking protocols where appropriate
Support for Metastatic Breast Cancer
Living with metastatic breast cancer brings unique physical and emotional challenges. Many women are looking for ways to feel more supported, more informed and more empowered in day-to-day life.
Our approach focuses on helping you optimise quality of life, resilience and overall wellbeing alongside your oncology treatment.
We understand that this journey is deeply individual. Some patients want help navigating nutrition and side effects. Others are seeking support with fatigue, anxiety, sleep, treatment tolerance, or maintaining strength, independence and quality of life.
Support may include:
- Personalised nutrition during ongoing treatment
- Support for fatigue and energy
- Nervous system and emotional well-being support
- Digestive and metabolic health
- Sleep and circadian rhythm support
- Exercise and movement guidance
- Advanced functional testing where appropriate
- Collaborative integrative support alongside oncology care

Meet Your Team
Your care is led by Dr Amy Walker, who combines her background as a former NHS consultant with additional training in functional medicine and integrative oncology following her own breast cancer diagnosis.
The Breast Cancer Service was created from a desire to offer patients the kind of care many women feel is missing — time, personalised support, and a space to explore the wider factors influencing health and wellbeing alongside conventional cancer treatment.
Nutritional therapy is an integral part of the Breast Cancer Service. Jessica Fonteneau works closely alongside Dr Walker to provide evidence-informed nutritional and lifestyle support for patients at all stages of the breast cancer journey.
Together, Dr Walker and Jessica provide an integrated and highly personalised approach, combining medical, nutritional and lifestyle support tailored to each individual.
Nutritional Therapy Support
- Blood sugar and metabolic health
- Treatment-related symptoms
- Digestive and gut health
- Weight and body composition
- Fatigue and recovery
- Fasting-mimicking protocols where appropriate
- Confidence around food after diagnosis
Advanced Testing
Sometimes standard medical testing does not tell the whole story.
Where appropriate, we may use advanced functional and genomic testing to gain a deeper understanding of factors such as hormone balance, metabolic health, inflammation, gut health and detoxification pathways.
This may include:
- Comprehensive blood testing
- Lifecode Gx® nutrigenomics
- DUTCH hormone testing
- Microbiome testing
- Datar chemosensitivity testin
Not everyone needs extensive testing. For many women, focusing on nutrition, sleep, movement, stress and metabolic health is the most important starting point.
How This Approach Differs
- We look at the whole person
- Not just the diagnosis, but the factors influencing your overall health and wellbeing.
- We work alongside conventional care
- Our approach is supportive and integrative, never alternative.
- We personalise care
- Recommendations are tailored to your biology, symptoms, treatment and goals.
- We focus on realistic change
- Small, sustainable changes often matter more than perfection.

Frequently Asked Questions
Will this replace my oncology care?
No. Everything we offer is designed to work alongside your oncology team, not instead of it — we focus on the nutrition, lifestyle and wellbeing factors that sit outside a standard treatment plan.
I haven't been diagnosed — can you still help me reduce my risk?
Yes. Risk reduction is one of the three main pathways we support, alongside active treatment and living with metastatic disease.
What if I'm living with metastatic breast cancer?
We have a dedicated pathway for ongoing support at this stage, focused on quality of life, symptom management and realistic, sustainable changes rather than overwhelming you with information.
Who will I actually be working with?
Your care is led by Dr Amy Walker, supported by nutritional therapist Jessica Fonteneau — together they provide integrated medical, nutritional and lifestyle support tailored to you.
What does it cost, and is it covered by insurance?
Current pricing is on our pricing page at mosaic-medical.com/pricing. A free discovery call is the easiest way to talk through your situation and what’s included before booking.
