What does a Cancer Nutritional Therapist with postgrad oncology and Functional and Lifestyle Medicine training actually do?
This week, I’ve been working with a client with bladder cancer who is preparing for major surgery to remove their bladder.
Part of my role right now is helping them prepare their body for what lies ahead. We call this prehabilitation, and what happens before major surgery can be just as important as supporting recovery afterwards.
No 2 people with cancer need the same approach.
Over recent months I’ve worked with people preparing for a mastectomy, and with clients living with stage 4 ovarian, breast and pancreatic cancers, amongst many others.
Different cancers, different treatments, different bodies, and different challenges.
That’s why my work is about far more than just handing somebody a list of foods to eat.
I use a personalised, systems based approach, looking at the whole person and the internal environment in which their health is being supported. We consider nutrition, sleep, physical activity, stress, gut health, social support, medications and treatment, alongside appropriate testing where clinically relevant.
We also consider what scientists call the hallmarks of cancer, the key biological features that enable cancer to develop and progress. This means understanding areas such as altered metabolism, inflammation, immune function and the many signalling processes taking place within the body.
The priorities also change depending on where somebody is in their cancer journey.
This means that before surgery, we may be thinking about nutritional status, protein requirements, muscle mass, lung capacity, and preparing the body for the physical stress of an operation.
During treatment, the priorities can be very different.
After treatment, the conversation changes again towards recovery, metabolic health, modifiable risk factors and helping someone understand what they can do to support their future health.
Another important part of my work is advocacy.
When somebody’s symptoms or clinical history suggest that further investigation may be warranted, I will write to their GP or consultant explaining what I am requesting and, importantly, the clinical rationale for it.
Across 13 years of clinical practice, 100% of the requests I have made for appropriate tests or referrals on behalf of my clients have been accepted, both within oncology and in my wider clinical work.
That wider work has included people living with conditions such as multiple sclerosis, irritable bowel syndrome and ulcerative colitis, amongst many others. Whatever the diagnosis, my approach is always to ask what may be contributing to the symptoms we are seeing, rather than looking at one symptom in isolation.
I hold a BSc in Nutritional Medicine and completed postgraduate training in a systems approach to cancer with a world renowned integrative oncologist, alongside postgraduate training with the Institute for Functional Medicine. I am a Registered Nutritional Therapist with BANT, CNHC Registered, and have been in clinical practice for over 13
I have worked online for 11 of those 13 years, which means I support people throughout the UK and internationally.
