Cancer Survivorship Nutrition

Nutrition After Cancer Treatment

Treatment may have finished, but your health needs haven't.

Nutrition after cancer treatment can help address the physical and metabolic changes that may remain after treatment while supporting your recovery, strength and long-term health.

What happens when cancer treatment finishes?

Finishing treatment is a significant milestone.

But it can also be the point when regular appointments reduce, support becomes less frequent and you're left wondering:

What should I be doing now?

Your body may also be different from before cancer.

You may be dealing with weight changes, loss of muscle, fatigue, menopausal symptoms, digestive changes, altered metabolic health or concerns about bone and cardiovascular health.

And after months of being told what happens next, suddenly much of the responsibility for your health can feel as though it's back in your hands.

Cancer survivorship nutrition is about helping you understand which areas of your health deserve attention now and developing a practical plan for the months and years ahead.

Survivorship is about more than preventing recurrence

Survivorship is about more than preventing recurrence

It's completely understandable that reducing the risk of cancer returning may be front of mind.

But good survivorship care also means looking after the rest of you.

Depending on your individual circumstances, nutrition and lifestyle care after cancer may consider:

Weight & body composition

Weight gain can occur during and after treatment, particularly following treatment for breast and some hormone-sensitive cancers.

The goal isn't simply a lower number on the scales.

Maintaining or rebuilding muscle while improving body composition and metabolic health may be equally important.

Cardiometabolic health

Some cancer treatments and treatment-related weight changes can influence longer-term cardiovascular and metabolic health.

Nutrition can support areas including blood glucose regulation, lipids, blood pressure and overall dietary quality.

Muscle & strength

Cancer treatment, reduced activity, menopause and ageing can all contribute to loss of muscle.

Adequate protein, nutrition and appropriately prescribed exercise are important components of maintaining strength and function.

Bone health

Bone health can become particularly important following menopause and with some cancer treatments, including certain endocrine therapies.

Nutrition assessment may consider protein, calcium, vitamin D and other relevant factors alongside appropriate exercise.

Gut health

Chemotherapy, immunotherapy, radiation, medications, surgery, changes in diet and stress can all affect gastrointestinal health.

Nutrition strategies should be based on your symptoms and individual circumstances rather than automatically prescribing restrictive diets, probiotics or gut supplements.

Menopause & hormonal changes

Cancer treatment can cause or accelerate menopause, while endocrine therapies may create additional symptoms and metabolic changes.

Nutrition and lifestyle strategies can form part of a broader approach to managing these longer-term health considerations.

Weight Gain After Cancer

“I finished treatment, so why have I gained weight”

Weight gain following cancer treatment is common, particularly following breast cancer. It isn't just a matter of willpower.

A combination of factors may contribute, including:

  • treatment-induced menopause

  • endocrine therapy

  • reduced physical activity

  • fatigue

  • changes in muscle mass

  • changes in appetite and eating patterns

  • changes to the gut microbiome

  • sleep disruption

  • stress

  • ageing

  • metabolic changes

This is an area of particular interest in my clinical practice and research.

My Master of Research at Western Sydney University investigated how the Australian healthcare system can better prevent and manage weight gain following breast cancer, including the role of primary care (your GP) in survivorship.

Weight management after cancer therefore needs to consider far more than simply eating fewer calories.

What Should I Eat After Cancer

Moving beyond the search for the perfect anti-cancer diet

After treatment, it's common to start looking for foods, supplements or diets that might help prevent cancer from returning.

Unfortunately, this can quickly lead to restrictive diets and conflicting information.

There is no single food or diet that guarantees cancer will not recur.

Instead, survivorship nutrition focuses on the overall pattern of your diet and lifestyle.

Depending on your circumstances, this may include:

  • eating a predominantly plant-rich diet (Mediterranean Diet)

  • including adequate protein

  • increasing dietary fibre where appropriate

  • including a diverse range of plant foods

  • choosing healthy sources of dietary fat

  • limiting alcohol

  • reducing highly processed foods where appropriate

  • maintaining a healthy body composition

  • supporting regular physical activity

  • addressing relevant nutritional deficiencies

Most importantly, your diet needs to be sustainable. The goal isn't to eat perfectly.

It's to establish an evidence-informed way of eating that supports your health for the long term

Pathology & Long-Term Health

Know what you’re working with

Your post-treatment nutrition plan shouldn't be based on assumptions. Reviewing relevant pathology can help identify areas that may deserve greater attention.

Depending on your medical history and treatment, this may include consideration of:

  • blood glucose and HbA1c

  • insulin where clinically appropriate

  • cholesterol and triglycerides

  • vitamin D

  • iron status

  • vitamin B12 and folate

  • relevant liver and kidney markers

  • other nutritional or metabolic markers where indicated

Where further testing or medical assessment is appropriate, I work collaboratively with your GP or other treating practitioners.

Supplements After Cancer

Do I need supplements after cancer treatment

Possibly, but more isn't necessarily better.

Supplement recommendations should consider your diet, pathology, medications, previous treatment, current health concerns and the evidence supporting their use.

Some people may have a clear nutritional deficiency or increased requirement.

Others may discover they're taking multiple products that duplicate nutrients or have little relevance to their current needs.

My approach is to use supplements strategically when there is a clear clinical rationale, while keeping food and lifestyle as the foundation.

Exercise Belongs In Survivorship Care Too

Nutrition and movement work together

Exercise is one of the most important components of health after cancer treatment.

Where appropriate, I encourage a combination of:

Resistance training
to support muscle, strength, bone health and metabolic health.

Aerobic activity
to support cardiovascular fitness and overall health.

The right exercise program depends on your treatment history, current fitness, symptoms and any physical limitations.

Where appropriate, I may recommend working with an accredited exercise physiologist or physiotherapist with oncology experience.

Cancer survivorship is a major focus of both my clinical practice and research.

My Master of Research examined models of care for preventing and managing weight gain following breast cancer, including how primary care and allied health can better support people after treatment.

My approach brings together nutrition, pathology, body composition, lifestyle, supplements and longer-term health risks to develop recommendations that are practical and individual to you.
