Emerging research and clinical experience are increasingly highlighting a crucial, yet often overlooked, component of cancer care: the powerful impact of diet and physical activity. Far from being mere supplementary measures, nutrition and movement are gaining recognition for their vital roles in cancer prevention, treatment efficacy, managing side effects, and ultimately, improving long-term survival and quality of life.
This critical topic was recently the focus of a significant event co-organized by the National Institute for Health and Care Research (NIHR) Cancer and Nutrition Collaboration and the World Cancer Research Fund (WCRF). Nutritional scientist and integrative health practitioner, Toral Shah, shared key takeaways from this important gathering, which brought together experts to discuss how best to integrate nutrition and physical activity guidance into standard oncology care for both clinicians and patients.
The Compelling Evidence: How lifestyle Shapes Cancer Outcomes
The conversation at the NIHR and WCRF event underscored the mounting evidence linking lifestyle factors to cancer. Rachael Gormley, CEO of the WCRF, presented a striking perspective: challenging the common perception that cancer is solely a genetic lottery, she suggested that potentially up to 50% of cancer cases might be preventable through strategic nutrition and lifestyle choices. This figure alone emphasizes the immense public health potential of focusing on modifiable factors.
But the influence of diet and exercise doesn’t stop at prevention. For individuals diagnosed with cancer, lifestyle interventions play a pivotal role in the journey after diagnosis.
Beyond Prevention: Enhancing Survival and Quality of Life
Physical activity, often counterintuitively minimized during treatment with advice focused primarily on rest, has demonstrated significant benefits for cancer patients. Evidence suggests that engaging in appropriate exercise can help reduce the severity and duration of treatment-related side effects, such as fatigue, nausea, and neuropathy.
Moreover, physical activity is linked to improved long-term prognoses. Professor Vicky Coyle was cited at the event for her involvement in trials like the CHALLENGE trial, which provides compelling evidence that physical activity can substantially reduce the risk of cancer recurrence and mortality in patients. This highlights a clear discrepancy between current common practice (advising rest) and the robust scientific evidence supporting movement.
Similarly, nutrition plays a fundamental role in supporting patients through treatment, maintaining strength, managing weight changes, and reducing the risk of treatment interruptions. Adopting dietary patterns rich in plant-based foods and fiber, for instance, is supported by evidence for both cancer prevention and better health outcomes post-diagnosis.
Addressing the Knowledge Gap in Clinical Oncology
Despite the growing body of evidence, a significant barrier remains in integrating this knowledge into routine clinical practice. Many oncology professionals, while adept at managing complex medical treatments, report lacking confidence and adequate training in providing specific, actionable advice on nutrition and physical activity to their patients.
Professor Steve Wootton from NIHR highlighted the urgent necessity of educating healthcare professionals on this topic. He pointed out the critical need to embed comprehensive cancer nutrition and lifestyle content directly into medical school curriculums. Promisingly, Universities like Lincoln and Southampton are recognized as pioneers currently integrating these vital subjects into their medical training programs.
The current gap often leads to generic advice or, as mentioned, recommendations for rest rather than tailored physical activity plans. Dr. Lucy Gossage further stressed the crucial need for established referral options – clear pathways for patients seeking specialized support from dietitians, exercise physiologists, or other experts who can provide personalized guidance based on their specific cancer type, treatment plan, and overall health status.
Shifting the Paradigm: Towards Integrative Cancer Care
The discussions at the NIHR and WCRF event revealed a collective call for a fundamental shift in the approach to cancer treatment. The traditional focus on pharmacological interventions as the sole solution is broadening to recognize the power of supportive and integrative therapies.
This shift requires investing in Continuing Professional Development (CPD) training for clinicians to enhance their knowledge and confidence in discussing lifestyle factors. It also necessitates greater availability of reliable resources for both patients and healthcare providers, along with enhanced partnerships between different sectors – healthcare, research institutions, and patient advocacy groups.
The ultimate goal is to support “thrivership” – a concept that moves beyond simply surviving cancer to living well after diagnosis and treatment. This aligns strongly with the principles of integrative or supportive oncology, which seeks to combine conventional treatments with evidence-informed complementary therapies and lifestyle modifications to improve overall patient well-being and outcomes. Professor Steve Wootton concluded that implementing effective change must remain patient-focused, acknowledging potential systemic inertia, particularly within large healthcare systems like the NHS in the UK.
A Personal Testament to Lifestyle’s Power
The importance of this topic holds deep personal significance for Toral Shah, who shared insights from the event. Her passion originated over 25 years ago when her mother received no nutrition or lifestyle advice following breast cancer treatment. This personal experience illuminated a critical void in patient care.
As a three-time breast cancer survivor herself, Shah attributes her own survival journey significantly to her commitment to diet and physical activity. This powerful personal testimony fuels her dedication to researching and disseminating knowledge about the role of lifestyle in oncology. She expressed enthusiasm and optimism at seeing the narrative finally gaining traction within mainstream oncology discussions, moving towards a more holistic understanding of cancer care.
The Path Forward: Implementing Change and Empowering Patients
Integrating diet and exercise effectively into cancer care requires a multi-pronged approach. It involves systemic changes in medical education and professional training, developing clear referral pathways, creating accessible and reliable resources, and fostering a culture where lifestyle discussions are a routine part of patient consultations.
Overcoming the challenges of limited professional confidence and outdated advice is paramount. Empowering both clinicians with knowledge and patients with actionable strategies is key to realizing the full potential of lifestyle interventions in improving cancer outcomes and supporting long-term thrivership. The growing collaboration between organizations like NIHR and WCRF, highlighted by events like this one, signals a promising direction towards a future where diet and exercise are recognized and utilized as fundamental pillars of comprehensive cancer care.
Frequently Asked Questions
What role do diet and exercise play in cancer care?
Diet and exercise are increasingly recognized as essential components of cancer care, impacting outcomes at multiple stages. They are crucial for cancer prevention, with lifestyle changes potentially preventing up to 50% of cases. For those diagnosed, evidence shows physical activity can reduce treatment side effects like fatigue and improve survival rates by lowering recurrence risk. Nutrition supports overall health during treatment and contributes to long-term well-being.
Where are medical schools starting to teach cancer nutrition?
While historically underrepresented, cancer nutrition and lifestyle content are beginning to be integrated into medical school curriculums. Specific institutions like Lincoln and Southampton Universities in the UK were mentioned at the event as leading efforts in this area. Experts advocate for this integration to become standard across all medical training programs to better equip future healthcare professionals.
Should cancer patients focus on rest or physical activity?
Contrary to outdated advice often focused solely on rest, current evidence strongly supports the benefits of physical activity for cancer patients. Appropriate exercise can help manage treatment side effects and has been shown to reduce the risk of recurrence and mortality. While rest is important for recovery, tailored physical activity programs are a vital part of modern cancer care and should be discussed with healthcare providers.
