London, January 2026 — Dr Andy Gaya was interviewed recently by The Telegraph for an in-depth feature exploring the alarming rise of bowel cancer in younger adults and the practical lifestyle changes that can help reduce risk. You can read the original article here:
As one of the UK’s leading GI cancer specialists, Dr Gaya remains at the forefront of clinical research. He is recognised nationally for his expertise in gastrointestinal (GI) cancers and widely respected for championing a holistic approach to cancer care. As such Dr Gaya was invited by the newspaper to share his views and advice to readers.
A concerning trend
In the interview, Dr Gaya highlighted a pattern he has been observing: bowel cancer diagnoses are climbing sharply in people under 50. While incidence in older adults has remained relatively stable, younger generations are experiencing a significant rise (with some patients now presenting in their teens). This pattern is reflected in the latest bowel cancer data and research.
Although the exact cause remains unclear, Dr Gaya emphasised that genetics alone cannot explain such a rapid shift. Instead, he pointed to environmental and lifestyle factors that have changed dramatically over recent decades.
UPFs and microplastics
Dr Gaya discussed emerging evidence linking ultra-processed foods and microplastic exposure to inflammation and potential cancer risk. While research is ongoing, he noted that these modern exposures are among the most plausible contributors to the rise in early-onset bowel cancer.
He explained that although individuals cannot easily avoid microplastics, they can make meaningful changes to their diet. Reducing reliance on ready meals, increasing fibre intake, and choosing minimally processed foods are all practical steps that support gut health and reduce inflammation.
Simple, everyday diet swaps
During the interview, Dr Gaya outlined several achievable dietary adjustments that can help lower bowel cancer risk at any age. These include:
- Favouring home-cooked meals over ultra-processed options
- Choosing wholemeal bread instead of white
- Replacing red and processed meats with lean poultry (or plant-based alternatives)
- Opting for probiotic-rich foods such as kefir to support the gut microbiome
- Moderating alcohol intake or choosing alcohol-free drinks

A holistic approach
Dr Gaya also highlighted the growing evidence that moderate, regular exercise has a measurable impact on cancer outcomes. He referenced recent high-quality research showing that even brisk walking several times a week can strengthen the immune system and improve survival in patients recovering from colon cancer treatment.
Known for integrating lifestyle, nutrition, and wellbeing into his clinical practice, Dr Gaya used the interview to reinforce the importance of viewing cancer risk through a broad lens. While no single factor determines whether someone will develop bowel cancer, he stressed that small, sustainable changes can collectively make a meaningful difference.
“Cancer prevention isn’t about perfection. It’s about creating an environment in the body where inflammation is lower, the immune system is stronger, and harmful exposures are minimised.”

One of the UK’s most trusted oncologists
Dr Gaya’s contribution to The Telegraph reflects his ongoing commitment to public awareness and education on GI cancer. As research evolves, Dr Gaya continues to share accessible, practical guidance to empower cancer patients to take control of their health after diagnosis.
