A new research review published in the Journal of Clinical Medicine suggests precision nutrition — dietary strategies tailored to a person’s genes, metabolism, microbiome and lifestyle — could one day play a role in preventing and treating bladder cancer.
Rather than relying on one-size-fits-all dietary advice, precision nutrition aims to use biological data to guide individualized recommendations. The paper explores how advances in genomics, metabolomics and microbiome science are opening the door to personalized dietary interventions that might influence cancer risk, progression and response to treatment.
The authors pointed to several areas of promising research. For example, dietary patterns and nutrients may interact with tumor biology, inflammation and metabolic pathways that influence bladder cancer development.
Biomarkers such as genetic variants, metabolic profiles and microbiome compositions could help identify individuals who might benefit from specific nutritional interventions or lifestyle changes.
In particular, the role of the urinary and gut microbiome is becoming an important area of focus in bladder cancer research. Differences in microbial composition have been linked to cancer development and treatment response, suggesting that diet-driven changes in the microbiome could influence future therapies.

However, the review emphasizes that translating precision nutrition from theory into clinical practice has many challenges. Scientific barriers include the complexity of integrating multiple “omics” datasets, variability between individuals and the lack of standardized methods. Broader obstacles, including cost and equitable access, also limit widespread implementation of personalized dietary approaches.
Additionally, most existing studies are observational or preclinical, making it difficult to prove that personalized nutrition strategies directly improve bladder cancer outcomes. The researchers say more large-scale clinical trials are needed before precision nutrition can be reliably incorporated into cancer care.
Despite these challenges, the authors argue that precision nutrition represents a promising frontier in oncology. By combining dietary science with molecular data, future approaches could complement existing treatments and support more individualized prevention and care.
“This type of precision guidance for individuals with BC should be accessible to everyone without being excessively expensive,” the study’s authors concluded. “The successful implementation of such an inclusive approach could significantly improve the nutritional status of a significant number of individuals with BC and potentially have a significant public health impact.”
