This looks across many earlier studies rather than running a new one.
This is a review of past studies, not a new treatment you can get.
The short version
This is a review of past research on how food may affect cancer.
What was studied. The authors reviewed studies from 2002 to 2025 found in PubMed, Scopus, and Google Scholar. They looked at diets, nutrients, body weight, gut bacteria, and cancer care.
What they found. Plant-based diets and less red and processed meat were linked to lower cancer risk. Fiber, plant compounds called polyphenols, and omega-3 fats were linked to less cell damage and better immune response. This was seen in several cancers, including glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. Some early data suggest ketogenic diets and fasting may change how tumors use energy.
What this means, and what it doesn't
What it could mean: Good nutrition may support you during cancer care. Talking with a dietitian is low cost and easy to add to regular care. Ask your team what fits your treatment.
What it doesn't mean: This does not mean food can treat a brain tumor. This paper is a summary of other studies, not a new test in people. The authors say large trials are still needed to know if diet changes how long people live. It is not a promise of a cure.
