Food and Nutrition Insecurity in Cancer Survivorship: A Global Scoping Review

Area of Science:

• Oncology
• Public Health
• Nutrition Science

Background:

• Cancer survivors and their carers face significant physical, psychosocial, practical, and financial burdens.
• These challenges are compounded by increased nutritional needs during and after cancer treatment.
• Food and nutrition insecurity (FNI) is a growing concern within this population.

Purpose of the Study:

• To systematically map and synthesize the existing literature on FNI among cancer survivors and carers.
• To identify research gaps and inform future research directions.

Main Methods:

• A comprehensive scoping review was conducted, searching six academic databases (APA PsycINFO, CINAHL, Embase, Medline, ProQuest, Web of Science) in July 2025.
• Studies involving adult cancer survivors and/or carers reporting on FNI were included.
• Data were extracted and findings were summarized descriptively by two independent reviewers.

Main Results:

• 135 studies were included, predominantly published recently (88%) and conducted in the United States (81%).
• Most studies focused on cancer survivors (87%), with fewer on carers (14%).
• Population-based studies indicated that an average of 9% of cancer survivors experienced FNI, with 15% at risk. FNI was associated with lower income, younger age, treatment non-adherence, and mortality.

Conclusions:

• FNI is an emerging but under-researched issue in cancer survivorship, particularly affecting carers.
• Future research should prioritize diverse populations, standardized measurement tools, and early, targeted interventions.
• Addressing FNI is crucial for improving cancer survivorship outcomes.
