Purpose: Lynch Syndrome is an inherited condition associated with increased lifetime risks of colorectal, upper gastrointestinal, endometrial, ovarian, and prostate cancers. While diet and lifestyle recommendations exist to help reduce cancer risk, limited research explores how individuals with Lynch Syndrome receive and implement this advice. This study investigated opinions and attitudes towards nutritional guidance.

Method: Eighteen participants diagnosed with Lynch Syndrome were recruited via the Lynch Syndrome UK Facebook page. In-depth, semi-structured virtual interviews were conducted, and transcripts were analysed using thematic analysis.

Results: Two major themes emerged: Trust and Barriers. Subthemes under Trust included Frustration, Knowledge and Understanding, and Journey to Balance. Barriers included Finance, Time and Convenience, and Willpower. Participants expressed frustration over the lack of trustworthy, specialist nutritional guidance. There was a desire for more personalised support and education tailored to Lynch Syndrome, particularly for managing symptoms like early menopause following risk-reducing surgery. Dietary adherence was influenced by factors such as nutritional knowledge, perceived cancer risk, and quality of life.
