Supporting patients undergoing genomic testing for Lynch syndrome as part of their diagnostic cancer pathway

Knowledge of genomics and genetic testing is increasingly being used to inform cancer diagnosis, prognosis and effective treatment, known as personalised or precision medicine. The NHS aims to embed genomics into diagnostic pathways, meaning that it is becoming a routine aspect of cancer care. Therefore, it is important that cancer nurses have an understanding of genomics and personalised medicine so that they can provide appropriate information and support to patients and families. This article is designed to equip nurses with the skills to start essential genomic conversations with patients to support them through their cancer pathways. It focuses on Lynch syndrome, an inherited condition that increases the risk of developing certain cancers, and explains the genetics, testing, surveillance and psychological aspects of care for patients and families affected by this syndrome.
