Nursing Care to Reduce Suicide Risk in Cancer Patients: A Narrative Review of the Literature

Background: Cancer is one of the leading causes of morbidity and mortality worldwide and in Spain. Individuals with cancer are at a higher risk of suicide compared to the general population due to both general and disease-specific risk factors. Objective: To update knowledge on nursing care measures to address the risk of suicide in cancer patients. Methods: A narrative review was conducted by searching PubMed, WOS, Scopus, and CINAHL during February and March 2025. The inclusion criteria comprised original qualitative, quantitative, and/or mixed-methods studies related to the topic of the review. Results: Of the 289 identified studies, 23 were selected. Twelve studies of cancer patients, ten studies of healthcare professionals, and one study of caregivers and survivors were included. Regarding suicide risk factors, eight studies addressed demographic aspects, fifteen socio-economic factors, twenty-one psycho-emotional factors, and seventeen physical factors. Key risk factors included male sex, advanced age, social isolation, lack of social support, hopelessness, and physical deterioration. Seventeen studies highlighted the need for continuous and comprehensive nursing care using validated tools for systematic assessment of suicide risk. Eight emphasised the importance of ongoing training in suicide prevention, which is essential for developing communication skills and improving therapeutic relationships. Five studies underscored the relevance of a holistic approach that addresses the physical, emotional, social, and spiritual dimensions of patient care. Six extended this approach to include family members and caregivers. Conclusions: Suicide risk in cancer patients is associated with multiple risk factors. Emotional support and a comprehensive, continuous nursing approach-based on systematic assessments, specialised training, and a holistic focus-are key to effective suicide prevention.
