Abstract
BACKGROUND: Men with breast cancer experience unique physical and emotional challenges. However, a thorough understanding of these experiences including the psychosocial effects and supportive care needs have received less attention. In some settings, men with breast cancer experience stigma within the healthcare system and their care needs are not prioritised. This influences the level of professional support offered, consequently worsening their health and well-being outcomes. This review explored the variabilities in the experiences and treatment modalities of male breast cancer (MBC) across different contexts. METHODS: All primary study designs including qualitative, quantitative, and mixed methods studies that reported on the experiences, treatment approaches and outcomes of MBC were included in this systematic review. Six databases (Embase, Medline, PsycINFO, Global Health, CINAHL and Web of Science) were searched for articles from January 2000 to September 2023. A results-based convergence synthesis was used for data analysis and reported using PRISMA guidelines. RESULTS: Of the studies screened (n = 29,687), forty-four fulfilled the predetermined criteria and were included. Our findings relating to the experiences and treatment approaches of MBC are broadly themed into three parts. Theme 1-Navigating through a threat to masculinity: describes how males experienced the illness reflecting on detection, diagnosis, coming to terms with breast cancer, and disclosure. Theme 2- Navigating through treatment: captures the experiences of undergoing breast cancer treatment/ management following their diagnosis. Theme 3-Coping and support systems: describes how MBC patients coped with the disease, treatment process, aftercare/rehabilitative care, and the available support structures. CONCLUSIONS: Men experience a myriad of issues following a breast cancer diagnosis, especially with their masculinity. Awareness creation efforts of MBC among the public and healthcare practitioners are urgently required, which could change the perception of men in promoting early diagnosis, adherence to treatments, post-treatment monitoring, oncological results and a better quality of life. Considerations for training, education and development of specialised guidelines for healthcare practitioners on MBC would provide the necessary knowledge and skills to enhance their practice through the adoption of person-centred and male-specific care strategies. Professional care intervention and support for MBC should not end after the diagnosis phase but should extend to the entire treatment continuum and aftercare including future research focusing on MBC specific clinical trials.
