Harnessing Sorority for Breast Cancer Support: The INEN ‘Club de la Mama’ Experience in Peru

Objective: To explore how sorority is expressed among women with breast cancer participating in the “Club de la Mama” (Breast Club) support group at the National Institute of Neoplastic Diseases (INEN), Peru, through an analysis of their experiences, perceptions, and the perceived impact of the group on their illness journey. Materials and methods: A qualitative phenomenological study was conducted with a purposive sample of 56 women diagnosed with breast cancer who were active participants in the “Club de la Mama”. Data were collected through semi-structured interviews and focus groups. Thematic analysis was carried out using ATLAS.ti 8 software. Results: Four key dimensions of sorority were identified among participants. First, emotional support and self-esteem emerged as a central theme, with the group providing a safe space for emotional expression that helped reduce anxiety and depression. Second, trust and support network building was evident through strengthened interpersonal bonds and a growing sense of mutual reliance within the group. Third, mutual care and joint learning highlighted the importance of exchanging knowledge about the disease and coping strategies, fostering collective resilience. Finally, participants expressed a strong appreciation for unity and shared vulnerability, recognizing the power of solidarity in navigating their illness together. Conclusions: Sorority plays a fundamental role in the lived experience of women with breast cancer, promoting emotional well-being, strengthening support networks, and enhancing personal empowerment. The integration of such peer support spaces within the healthcare system has the potential to improve patients’ quality of life and contribute to better adherence to treatment.
