Despite growing recognition of adolescents and young adults (AYAs) as a distinct oncological population with unique psychosocial needs, empirical evidence on how physical environments in community cancer care settings shape their wellbeing remains limited, particularly in Asian contexts. This study explores how the design and physical environment of a community AYA cancer care center in Singapore influences the psychosocial experiences of Malay-Muslim AYAs with cancer, addressing a critical evidence gap in culturally situated psycho-oncology.
