Religion and spirituality often influence how people experience illness, death, and grief. The roles of religion and spirituality for parents who have lost a child to cancer remain underexplored. This study aimed to describe how cancer-bereaved parents talk about religion and spirituality when reflecting on their experiences. Participants whose children died of cancer one to six years prior to participation completed a one-on-one semi-structured interview. Interview transcripts underwent qualitative analysis. Content pertaining to religion and/or spirituality underwent subsequent in-depth analysis to identify themes. Of 30 interviews analyzed, 28 contained religion/spirituality content. Four themes arose: (1) life after death, (2) divine control, (3) evolution of faith after loss, and (4) religious and spiritual interactions within the medical community. The absence of supports for religious and spiritual needs represents a gap in bereavement care. Future work should clarify needs and explore potential interventions.
