Women cancer carers have consistently been found to report higher levels of distress than men carers. However, there is little understanding of the mechanisms underlying these gender differences in distress, and a neglect of rewarding aspects of care. We conducted in-depth semistructured interviews with 53 informal cancer carers, 34 women and 19 men, to examine difficult and rewarding aspects of cancer care. Thematic analysis was used to analyze the transcripts.
