Although men's cancer experiences have received limited attention within the field of psychosocial oncology, increasing attention is being devoted to the development and evaluation of men-centered programs. This scoping review describes this emergent body of literature, detailing the focus, participation, and impact of interventions designed to help men with cancer build illness-specific knowledge, adapt to illness, manage side effects, distress, and uncertainty, sustain relationships, and more. Striving to build on existing knowledge, research gaps and opportunities are discussed, including a need for stronger methodologies, more tailored and targeted supports, attention to the experiences of men with nonprostate cancers, and the explicit integration of gender analyses in the research process.
