In two related studies, members of breast cancer self-help groups and
prostate cancer self-help groups were interviewed. In this paper, comp
arisons between the groups are made and implications discussed. Given
the substantive differences in self-help group experience, we argue th
at support needs and appropriate interventions cannot be assumed to be
the same for men and women. Because men emphasize the importance of i
nformation and advocacy, they are well served by large meetings, exper
t speakers and efficient organization. Because women emphasize the imp
ortance of intimacy and peer knowledge, they are well served by smalle
r group discussions, a focus on emotional support and friendship, and
by less emphasis on business, advocacy and outreach activity.
