There are different types of online support groups to accommodate patients’ and caregivers’ diverse needs. Many groups have an open format, which means they have no time limit and few restrictions on who can participate. Others follow a closed format, in which members must register before participating.

CancerCare‘s online support group model resembles a message board structure and is asynchronous, as opposed to a live chat. This type of group is only accessible to registered members, and is available 24 hours a day, 7 days a week. Participants can write comments, answer questions, and read and respond to posts from other members—all at their own convenience and free of charge. All of CancerCare‘s support groups are moderated by licensed oncology social workers, though other organizations’ groups in this format may be moderated by volunteers or patient assistance professionals. Working with a professional oncology social worker may help patients and caregivers feel particularly safe to share difficult feelings, and may provide them with deeper insights into their situation and experiences.
