This is the first group I joined after the forums here on Mayo Clinic Connect:
Living with Low Anterior Resection Syndrome: https://www.facebook.com/groups/lwlars/about
More recently I heard about and joined: COLONTOWN®
"a unique, online community of more than 120 “secret” neighborhoods [on Facebook], dedicated to the exclusive use of colorectal cancer patients, survivors, and caregivers. There are neighborhoods focused on patients with different stages of disease, the differing types of treatment, and special interests – such as CRC clinical trials, young-onset CRC patients, and local support groups. Each single group is led and cared for by a “Neighborhood Admin,” themselves living the experience that is the topic headlined and under discussion in the group that they lead. Check out our list of neighborhoods at the link below; to join a group, simply send a friend request to the admin listed, and then send them a message requesting to be added. https://docs.google.com/spreadsheets/d/1zTi75-cNR1K2-ACmulA3TTnjfOtxwkpe87m7n0oQSgc/edit?usp=sharing".
