There is a Facebook page for survivors of Granulosa Cell Tumours. It's very active and awash with support and information. If you are interested in joining look up GCT Survivor Sisters! through the Facebook search engine. That will bring you to the right page (although you won't be able to see the page itself as it's a closed page) However, there is a space for you to request to be added. The administrator will then see you in the queue to be added.
