S4OM offers a searchable index of oncology massage therapists who have the necessary specialized training and who subscribe to the S4OM Standards of Practice. Currently, the Society for Oncology Massage is the only entity that requires proof of training and competency for listing in its locator service. There are many massage-oriented orgnaizations that allow members to indicate their specialties or certifications with little or no requirement of proof related to those specialities or certifications. There are also many individual therapists who will refer to themselves as "oncology massage therapists" or who will market themselves to clients living with cancer despite having little or no training related to cancer and massage. The Society for Oncology Massage's serachable index is currently the safest one-stop tool to find trained massage therapists who are able to work safely with anyone currently going through cancer treatment or with a cancer history.
Another tool that you will likely find useful in your search is our "Is Your Therapist Trained?" page.
