The most appropriate intervention for this patient is to facilitate an online chat with a patient of the same age who is undergoing a similar experience; it is okay that the cancers are different. The 13-year-old with Ewing sarcoma is not appropriate because of the age difference; they are at different developmental stages. The patient will benefit more from talking with a patient experiencing a similar situation than hearing from a young adult who beat cancer. Although support groups may be helpful, discussion with another patient the same age will be more appropriate.
