Conversation: The conversation between human and AI assistant.
[|Human|] An 8 year old boy from my church was taken to the hospital today with chest pains.  They found that he has a mass putting pressure on his heart and are transporting him, via helicoptor, to a childrens hospital.  I had asked his mother last week about his face looking a bit swollen.  Do you have any idea what the mass might be?
[|AI|]  Hi, Yes, it's possible if mass is causing compression over and surrounding blood vessels it may lead swelling of face. Mass can have the number of causes. Common cause is lymphoma is a type of blood cancer. However, we cannot say the unless we do biopsy of the mass. So It's unwise to discuss regarding diagnosis until CT scan and biopsy is done. Hope I have answered your query. Let me know if I can assist you further.
