Conversation: The conversation between human and AI assistant.
[|Human|] My boyfriend is has been having discomfort in his testicles lately. He has cysts that have been there for  a while, but his doctors have told him that it is nothing serious.  He wants to get a biopsy on it to see if it is cancerous or not. what would you suggest doing?
[|AI|]  Hello, It depends on "cyst" size. Usually cyst is not common in the testicles. Rather there are tumors.  It is not clear from your question whether he has cysts, tumors or just enlarged testicles. Most of the time, scrotal ultrasound gives information whether the testicular swelling are "normal" or "cancerous". In some cases, blood tests can also be helpful (beta Chat Doctor, AFP, LDH).  Hope I have answered your query. Let me know if I can assist you further. Take care
