[|Human|] my son has a persistent sore throat for a month now. saw a doctor and they thought it was sinusitis, treated him with Zithromax for 5 days and now it is back. He had swollen lymph nodes in neck when seen 2 weeks ago. says throat is still sore. He is 20 years old and just quit smoking 2 weeks ago. He smoked about 3 years. Hes worried about cancer.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He may have some upper respiratory tract infection like sinusitis, and it leads to reactive enlargement of lymph node. He should go for fine needle aspiration cytology or biopsy of lump. It will give you exact diagnosis. Then you should take treatment accordingly. Don't worry about cancer. At age of 20 chance of cancer is very low. So just be relaxed. Avoid smoking. .
