Question
Hello doctor, I am 16 years old this year, I have had a dry cough without phlegm for almost 1 month now, I still have a stuffy nose on one side, if I have a stuffy nose on the right, I can breathe on the left, and if I have a stuffy left, I have to breathe, early in the morning I'm good. spit out green sputum. So let me ask, is a dry cough without phlegm, a stuffy nose on one side is a sign of nasopharyngeal cancer? Because I saw it for so long that it didn't go away. Thank you doctor.

Hello. With the question "dry cough without phlegm, stuffy nose on one side is a sign of nasopharyngeal cancer? "Doctors think this is not a symptom of nasopharyngeal cancer. By cough, green sputum as you describe is likely acute rhinosinusitis. Therefore, you should see an Ear - Nose - Throat specialist for endoscopy, X-ray to help diagnose and have an appropriate treatment regimen. You can go to the hospitals of Vinmec Health System for more specific advice from doctors.
