👉 Tonsils are small, white soft structures located at the back of your throat. They help in regulating your mucus and preventing infections from entering your body. Tonsils can be enlarged or inflamed due to various reasons such as chronic obstructive pulmonary disease (COPD), allergies, and certain medications. If they become infected, they can cause symptoms like a sore throat, difficulty swallowing, coughing up脓性分泌物，and sometimes even cancer if left untreated.
