A bulge on the outside of the throat may be a goiter, lymphadenitis, malignant tumor, etc. 1. goiter: insufficient synthesis of thyroid hormones, iodine deficiency, increased iodine demand, thyroid nodules, tumors, etc. can cause goiter, resulting in a bulge outside the throat. 2. Lymphadenitis: usually due to acute or chronic inflammation involving the lymph nodes in the neck leading to enlarged lymph nodes. The enlarged lymph nodes of acute lymphadenitis have pressure and pain and are soft, while the enlarged lymph nodes of chronic lymphadenitis are hard and the pressure and pain are not obvious. 3. Malignant tumor: If the patient has malignant tumor, such as thyroid cancer, nasopharyngeal cancer, etc., lymph node metastasis will occur in the late stage, which will cause swelling of lymph nodes in the neck, which will be manifested as a bulge on the outside of the throat. There may be other reasons for the bulge on the outside of the throat. It is recommended that the patient should undergo imaging examination to clarify the nature and cause of the lump, and then carry out treatment according to the cause of the lump.
