When there are small lumps in the neck, the main consideration is lipoma and lymph node enlargement. Lipoma is a benign tumor, and if it is small, it does not need special treatment. If it is lymph node enlargement, attention should be paid. The causes of lymph node enlargement mainly include inflammation, tuberculosis, and tumor. If it is caused by inflammation, such as acute tonsillitis, inflammation can be controlled at this time, and lymph node enlargement may disappear. If the lymph nodes are enlarged due to malignant tumors, such as thyroid cancer, the primary focus needs to be removed as soon as possible, so as to achieve better prognosis.
