Different range of diseases: thyroid tumor is a relatively clear disease; thyroid nodule can be thyroid tumor, thyroid cancer, acute goiter, thyroid cyst, etc.. Therefore, the range of thyroid nodules is larger. 2. Different symptoms: the typical symptom of thyroid tumor is a lump in the neck, which is usually painless, and the lump can move up and down with swallowing; the typical symptoms of thyroid nodule are breathing, difficulty in swallowing, and fullness in the throat. 3. Different treatment modes: when thyroid tumor is a benign tumor, it can be treated by surgical resection. If the thyroid nodule is malignant, it usually needs lymphatic cleansing or radiotherapy; when the thyroid nodule is benign, there is no pressure and other symptoms, so there is no need for special treatment, and if it is malignant, it can be treated by surgery to remove the whole or part of the thyroid gland. It is recommended that patients should seek medical treatment in time, and diagnose thyroid tumor and nodule through various examination methods by doctors, so that they can be treated in time.
