What are the common symptoms of thyroid cancer?

The common symptoms of thyroid cancer mainly include the following aspects: 1. Neck mass: This is the most common symptom of thyroid cancer. The mass is usually painless and moves with swallowing. Patients may discover this abnormality through self-examination of the neck. 2. Hoarseness or voice changes: Thyroid tumors may compress the nerves of the larynx, leading to hoarseness or changes in voice pitch. 3. Throat discomfort: This includes sore throat, a sensation of a foreign body in the throat, and difficulty clearing phlegm, which may be caused by thyroid cancer. 4. Difficulty breathing and swallowing: When the tumor is large, it may compress the trachea and esophagus, causing difficulty breathing and swallowing. 5. Neck swelling and pain: As the tumor grows, swelling and pain may develop in the neck. 6. Enlarged neck lymph nodes: Thyroid cancer may cause enlargement of the lymph nodes in the neck, which is another symptom that requires attention. If the above symptoms occur, prompt medical consultation and further examinations are necessary to determine the cause.
