Thyroid cancer is a type of malignant tumor. However, if it is detected early, diagnosed early, and treated early, it generally has a relatively good prognosis compared to other malignant tumors. Once a patient is afflicted with this disease, it is crucial to seek treatment promptly. Without treatment, thyroid cancer can spread to lymph nodes. Initially, the cancerous lymph nodes may invade surrounding blood vessels and nerves, leading to symptoms such as hoarseness. If it compresses the throat area, it can cause discomfort in the throat accompanied by breathing difficulties and coughing while drinking. If the optimal time for treatment is missed, cancer cells can spread, potentially moving not only to the lungs but also to the respiratory system and bones, among other distant sites.
