Neck swellings vary in origin and nature depending on where they occur. The most common type of neck swelling is a goiter. Most of the thyroid swellings are benign, but the incidence of thyroid cancer has been increasing in recent years. In addition to thyroid swellings, lymphatic metastases from tumors elsewhere in the body, hematologic disorders, enlarged primary lymph nodes, lipomas, fibromas, and nerve sheath tumors are also common. Among them, the most common lymphatic metastasis is the metastasis of nasopharyngeal and pharyngeal tumors, such as nasopharyngeal, laryngeal and hypopharyngeal cancers, which are highly prevalent in Guangdong. Once the neck swelling is found, go to the hospital as soon as possible so as not to delay the disease and miss the time of treatment.
