The clinical presentation of thyroid cancer varies because of its many different pathological types and biological characteristics. It can coexist with multiple thyroid nodules, most of which are asymptomatic. Occasionally, a nodule or lump is found in the anterior neck area, and some lumps have been present for years but have only recently grown rapidly or metastasized. Some patients have no complaints of discomfort for a long time and only become aware of metastases in the cervical lymph nodes, pathological fractures, hoarseness, dysphagia, dysphagia or even Horner’s syndrome at a later stage. Local signs also vary, from asymmetric nodules or masses in the thyroid gland to masses within the gland that move up and down with swallowing. The mass is fixed when the surrounding tissues or airways are invaded. In some patients with thyroid cancer, the first symptoms may appear after the tumor has metastasized to other parts of the body, such as the lungs or bones. If you have any pain or symptoms that are difficult to explain, you should see your doctor. Although thyroid cancer is usually slow-growing and curable, it can be widely invasive and fatal.
