Certain factors can increase the risk of developing thyroid cancer, although having one does not mean you will definitely get the disease. A family history of thyroid cancer, inherited genetic conditions, and previous exposure to radiation around the head and neck can raise the risk. Thyroid cancer is also more common in women and may occur at different ages. If you notice a lump, swelling, difficulty swallowing, or changes in your voice, do not ignore them. Consulting the best thyroid specialist in Chennai can help identify unusual thyroid changes early and guide you toward appropriate tests and treatment.
