You can take a bath after thyroid cancer surgery if the wound is completely healed. Thyroid cancer is the most common malignant tumor of the thyroid gland and is currently the malignant tumor with the fastest increasing incidence. For thyroid cancer, surgery is the basic treatment for all types of thyroid cancer except differentiated cancer. If the thyroid cancer surgery goes well, the postoperative recovery is good, and after the wound has healed completely, you can take a normal bath. Currently, the common types of thyroid surgery include total thyroidectomy with lymph node dissection, etc. Iodine 131 treatment is routinely required after surgery, and the stitches can be removed within one week after surgery if the recovery is good. After the stitches are removed and the wound is completely healed, you can continue to take a bath without any special effects.
