Increased thyroglobulin antibodies after taking medication after thyroid cancer surgery may be a symptom caused by inflammatory stimulation at the wound site, or it may be a recurrence of thyroid cancer, which needs to be treated accordingly. 1. Inflammation: patients may have a short-term increase in globulin antibody after thyroid cancer surgery, which is usually a large molecule protein secreted by thyroid follicular epithelial cells. 2. Thyroid cancer recurrence: Thyroid ultrasound, thyroid function test and other tests are needed to determine whether thyroid cancer is recurrent or not, and appropriate treatment is needed after diagnosis. After thyroid cancer surgery, patients should follow the doctor’s instructions to use medicines in daily life, avoid eating spicy and stimulating food, and consult the doctor in time when the symptoms are abnormal.
