Tsh is thyrotropin, thyroid cancer patients’ Tsh generally needs to be controlled between 0.1~0.5mU/L, higher than 0.5mU/L can indicate recurrence. The preferred treatment for thyroid cancer is surgical resection, and a slight increase in Tsh can generally occur after surgery, mainly because the thyroid gland can secrete thyroxine, and once it is removed it will lead to a decrease in the level of thyroxine in the body, thus resulting in a feedback increase in Tsh. After thyroid surgery, generally speaking, thyroxine tablets can be taken as a way to prevent hypothyroidism, inhibit the elevation of tsh and reduce the probability of recurrence, meanwhile, one should go to the hospital for rechecking on a regular basis, and in case of recurrence, one should be treated in time. Meanwhile, one should go to the hospital regularly for review and timely treatment if there is any recurrence. If there is any discomfort after the treatment of thyroid cancer, one should consult the doctor in time and standardize the treatment under the guidance of professional doctors to avoid delaying the condition.
