Thyroid cancer causes a decrease in antibodies

Thyroid cancer is a common endocrine tumor in clinical practice, which can be caused by a variety of factors such as genetics and endocrine disorders. Thyroid cancer can cause a decrease in antibodies, which is mainly due to the recurrence of thyroid cancer or radioactive iodine treatment. At this time, you need to go to the hospital in time to find out the cause and take targeted treatment plans.

1. Recurrence: Even if thyroid cancer patients undergo surgical resection, there is no guarantee that the tumor will not recur again, so it will lead to a decrease in antibodies. At this time, a clear diagnosis can be made by combining thyroid ultrasound examination, fine needle aspiration cytology examination, etc. If it is confirmed to be a recurrence, surgical resection and lymph node dissection should be performed in time;

2. Radioactive iodine treatment: Radioactive iodine-131 will mainly damage thyroid tissue and lymphatic tissue during the treatment of thyroid cancer, which can lead to apoptosis of lymphocytes in thyroid tissue, thus causing hypothyroidism, which can be manifested as a decrease in thyroid cancer antibodies. The main treatment is thyroid hormone replacement therapy, and oral levothyroxine sodium tablets are taken as prescribed by the doctor to promote the body's recovery;

3. Surgical treatment: Surgical resection is the main method for treating thyroid cancer, but for tumors with low differentiation or distant metastasis, iodine-131 radiotherapy may be required after surgery. If the antibody decreases due to tumor recurrence, surgical treatment and radioactive iodine treatment can be performed again according to the condition;.

4. Others: In addition to the above reasons, thyroid cancer patients may also suffer from hypothyroidism after radioactive iodine-131 treatment. At this time, you need to take levothyroxine sodium tablets under the guidance of a doctor to promote the body's recovery. You should also pay attention to rest and avoid overwork.
