How does thyroid cancer cause a decrease in antibodies?

Thyroid cancer causes a decrease in antibodies, which may be related to thyroid cancer itself, or to factors such as the patient's own immune system abnormality, hyperthyroidism, hypothyroidism, etc. It is recommended that patients seek medical treatment in a timely manner and receive treatment under the guidance of a doctor.

1. Thyroid cancer: If a patient has thyroid cancer, local lumps may occur, accompanied by symptoms such as hoarseness and difficulty swallowing. At this time, the patient's immune system will attack the thyroid tissue, causing thyroid cancer to cause a decrease in antibodies. It is recommended that patients use targeted therapy with drugs such as apatinib mesylate tablets and gefitinib tablets under the guidance of a doctor;

2. Abnormal autoimmune system: If the patient is under stress for a long time or has other diseases, it may cause abnormal autoimmune system, which may lead to thyroid cancer and antibody decline. It is recommended that patients take prednisone acetate tablets, dexamethasone tablets and other drugs for treatment under the guidance of a doctor;

3. Hyperthyroidism: If the patient suffers from hyperthyroidism, symptoms such as excessive sweating, palpitations, and weight loss may occur. At this time, the level of thyroid hormone in the body is high, and thyroglobulin antibodies are an autoantibody against thyroglobulin. When the level of thyroid hormone in the body rises, it will cause thyroid cancer and cause the antibody to decrease. It is recommended that patients take propylthiouracil tablets, methimazole tablets and other drugs for treatment under the guidance of a doctor;

4. Hypothyroidism: If the patient suffers from hypothyroidism, he or she may experience symptoms such as chills and fatigue. At this time, the level of thyroid stimulating hormone in the body is low, and thyroid stimulating hormone is one of the important hormones that promote human metabolism. When the level of thyroid stimulating hormone in the body decreases, it will cause thyroid cancer to cause antibodies to decrease. It is recommended that patients take drugs such as levothyroxine sodium tablets for treatment under the guidance of a doctor.

If the above symptoms persist or worsen, it is recommended that patients go to the endocrinology department of the hospital in time for a complete blood test, ultrasound examination, etc. to confirm the diagnosis.
