  • On the other hand, longer survival of breast anti tpo antibodies hyperthyroidism vs hypothyroidism patients with anti-thyroid antibodies could be due to the fact that these women are taking additional medications that might be beneficial for breast cancer. This is expected, since anti-Tg is a well-established marker in differentiated thyroid cancer DTC diagnosis and is considered a less specific marker in thyroid disease compared to anti-TPO [ 23 ].
