乳腺癌合并甲状腺癌致病因素的研究进展

甲状腺癌和乳腺癌是女性中最常见的两种恶性肿瘤。甲状腺和乳腺并发肿瘤在临床实践中较为罕见，但近年来这种双重恶性肿瘤的发生率有所增加。以往进行的研究主要集中在对侧乳腺癌发病率可能增加的问题上，而近期在患有乳腺癌的女性中发生甲状腺癌的风险升高引起了广泛关注，具体机制尚未被彻底了解，因此本文就这两种疾病之间的致病因素作一综述，同时评估这些因素在两癌并发中的病因学作用，以为临床实践提供更好的依据。

Research Progress on Pathogenic Factors of Breast Cancer Combined with Thyroid Cancer

Thyroid cancer and breast cancer are two of the most common malignant tumors in women. Concurrent tumors of the thyroid and breast are relatively rare in clinical practice; however, the incidence of such dual malignancies has recently increased. Researches conducted in the past mainly focused on the possible increase in the incidence of contralateral breast cancer, while the increased risk of synchronized thyroid cancer in women with breast cancer has attracted widespread attention recently. The specific mechanism has not been fully understood. This article reviews the pathogenic factors between these two diseases, and evaluates the etiological role of these factors in these double primary cancers, so as to provide a better basis for clinical practice.
