Thyroid cancer detected incidentally and less than 1 cm may warrant only observation, whereas some cancers such as anaplastic thyroid cancer requires urgent intervention. Advances in the field of oncology have been revolutionized by the extensive study of tumor microenvironment (TME). The introduction of immune check point inhibitors resulted in a major shift in the understanding of differentiated thyroid cancer. Inflammation related to thyroid cancer involves various molecular patterns of cytokines and chemokines. They form the major targets for novel immunotherapies. Addition of discovery of newer tumor markers has significantly contributed to cancer management. Tumor immune escape is an important mechanism of oncogenesis. Innate immunity forms the major defense of the body to tumor cells. Polymorphonuclear leucocytes, macrophages, and lymphocytes form the defense that target tumor cells. The aim of this review is to comprehensively discuss the dynamic immune system, various oncogenic pathways and novel tumor antigens like cancer testis sperm associated antigen (SPAG9).
