Seasonal variation in diagnosis has been reported in a variety of cancers including acute myeloid leukemia, lymphoma, melanoma, breast cancer and childhood cancers [1, 2, 3, 4, 5, 6].

Understanding the seasonal pattern of diagnosis of thyroid cancer may allow healthcare resource allocation as well as offer insights into disease pathogenesis.
