Over the past four years, 1018 patients with breast tumors underwent an ultrasonic examination both for the breast and thyroid gland. We found 24 cases (2.4%) of occult thyroid cancer by ultrasonography and performed radical operations in 13 cases. Six cases (46.2%) of these resected cases were included in "tis" or "t1" cases. Some of these cases were of advanced cancer with lymph node metastasis, local invasion or anaplastic carcinoma. Five of the 13 cases of radical operation on the thyroid gland had also undergone operation on breast cancer. In summary, we should inspect the thyroid gland simultaneously when we examine the breast with ultrasonography.
