Women with a history of thyroid carcinoma have a greater than expected risk of developing breast carcinoma. This risk is most pronounced in premenopausal white women, who have received treatment for thyroid cancer. We report two patients with well differentiated thyroid cancer on follow up developing carcinoma breast, one patient 22 years and the other developing breast cancer 7 years after treatment for carcinoma thyroid. Both patients were detected at an early stage and were treated with curative intent. Both patients show no evidence of disease at the last follow up. Because this risk is appreciable throughout the lifetime of the individual, lifetime monitoring and breast cancer screening are important for all female patients with thyroid carcinoma.
