Hello,I was recently diagnosed with thyroid cancer and thyroiditis. FNA reports included oncocytic variant, Hurtle cell and tall cell (with possible dedifferentiation). I have a 2.2 nodule on the left side of my thyroid and metastasis to the lymphnodes on the left side. I am also 7 weeks pregnant. I was advised by two endos to terminate the pregnancy and go forward with surgery. A second opinion from Johns Hopkins also advised this. A thyroid specialist at the IGR (cancer center in France) said to wait until the 6th month of pregnancy to have surgery. Could delaying the surgery by a couple of months affect my prognosis in terms of further metastasis (to lungs etc) and future recurrences of the cancer years, even decades from now? Is delaying RAI until after delivery a problem with these more aggressive types of cancer?Could my cancer turn into an anaplastic cancer if I delay treatment?
Welcome to Chat Doctor . Thyroid cancer is normally slow growing so waiting for second trimester for surgery is one option. However, as it is a differentiated possible tall cell variant which has slightly worse prognosis and chance of changing to the anaplastic variant it may be better to for termination of pregnancy, surgery and Radio iodine therapy.  You can always plan your pregnancy after complete treatment of your thyroid cancer... Hope this answered your query.
