Hello! My name is Maxine, I`m 26 and I have some questions concerning thyroid cancer and birth control. I was diagnosed with papillary thyroid cancer 10 months ago and had a full thyroidectomy . So far I have received 145 mci of RAI, 100 of which were given for treating lymph node metastasis . There are some undifferenciated areas on my CT scans (neck and mediastinum ) so I`m still in the status of a cancer patient. My therapy is 150 micrograms of Euthyrox. I`m considering starting another birth control measure in addition to using condoms. Is it problematic to use hormonal birth control while on Euthyrox, especially if the cancer is still present in the form of metastasis? I would appreciate your help, thank you.
