I finally reached my Endocrinologist yesterday. Well, technically I reached the Fellow. It’s virtually impossible to talk to or see my actual Endocrinologist because apparently he’s some big fancy Thryoid Cancer specialist. Anyway, here’s a brief discription of my Thyroid cancer history and my questions along with the answers from the doc.
Diagnosis: Follicular Carcinoma Minimally Invasive
Treatment:
- High Does Radioactive Iodine in October 2003 followed by whole body scan to make sure all the thyroid cells are gone. Thyroid cells love to eat iodine so the long-standing therapy for Thyroid Cancer has been to attach a radioactive thingy to iodine and give it to the patient. The iodine finds its way to the thryroid cells and because it has a radioactive molecule attached to it, the thyroid cell is killed. Following the high does RAI, I had cancer screenings in 2004 and 2005 which were done by giving me the same radioactive iodine (much smaller dose) then doing a whole body scan to look for any glowing cells which would indicate Thyroid cells. If any thyroid cells are present, they assume the cancer is back.
- The past 2 years they’ve switched my cancer screening away from the RAI (thank goodness!) and now they shoot me up with Thyrogen then do a blood test to look for a protein that is produced by any active thyroid cells. I’ve been clean the last 2 years.
Questions:
- Complete thryoidectomy. They found 2 large tumors and diagnosed me with Follicular Carcinoma, Minimally Invasive.
- Radioactive Iodine- Will this prevent me from getting pregnant? Is there any risk of pregnancy related complications or birth defects from my previous RAI back in 2003? No. We recommend waiting at least 6 months to get pregnant after RAI because the effects <6 months are not well studied. You treatment is so far in the past that you should have no problems.
- Thyrogen injections- Is there any risk of pregnancy related compliations or birth defects from the injections I’ve received the last 2 years for my cancer screening? No. Thyrogen is a hormone that exists in your body already, we just give you a high dose. It clears your system really quickly. There should be no problem with this.
- Synthroid- I’m still on a suppressive dose of synthroid. Is there any risk of pregnancy related complications or birth defects from the high dose of synthroid I’m taking? The risk is that it will prevent you from getting pregnant. You’ll need your dose decreased so that it won’t impair fertility. You’ll also need your dose monitored during pregnancy because pregnancy can cause fluctuations in your hormone level.
- Can I breastfeed while taking synthroid? Yes. There is no problem with this. Synthroid in breast milk is minimal and the baby’s system will regulate and know how much of it’s own thyroid hormone it should produce. (this still doesnt sound good to me but what can I do. I have no thyroid so I have to take the synthroid)
So, that’s that. He basically said that I should be a lot more worried about my age than my history of Thyroid Cancer. Thanks, doc!
