My endo is trying to wean me off carbimazole I am now on 5mg three days per week and my latest bloods are serum T4 11.6 pmol/L (7.0 - 17.0) serum TSH 2.06 mu/L (0.20 - 4.50). Gfr for kidney function is 61 (60 - 159). He says the carbimazole can be harmful to my kidneys and thyroxine would be better as its a natural hormone so wants to give me radioactive iodine if the graves returns - which I think it will because I am still having symptoms, especially anxiety!! I am anxious because I particularly don't want radioactive iodine as I have heard that there is a greater risk of getting cancer over a 6 year period but my endo says that it only targets the thyroid. I hAve done some research which states that the medics can't tell how long the radioactivity is in your system and when it has done its work on the thyroid it remains in other areas of the body, particularly the intestines- I have a friend that had it done 4 years ago and now has bowed cancer! Can a partial thyroid removal be elected rather than radioactive iodine?
