I saw my onc today for my usual 3 month visit. I told him I had chosen not to take the synthroid that had been recommended by my family physician, because of my concern with taking the drug. I showed him this article:
http://www.asco.org/ASCO/Abstracts+&...stractID=31728 which he read.
He did not feel the article contained anything substantial in content. The results of the study really showed nothing significant, in his opinion. He said that thyroid function is much more complex than things that were listed here. In his opinion, this was "someone who was wanting to write a paper." If one of the consequences of hypothyroidism is weight gain, that is also of concern to a hormone postitive breast cancer patient because fat cells emit hormones.
To my surprise my TSH was 2.91 today, and in recent years it has always been "4 something", so I doubt that I will start the synthroid. There has been some discussion on this board about the use of synthroids and breast cancer recurrance, so I wanted to share with you what I learned today.
