I find the quote very thought provoking, as I did Lani's post in this thread:
http://her2support.org/vbulletin/sho...eferrerid=1173 wherein the authors of a study posited that the thyroid hormone and estrogen may share the same pathway.
In 2004, I was treated for subclinical hypothyroidism. Try as I might, I could not get on a low enough dose of synthorid to keep me from having hyperthyroid symptoms. My doctor had me taking a very low dose. After about 4 months, I developed horrible urticaria, causing me to cease treatment. That lasted for almost a year after I stopped the drug, finally requiring a steriod cream to break the itching cycle. In April 2006, I was dx with triple positive bc. I have thought ever since that the synthroid was a bad actor in this.
Hopeful
