Hi All, Have a mom with a 11mo old BF baby (frequently BF!). Mom has a tumor/cyst, non-cancerous, on her thyroid gland, size of a tennis ball. Tumor/cyst does NOT affect the thyroid; thyroid is working normally. The tumor/cyst had been drained twice. Dr wants mom to start taking Synthroid, 50mg once a day in hopes of shrinking the tumor/cyst. Dr wants to suppress moms thyroid by using the Synthroid, so that moms thyroid will stop making its own hormones, the tumor/cyst will maybe shrink, and she will then hopefully avoid surgical removal of the tumor/cyst. Mom is very concerned about babys reaction to the Synthroid and also her physical because of a history of hormonal imbalances. (BTW, she is a Medi-Cal mom) Can anyone offer any advice? Mom would rather have the surgery than the drugs. TIA! Jay
