I had thyroid cancer along with a large tumor back in 2002. I had everything removed and had radioactive iodine twice. I"ve noticed that even though I'm only 43, I am starting menopause. I had my hormones checked by my doctor and he said I'm not. I disagree. Hot flashes, irregular periods, etc. I was looking into getting amberen which is supposed to help level hormones and help with menopause. Anyone know if that will affect how my thyroid medication works - (Armour)?
