Re: thyroid cancer common?
Yes, there was an article back a few months that the American Cancer Society said there was an increase in cases---although I don't recall the percentage.
Also, it tends to hit women, often late thirties and up, so it's quite possible that on top of that increase, your demographic of your bible group is the target for thyroid cancer as well.
I used to sit there and wonder what caused mine, now that the ordeal is over for a few years, I don't think about that aspect any longer. The silver lining about the women in your group affected is that you have a support group.
Wishing you a quick and easy and successful surgery!
