Hugs and prayers Barb, I bet they are just being overly cautious. At least you'll know after the biopsy? This time last year I had laser guided biopsy in four spots in my breasts, one would not have been bad at all, but all four (took about six hours) were exhausting. Mine were suspicious but not cancerous so I'm taking the anti-breast cancer drug for five years. Even if you end up having to take synthroid it shouldn't be too bad.
