Thinking of you, Red.
For what it's worth, I had a very similar situation when I was 32 years old! I had a fine needle biopsy done right in the surgeons' office, and I don't remember any pain or terrible after effects. I also had my first mammogram done at that tender age and the calcification ended up just going away. I know this was back in the dark ages of breast cancer care, but I was quite freaked out (my youngest son was only 1 year old) that my 2 little kids would be motherless, and it turned out fine.
