Oh, and also, I am not sure of your age, but I got a mammogram recently. Luckily they gave me the results right away but because I am only 27, my breast tissue was far too dense to get a good look. They didn't see anything suspicious but could not rule out something small "hiding". They recommended a breast MRI, which I had and it was all normal. Just to give you some relief incase they want to repeat the test or do something more diagnostic, like an MRI. Doesn't mean something is wrong. I actually had a surgeon look at my mammogram slides and he said "Looks like a typical 27 year old, which means I can't see much of anything". He agreed an MRI, although not really necessary, would be needed to get a completely clear reading.
