I'm 44 and very healthy overall--a bit overweight, but no surgeries or major illnesses. Two weeks ago, during a routine mammo they found a density in my right breast. I had a subsequent ultrasound done 3 days later which confirmed "something" and am now scheduled for a biopsy this Thursday. (I was not told the size of the mass but afterwards I looked at the screen which noted 3cm.) There is a strong history of cancer in the family--Father died at 48 from stomach cancer, Grandmother (now deceased) and Mother had breast cancer so, of course, I'm trying not to be worried.
My question is--what are the differences in biopsies? In my research I've seen reference to core needle biopsy, fine needle biopsy, steriostatic biopsy and asperation? Is any one better than the other (ie, less instrusive, less painful, more accurate)?
