I would call the doctor and ask him to explain what it means prior to having the biopsy. I had my yearly mammogram in Nov, called back for 2nd mammogram, along with ultrasound and biopsy, that were all done the same day. It looks like that they can't rule out cancer so they want to do further testing, as was my case. I also had a breast MRI done later. That is done where you lie face down, you will have an iv. I know the anxiety is overwhelming. I have been there. I will say a prayer for you. I found that listening to meditations for anxiety helped me. You can find them on youtube. Also, call and see if they have had any cancellations, maybe they can put you on the list. The waiting is so hard.
