A Bit Spooked by MRI

Hi everyone,

I was hoping to never post here, but everyone seems to be so kind and helpful, and I've been lurking for a long time so figured I'd start posting, even if I hope my worry is short-lived. I'm 29 and have had chronic pain in my right breast for about 3 years. I was very taken aback by how sudden the pain was, and my doctors sent me for both a U/S and mammo at the time (both showed nothing; mammo also showed my breasts were very dense, obviously). The pain has continued on and off for the past 3 years, but was never tied to a mass. I was sent for a US after my annual gyn appointment this year, which found a benign lymph node and nothing else. I became concerned in August when I had one-time discharge from the same nipple. My gyn ran blood tests, which came back normal. She suggested a mammo, but based on the dense breasts finding from a few years ago (and my better insurance now), I demanded an MRI.

I got the MRI on Monday, and my results came through yesterday. My Dr still hasn't called me to go over them, but they basically say (I know the interpret your report thread is closed for the time being):

Similar appearing areas of nonmass enhancement at right 5:00 axis and right 12:00 axis.

At the right breast 5:00 axis, 1 cm posterior to the nipple, there is a 0.4 x 0.8 x 0.6 cm area of nonmass enhancement (axial image 38/192, sagittal image 83/298).

At the right breast 12:00 axis, 6.5 cm posterior to the nipple, there is a 0.5 x 0.9 x 0.8 cm area of nonmass enhancement (axial image 112/192, sagittal image 82/298).

Amount of fibroglandular tissue: Extreme fibroglandular tissue.

Background parenchymal enhancement: Minimal symmetric.

Biopsy of the right breast is recommended.

BI-RADS 4: SUSPICIOUS

I am obviously freaking out, these descriptions seem so non-specific. I don't even know what these sizes mean, in comparison? My doctor still has not called me. A friend who is in medical school and considered doing OB before deciding to do a different specialty has been helpful, but I guess I figured I'd post in case something comes of this and it could be helpful for others to see. I do want to thank all of you; I don't think I would have been insistent about the MRI without this website. It feels like I know so many people my age who are getting sick; so many more than the statistics would seem to bear out. Sending lots of support to everyone here.
