I also have very dense breasts. After the first tumor was noted on MRI, followed by lumpectomy, I asked the surgeon about MRI because I was worried about the other breast. Good thing she agreed since the oncologist did not think I needed an MRI -- well, the MRI showed a second tumor in the same breast on the opposite and inner upper side which turned out to be neuroendocrine cancer which is highly aggressive and doesn't usually start in the breast tissue. Had we not gotten that MRI, my future would be quite different. The other breast was clear (thank goodness). Since that time, the oncologist puts in for 3D mammograms for me and I still have PET scans performed because of the neuroendocrine diagnosis. If it was just the original invasive ductal cancer, I would not be receiving the PET scans.
