I'm sorry you are back. It's not fun, is it?
It appears that you have a new primary. Breast cancer doesn't jump from one breast to the other. So with your new cancer being in the other breast, it is almost certainly a new primary. Even if it was in the same breast, if one cancer was ILC and the other IDC, that would be another way to distinguish between a recurrence (which would be ILC) versus a new primary.
Once any of us have been diagnosed one time, we are all higher risk than the average woman to be diagnosed a second time, with a new primary. That's a little secret that too many oncologists don't tell their patients. The further out someone is from diagnosis, the greater the risk, simply because we're older - all women become higher risk as they get older (the greatest risk years for breast cancer are our 60s and 70s) and it's the same for us. A new primary might be in the same breast or the opposite/contralateral breast and it might be a cancer that is similar to the first cancer or it might be completely different.
This board is full of people who've returned with a second primary. For many of us, it's 10 years or more; sometimes even 20 years. My second primary hit when I was 61 - I was just into those highest risk years. Like your situation, mine was also in the contralateral breast. While both my diagnoses were IDC, the presentation was very different, with just a microinvasion and DCIS scattered throughout my breast the first time, and a small solid mass with no DCIS the second time.
Good luck tomorrow! I hope it goes well.
