2 weeks ago I was diagnosed with DCIS from a biopsy after a suspicious mammogram. Yesterday I had an MRI and they just called me to tell me that there was a mass in my other breast that now needs to be biopsied. I had just sorted out the idea of lumpectomy + radiation in my head and now this seems like it may possibly change things.

Can you please help me sort out what the chances of this thing being cancer in the other breast are? All of the information is spinning right now. How common are false positives? Rare? Likely? Middle of the road?

Then what for treatment? Does this mean double masectomy is more likely vs lumpectomy?

    Just like you my MRI found something in my right breast that the original mammogram had missed. Plus it found a second mass in the left breast, but that turned out to be normal tissue, so, a false positive.

    I had planned on having 2 lumpectomies, plus radiation but the pathology of the second tumor, high grade, ER/PR negative, scared me and I decided to have a BMX. I figured if my breasts could grow such fast growing tumors then I didn't need them hanging around any more. MY BS said I made the right decision.

    You should have a frank discussion with your surgeon about your options after you have the new site biopsied.

    I think it's pretty common to have false positives. Given the dcis, they will be extra cautious and thorough. I had 2 areas in my opposite breast, they biopsied both and both were benign. Good luck!

    Courtney...so sorry you are going through this. Something similar happened to me. A small IDC tumor was picked up on a 3D mammo. I was scheduled for a lumpectomy until the pre op MRI picked up 5 suspicious areas that need to be biopsied. I was sure it was a death sentence. Fortunately only one of the five turned out to be malignant and it was ILC which often does not show up on mammo or u/s. So YES its very common to get false positives on MRIs. Ty not to panic until you get the results. Good luck and keep us posted.
