Hi Justine, I underwent a lumectomy and didn't get clear margins. If I did they would have left behind all the early stage cancer found during MRI after my surgery (it did not show up in ultrasound). I'm now booked for a double mastectomy/reconstruction in April. Just finished 6 months chemo. I'm 42, with a family and for me this is the best I could do to be here for them.
An MRI can get a clearer picture of what's in your breast. It's not covered by Medicare, mine cost $600. Most doctors don't refer for breast MRI as standard mainly due to the cost (as far as I can tell from my research). But this was game changing for me.
I have multi focal disease, ie more than 1 primary and they said its very unusual to have unrelated areas of disease in one breast.
Unusual is not impossible.
I'm relaying this information not to scare, but to inform. I had never heard of breast MRI and wish I knew about it earlier. I also wanted all the information I could get to be the best informed I could be, that way I could make better decisions with the medical team.
Good luck with your decision making, chemo is crap but manageable. Maybe see the oncologist before deciding, to get more facts. Decisions are the hardest part of navigating this journey because everyone is different and only you can decide whats best for you.
Take care
Louie
