Does everyone have brain MRI's?

[jener8er]

Hello everyone, I have been doing some research into ER/PR- breast cancer and brain mets - it seems this is much more common in hormone negative patients. I am er/pg-, strongly Her2+++, pre-menopausal (38). Should I push for a brain MRI? I've never had one. I'm about to finish my 1 year of Herceptin and want to make sure I've done everything I can. Bone scan/PET have been normal.

Thanks for your help.
