How to watch for brain mets?

If you have had node involvement you are correct that a stray bugger has been camped out up there because bc is systemic. I know from experience. Please have a brain scan. Anyone else who is dizzy, having eye problems, balance problems, being a klutz, headaches (and it can be only once) should not try and rationlize what it is. Denial won't help treat it but early detection will. Please get an MRI.
