Steph -
No I have not had a mri --- does the ca2729 sometimes show for brain mets? I had my last pet scan in Sept, the same week as the last ca2729 - nodes were clear, only sign of mets was in the same spots in ribs, but nothing was worse or new. I'm not familiar with her2serum test. Is that a blood test? What would that indicate that the ca2729 doesn't about tumor cells circulating? thanks. Pam
