Thank you. I was told a marker is what grows my cancer. i.e. 100% estrogen 95% progestogen, HER 2 (and situ ?)
Tumor markers can help doctors understand the stage, growth, and seriousness of your cancer. Ki-67 is a biomarker test for people with breast cancer. It is one of many different tests available.

The clips are to help with radiation, but I have been having a reaction to a titanium clip and wanted it removed. So are they removing a marker or a clip with surgery? It gets so confusing.
