Breast Metastasized

My journey started as simple 1.8cm in breast with 1 lymph node. Bone scan came back all clear. The CT with contrast showed a mass in the liver. Oncology called and wants to move up my appointment to start treatment and I said—I haven’t even had a pet scan yet, (next week) nurse ‘he has seen this a lot and for sure cancer’—what? First, the chances of being in liver but not in bone first is small. She said a biopsy likely will be done regardless of what pet says.

1st-Has anyone had met go to liver but not bone?

2nd-Your experience with this sort of urgency for treatment before you finish pet scan/biopsy?

3rd—has anyone had a CT come back as suspicious but pet scan fine and found cancer with biopsy?

Has anyone used anything outside of chemo to treat with medical oncology bc I do not want chemo unless there is nothing else available to treat.
