What is metastatic breast carcinoma?

Spread: Usually means spead beyond the local regional areas - that is to lungs, liver, brain, bones, etc.

Cancer 'elsewhere': Metastatic cancer is cancer that has spread from its organ of origin to another part of the body. For example, the most common sites of metastases for breast cancer are the lungs, liver, and bone. Most breast cancers, when caught early and treated in a timely manner, do not ever spread to other organs.
