Need treatment: In short, there are blood tests, where certain proteins (markers) are looked for. These proteins in the blood potentially indicate cancer is present. I think that "cancerous cells in the blood" is just miscommunication between you and your oncologist. Ask you oncologist to re-explain everything. Your health and how to best treat you are serious matters.

Needs clarification: It could mean a variety of things. There are certain serum markers that can be tested for in blood that are produced by breast cancer cells and there are compounds in blood that can be assessed that are not produced by the breast cancer cells, but are byproducts of your body's response to the cancer cells. Your oncologist may be able to clarify things for you.
