I am old and i do not know much about breast cancer.
I have a young daughter i think she has breast cancer she is not sharing with me.
I would like to know is it possible for cancer to start in other parts of the body and then go to the breast .
I did find a similar question here
thought ill ask
Can breast cancer start in another part of the bod
Metastatic cancer is a cancer that has spread from its primary site (the part of the body in which it developed) to other parts of the body. If cells break away from a cancerous tumor, they can travel to other areas of the body. There, they may settle and form "colony" tumors. In their new location, the cancer cells continue growing. The spread of a tumor to a new part of the body is called metastasis.
So it wouldn't necessarily be breast cancer so much as cancer in the breast, but according to this article, Yes. It is entirely possible.

I suppose it's possible but I doubt it.. Usually it's going to be carried off by the blood stream and then lodges elsewhere like the liver and other places where the blood flow is more significant. The breasts are not areas with significant blood flow..
