In brief: Cancer or not
A fine needle biopsy of the breast is done when there is a lump or bump the surgeon can feel.
A hollow needle is put into the lump to get some cells, which are then looked at under the microscope. If there is a cancer, the fine needle biopsy might diagnose it, but it's not 100%. Other things such as fibrocystic breast disease or fibroadenoma (benign lump) can be diagnosed this way.

In brief: Whether there
are malignant or suspicious cells in the aspirate, which would prompt surgical excision.
In the US, fine needle aspiration is not commonly performed on breast lesions due to a variety of reasons. Needle core biopsy is generally the standard.

In brief: Pap Smear of Breast
Fine needle aspiration (fna) breast biopsies involve drawing cells out of a lump for definitive dx.
If cancer cells are seen, it is very reliable; however, a benign result can (rarely) miss a cancer. Therefore, our preference these days is to do a core needle biopsy (+/-vacuum assisted). This removes tissue rather than cells and is more reliable for diagnosis.

In brief: Not the whole story
Fine needle aspiration is operator dependent especially in small and deep breast mass.
Suspicious breast mass should consider complete excision for pathologic extermination.
