Based on the type of mass, you may have a fine needle aspiration, core biopsy, sentinel node biopsy, or another type.

A variety of sizes of needle can collect tissue in the lumen (core biopsy).

The sensitivity of small core biopsies is modest, due to sampling error, as the process is often patchy.

I had a core biopsy last summer on a breast lump, which was benign.

A vacuum-assisted core biopsy is done with a hollow probe that uses a gentle vacuum to remove a sample of breast tissue.

It is a noninvasive test performed on small amounts of tissue removed during the original surgery lumpectomy, mastectomy, or core biopsy.

Gail's doctor reached her on the phone to say her core biopsies had come back positive, and she had ductile carcinoma.

Ultrasound-guided core biopsy: This technique obtains breast tissue without surgery.

These core biopsies require only local anesthesia, similar to what would be given during a small dental procedure.

Radial scars are often excised to exclude malignancy; however, observation following a core biopsy may also be considered.
