An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration biopsy.
Vacuum-assisted breast biopsy (VABB) is a more recent version of core needle biopsy using a vacuum technique to assist the collection of the tissue sample. Similarly to core needle biopsy, the needle has a lateral ("from the side") opening and can be rotated, allowing multiple samples to be collected through a single skin incision.
In 1981, the first fine-needle aspiration biopsy in the United States was done at Maimonides Medical Center. [1] The modern procedure is widely used in the diagnosis of cancer and inflammatory conditions. Fine needle aspiration is generally considered a safe procedure. Complications are infrequent. [2]
Vacuum-assisted breast biopsy (VAB) is a minimally invasive procedure to help in the diagnosis of breast cancer. VAB is characterized by single insertion, acquisition of contiguous and larger tissue samples, and directional sample capability. It also offers 10x the tissue of core needle biopsy. [1]
It’s a commonly-used diagnostic tool that can help your doctor determine whether you have cancer. But a breast biopsy isn’t the same for all patients.
It has been widely reported in the literature that 10-30% of patients with a diagnosis of LCIS on core needle biopsy will receive an upstaged diagnosis after excisional. [13] If LCIS remains the only diagnosis after the excisional biopsy, NCCN guidelines recommend clinical follow-up every 6–12 months with annual diagnostic mammograms. [15]
