We use the latest chemotherapy regimens and anti-estrogen therapies to achieve the best possible results for each patient. Some women may have the option of starting with systemic chemotherapy treatment neoadjuvant therapy before surgery is performed. Shrinking a tumor in advance through chemotherapy can avoid extensive breast surgery to remove a tumor.

Background Recent comparative studies have demonstrated several advantages of minimally invasive breast biopsy procedures over needle localization core surgical biopsy NLBx. Minimally invasive breast biopsy procedures take less time to perform than NLBx, cause less patient discomfort and cosmetic deformity, result in less artifact on subsequent mammography, and are more cost effective.

If a benign lesion is found, the patient can be followed with clinical examinations and mammography and an open surgical procedure is avoided. Biopsies can be obtained either with a fine-needle gauge or large bore and gauge needle.

However, the large-core biopsy is favored over fine-needle biopsy for several reasons: For larger, fixed, palpable lesions, image guidance is considered not medically necessary for performing an adequate biopsy. In these cases, palpation-guided biopsy is sufficient for locating the lesion and obtaining an adequate tissue sample.

However, image-guidance has been shown to be useful for directing the biopsy of non-palpable or vaguely palpable lesions. Palpable lesions that demonstrate a small area of clustered microcalcifications on a mammogram may be difficult to biopsy using palpation alone and thus may warrant image-guided biopsy.

Lesions that are difficult to biopsy using palpation are generally those that border on being non-palpable; non-palpable lesions are not amenable to palpation-guided biopsy.

Advanced breast biopsy instrumentation ABBI allows for a 2-cm core of breast tissue to be excised under stereotactic guidance in an outpatient setting. These investigators reported their initial experience with ABBI. Hospital charts from 89 ABBI procedures between October and July were retrospectively reviewed for patient characteristics, ABBI parameters, radiographic appearance, pathology, complications, and clinical follow-up.

The 9th patient was deceased at 6 months from an unrelated cause. In selected patients with invasive cancer and negative margins, ABBI may obviate the need for further local surgical treatment.

Furthermore, ABBI merits additional investigation as a therapeutic modality for early breast cancer. All of them underwent minimally invasive percutaneous VABB with an gauge needle.

In patients an ultrasound-guided procedure with a hand-held device was performed while in women stereotactic biopsy was carried out using a dedicated prone table unit with digital imaging. In each case the duration of biopsy was measured in terms of the total procedure time, room time and physician time.

There were no significant differences between the stereotactic and ultrasound-guided groups with regard to patient age, body mass index, menopausal status, history of parity, hormone replacement therapy, breast parenchymal pattern according to Wolfe's classificationfamily history of breast cancer, mass size and number of samples.

Ultrasound-guided biopsy was found to take significantly less time than prone stereotactic biopsy in every aspect of procedure duration.

The MQSA and FDA require documented training in Digital Breast Tomosynthesis prior to independent use in clinical practice. The same machines are used for both types of mammograms. However, diagnostic mammography takes longer to perform than screening mammography and the total dose of radiation is higher because more x-ray images are needed to obtain views of the breast from several angles.
