Punch biopsy (high-speed punch under ultrasonic view)

Punch biopsy done for clarification induration palpable or sonographic changes clearly visible. It is the drug of choice, especially for larger Tastbefunden and / or expected benign findings on palpation.

In this method (mostly) "shot" under ultrasonic view of 1.6 millimeter thick needle punching at high speed into the tumor to remove a tissue sample (larger aggregates of cells). Here, the guide sleeve is used, the cylinder network at that time several (at least three) (each about 1.6 cm) removed for microscopic examination. Due to the high speed of the punch form during the sampling itself is not ill, only a small skin incision under local anesthesia is required. Lower risk of infection and bleeding.

If the investigation carried out by an experienced doctor who works with ultrasound images, diagnosis almost as safe as the complete removal of abnormal palpation. "Malignant" safe punching results (ca.98%), as far as at least three samples were taken.

Stereotactic (X-controlled) biopsy procedure, stereotactic

Stereotactic is a collective term for a variety of biopsy, all under fluoroscopy but organized to work with different instruments for sampling. This differs substantially with the diameter of the needle or tube used and therefore the number of samples collected.

Methods or instruments to be used depends primarily on the size of the herd that should be investigated. Stereo Taxien mainly used in calcification (micro) in the chest. The calcium deposits are not visible on ultrasound, but can be located in a mammography.

During the examination, the patient is kept in a prone position on the operating table. The table has openings 25 through which extend a special centimeters checked chest down. Below the table is the X-ray apparatus and instruments essential biopsy.

For breast biopsy image computer by means of two mammography (hence the name Stereotaxy) calculated millimeters position suspects cooker (z. B. microcalcifications) in the chest and deliver the data to the biopsy instrument. The procedure is then performed under computer control, but under medical supervision. An additional shot after surgery allows direct control of therapeutic success. Modern digital image processing enables the representation of an enlarged and higher contrast than the suspect herd.

Extermination, removal of tissue by surgery (open biopsy)

When the striking findings can not be clearly determined by a minimally invasive biopsy procedure, stove completely surgically removed by a so-called open biopsy. Suspect stove removed from the breast - In this surgery, the patient - under general anesthesia.

Also with (especially bloody) fluid discharge from the nipple eye-catching open biopsy is often required for definitive clarification. Here, the milk is exposed channel filled before surgery with blue color solutions to find better during surgery can be.

Open biopsy is also required when due do a fine needle aspiration or core biopsy is malignant or precancerous proving process (malignant tumor, ductal Carzinoma-in-situ, DCIS).

Then a pathologist examine the nature of the tumor and determine whether the stove is completely removed.
