In the diagnosis of breast cancer uses these types of biopsy as needle aspiration, stereotactic.
Fine-needle aspiration biopsy. This method is used for biopsy of palpable (ie, those that be felt) breast tumors. In carrying out the procedure the patient is sitting. On the skin of the breast biopsy indicated the place and it is treated with an antiseptic. Further, the thickness of the gland entered a long, thin needle to the syringe. After the needle penetration into the interior of the tumor, the plunger is pulled several times. This technique of needle and syringe sucked a small amount of glandular tissue. If the puncture of the cyst is then sucked into the syringe fluid that was in it. Once all the liquid is pumped out the cyst, the cyst lumen of the cyst decreases and pain she has caused to be lost.
Stereotactic fine needle biopsy. This method is a biopsy that is taken with a needle multiple tissue samples from different locations of the tumor. In the case where the tumor is impossible to probe and it is located deep in the tissue biopsies used for mammography or ultrasound. The patient lies on his back on a table. Next, do a few shots of mammography or ultrasound at different angles to form a three-dimensional image as if to find out exactly the place the needle.
Thick needle biopsy. This type of biopsy provides a slightly larger-sized portion of the breast tissue. For its use of a thick needle, equipped with the cutting device. The advantage of this type of biopsy is that the larger-sized piece of tissue for histological diagnosis allows more precise set.
Stereotactic thick needle biopsy. When the tumor is not possible to probe and it is located deep in the tissue biopsies used for mammography or ultrasound. To do this, do a few shots of mammography or ultrasound at different angles to form a three-dimensional image as if to find out exactly the place the needle.
An incisional biopsy. This method consists in carrying out the biopsy excision of a small piece of tumor tissue. It is more like surgery. Naturally, this type of biopsy performed under local anesthesia. Often, incisional biopsy is performed when the results of aspiration biopsy is not enough reliable. As aspiration and incisional biopsy may sometimes give false results. However, their advantage - their speed.
Excisional biopsy. When a biopsy is conducted Excisionalmini-surgery, during which the doctor excised a part or the entire tumor. This procedure can not be considered curative, as in the case of cancer cells than the tumor itself is necessary to remove lymph nodes, or it may require even more extensive surgery. If the size of the tumor during the biopsy eksitsizionnoy less than 2.5, then the dissection is carried throughout the tumor. with large tumor size (more than 2.5 cm) removed only part of it.
Summarizing the data on the biopsy, you can specify the following:
Breast biopsy procedure is conducted to determine the nature of the tumor: it is cancerous or benign.
In the event of any signs of breast cancer final diagnosis is made only after biopsy.
A biopsy may be performed with a needle or by surgery.
Non-immediate biopsy techniques (using needles) have less stress on the patient and pose less risk of complications.
Nonsurgical biopsy methods may not always give a reliable answer.
For biopsy nonpalpable tumors using ultrasound or stereotactic biopsy.
In most cases (80%) biopsy results reject the malignant process.
