core needle biopsy

A core needle biopsy is a procedure that removes small but solid samples of tissue using a hollow "core" needle. For palpable (“able to be felt”) lesions,

A core needle biopsy is used when your doctor needs more information about a breast lump than a mammogram, ultrasound, or fine needle aspiration can give.

A core needle, or hollow core needle, can be used to get small tissue samples from a breast lump. The tissue samples will be sent to the pathology lab for examination. This procedure can be done in an office, clinic or hospital by a doctor who is trained in the technique.

Techniques for Core Needle Biopsy:

There are several different ways to do Core needle biopsies.it is depending on the size of breast or location of the breast mass in order to being sampled. The Freehand needle biopsy can be used for lumps or masses that can easily be felt. But if a lump is too small to be felt, or too deep to aim a needle at, there are another methods that use imaging and mechanical assistance: ultrasound-guided needle biopsy, stereotactic needle biopsy, and vacuum-assisted biopsy.

What to Expect During a Core Needle Biopsy:

You will be awake during the procedure, but your breast will be numbed with a local anesthetic. Your doctor will locate the lump by touch or with guidance from imaging technology. Your doctor will insert the core needle through your skin into the lump to take tissue samples. To ensure the accuracy of results, there are three to six samples will be taken. You should expect to feel some pressure during the procedure, but be sure to let your doctor know if you feel significant pain. After the procedure, you may have some bruising at the needle sites, but no scars. You will be able to return to work or home right away.

Getting Results From Your Biopsy:

Your tissue samples will be tested in the pathology lab, and a written report will be sent to your doctor. A negative result means that there wasno cancer. A positive result means that the mass is malignant, and more tests will be needed to get an accurate diagnosis.

Benefits and Risks of This Procedure:

A core needle biopsy has many benefit.it is more accurate than an aspiration and less invasive than an open surgical or excisional biopsy. The needle biopsy will leave no external or internal scars, and so it will not affect future breast imaging studies. There is always the chance that the needle may miss a malignant area, but your doctor will try to minimize this possibility. A core needle biopsy is not aperfect treatment of milignant, and it will not remove all of a malignancy. If your results come back positive for cancer, you will need to consider more tests and treatment again.
