A biopsy is the removal the sample tissue from a suspicious area and is especially powerful in the diagnosis of breast cancer. Its used when a mammogram or other imaging techniques reveal an abnormality or when a patient or health care provider finds a breast lump After the tissue is removed it is sent to a pathologist who examines it and determines whether or not the sample contains cancerous cells biopsy samples may also be used in disease staging and treatment design the types of biopsies are either a fine needle aspiration.
Or a core needle biopsy or an excision biopsy A fine needle aspiration can be used if a mass is discreetly palpable if you can really feel a mass and the mammogram or ultra sound is very suspicious and the clinical exam is suspicious so you always have to have that triple test the three all lining up in order to use a fine needle aspiration The fine needle aspiration and core needle biopsy procedures are very similar On the day of the exam no special preparation is necessary when you arrive at your doctor’s office the area to be biopsied is prepared by.
Cleaning and sterilization A fine needle aspiration is generally done without the use of local anesthetic the size of the needle use for an FNA is smaller than the needle used to inject an anesthetic The doctor inserts the needle targeting the center the lesion When the target is reached a very small pieces removed by suction this procedure is repeated two to four times to ensure that a large enough sample is obtained If the lesion cannot be felt the doctor may use an ultrasound other imaging technique to help guide the needle more accurately into the.
Suspicious area A final aspiration actually removes cells from that tumor and the pathologist can instantaneously look underneath the slides to make the diagnosis so the advantage is that we can get the diagnosis actually very quickly A core needle biopsy is similar to a fine needle aspiration except that a larger 11 to 18 gauge needle is used In contrast to an FNA, a core needle biopsy generally does employ the injection of a local anesthetic over the area to be sampled During a core needle biopsy, a small nick is made in the skin.
And the doctor then inserts needle through this nick At least three samples are taken from each suspicious area to ensure that an adequate amount of tissue is obtained In most cases, an imaging techniques such as ultrasound is used to help guide the needle into the desired tissue Steristrips are used to close the small cut and a larger bandage is placed on top to protect the wound A core needle biopsy can also be done in an office or in a breast imaging suite and this is taking larger samples of tissue from the tumor.
Either by palpating and by feeling and putting the needle into the tumor or by using mammography or ultrasound to find the tumor and so that the needle is placed directly into the proper location and this, a core needle biopsy removes actually chunks of tissue where the breast Parenchyma the breast cells in the structure of the breast tissue can be analyzed and we can definitively say is it invasive or is it noninvasive cancer Occasionally we have to use excision biopsy and those are situations where either the needle can’t collect enough.
Tissue or we’ve collected some tissue with the needle either a fine needle aspiration or core biopsy and there are atypical cells that we have to take more tissue and in that case we have to perform an excision biopsy the advantages are performing a fine needle or core biopsy is that there’s a very very small mark or an incision in the breast and so instead of having a large incision for an excisional biopsy there’s just a little punctate area on the breast that you will not really see over time In terms of any pain control,.
