There are 2 methods used to obtain the sample. One is a needle biopsy
, and the other is called an open biopsy. NEEDLE biopsy
You undress to the waist and sit or recline. The injection site is cleaned and sterilized, then injected with a local anesthetic. A needle attached to a syringe is then introduced into the lesion or lump to be studied. Fluid may be removed first, then a tissue sample is obtained. The fluid is stored in a special tube, and the tissue sample is placed in a specimen bottle with preservative. Once the tissue sample has been taken, the needle is removed, and pressure is applied to the site to stop any bleeding
. A bandage will be applied to absorb any fluid. OPEN biopsy
This method is also called a lumpectomy
. You undress to the waist and sit or recline. A local or general anesthetic is administered (depending on the size of the mass and your condition), and an incision is made to expose the lump. The entire mass may be removed if it is not too big, or part may be excised (removed) if the lump is larger. The tissue may be tested before the entire lump is removed. After the tissue sample is taken, the incision is sutured, and a dressing and bandage are applied. If general anesthesia is administered, vital signs
, rate of breathing, blood pressure
) will be monitored for at least 1 hour after completion of the procedure. Pain medication may be prescribed.
