When the indicators of breast examinations suggest abnormalities, your doctor suggests that you need a biopsy to make a definite diagnosis. A biopsy means removing one or several strips of tissue from the diseased area of the breast, and then observing the morphology of cells and other microstructures under a microscope. Of course not every woman who has a biopsy has cancer. If the pathologist finds cancer cells, the doctor will follow the type of tissue to develop a treatment plan or decide if more tissue removal is necessary. The type of biopsy is usually determined by the size of the abnormal area of the breast as well as the mammogram, ultrasound and other tests to determine the type of biopsy. There are several types: 1) fine needle aspiration cell biopsy; 2) tissue biopsy, also called vacuum-assisted tissue biopsy; 3) stereotactic tissue biopsy; and 4) surgical incision or excisional biopsy. Details are as follows: 1, fine needle aspiration cell biopsy, the doctor uses a fine needle with a hole to remove cells from the abnormal area, through the operation can be done in the office, the patient needs to lie down, under local anesthesia, and will not leave a scar after the operation. In exceptional cases, imaging instruments such as ultrasound may be required to locate the lesion. 2.Tissue biopsy or vacuum-assisted biopsy, using a needle with a larger hole to remove several strips of tissue from the breast lesion area (usually three strips, more may be taken if there is a special need), and in special cases, imaging instruments such as ultrasound may be required to locate the lesion. In some cases, the doctor needs to use special photographic equipment to guide the biopsy. Usually, you need to take a face-down position and place the breast inside a special device, and the doctor will find the lesion and take the tissue according to this photographic equipment. Vacuum-assisted tissue biopsy or stereotactic tissue biopsy can be performed under ultrasound or MRI guidance with local anesthesia, and the doctor will usually place small fragments in the breast after the procedure to mark the location of the biopsy. This will provide a great deal of help in case further biopsy or surgery is needed. This procedure will not produce scars in most women. 4. Surgical biopsy, if the doctor needs more information and a fine needle or tissue biopsy does not suffice, he will opt for a surgical biopsy. A surgical biopsy is also called an incisional or excisional biopsy, depending on how much breast tissue needs to be taken from the suspected area. This type of biopsy usually requires only local anesthesia, not general anesthesia. Because the surgeon uses a scalpel to cut open the breast to remove the abnormal tissue, it may be sutured. This operation may result in scarring and generally requires two or three weeks to recover.
