This biopsy procedure is done to make a proper diagnosis of suspected breast cancer. Core Needle Biopsy is highly preferred by doctors because it is a non-surgical procedure that allows to extract and examine more breast tissue. During the procedure, the person is given local anaesthesia to numb a particular area of the breast. A hollow needle attached to a spring-loaded tool is used to remove a core of the breast tissue.
- The suspected area is numbed with the help of an anaesthetic that is injected through a needle.
- A small incision is made on the breast, and a needle is inserted through the opening.
- Once the tissue is extracted, the needle is removed, and the opening is covered with a sterile dressing.
- A nurse may apply pressure on the opening for a short period of time to help control the bleeding.
- A pathologist will examine the biopsy tissue or the extracted fluid to ascertain the presence of cancer cells.
- A second biopsy may be suggested if the first one is not clear or if the doctor feels the need for further evaluation.
The FNA is a fairly quick procedure which does not involve any incisions, stitches or scars. The entire procedure takes about 20 to 30 minutes. During the process, a fine needle is used to extract tissues or fluids from the suspicious area. The sample is then thoroughly examined for cancer cells.
- The procedure starts with the person lying on his/her back, and the doctor uses an anaesthetic to numb the affected area.
- The person lies still while the physician inserts a fine needle into the suspected area and extracts tissues or fluid.
- The doctor may repeat the procedure a number of times to ensure the proper extraction of the sample.
- Once the biopsy is complete, the area is thoroughly wiped and covered with a sterile dressing or bandage.
- A pathologist will check the extracted tissue or fluid for cancer cells.
- The fluid is checked for its colour to ascertain if it is clear or bloody.
- The doctor will further look for a smaller group of cells to make further examinations.
