FNABs allow your physician to determine the cause of an abnormal lump, mass or lesion, allowing for appropriate treatments to be planned. This is a type of biopsy in which a very thin needle is used to withdraw small fragments of tissue from the tumor mass or lump.
The procedure is performed under local anesthetic to alleviate any discomforts felt during the biopsy. Once the mass is located (usually by x-ray) a very fine needle is inserted into the mass to withdraw cells from the suspicious area. It is not abnormal for multiple needles to be inserted, this allows for biopsies of all areas of the mass.
This procedure takes somewhere between 30 and 60 minutes and carries with it only minor risks. You will be asked to arrive at the hospital two (2) hours prior to your biopsy and should expect to stay for approximately 2-3 hours post biopsy.
Before the Procedure
All FNABs are conducted at Southlake Regional Health Centre; the procedure itself takes about 30 to 60mins. You will need to register at the Welcome Centre at the hospital at least half an hour before your scheduled operation.
