- Is a Needle Stick Biopsy a Reliable Test?
-
-
- ------------------------------------------------------------------------------

- QUESTION: When my sister told me she was to have a biopsy of a lump in her
- breast, we spent many hours discussing this procedure. When she finally went
- to the doctor, all he did was stick a needle in her breast instead of cutting
- out a piece of tissue as you had mentioned in your column. She has now been
- told that everything is all right with nothing to worry about. Is this a
- reliable test, and can we both stop worrying now?

- ANSWER: A skillfully performed fine needle aspiration biopsy can often be an
- accurate, efficient and cost effective method for evaluating a breast lump and
- obtaining a diagnosis. Rather than cutting out tissue for examination under
- the microscope, the cells are sucked out or "aspirated" through the needle,
- and these cells can be stained and microscopically examined as any other
- tissues. The technique was first made popular back in the 1930's at the
- Sloan-Kettering Cancer Center in New York City, but declined in usage over the
- following years. However, when the procedure was perfected and refined in
- Europe during the 50's and 60's it once again became a widely used technique.
- It is now used to evaluate many types of lumps and bumps, such as thyroid
- masses and enlarged lymph glands, as well as to obtain cells and tissues from
- the lung, liver, pancreas, kidney, and prostate. It may serve as an important
- first step in establishing a diagnosis, determining whether or not a mass is a
- malignant tumor or merely a benign mass. In the case of cysts (fluid filled
- masses), it may even serve as a treatment by removing the liquid from the
- cyst. In most cases it is a relatively painless procedure, and is inexpensive
- as well, with average costs running from $75 to $100. The rate of false
- positives for a fine needle aspiration biopsy of a breast mass runs from 0
- percent to 4.1 percent, but the false negatives may run much higher, as great
- as 31 percent according to some studies. However, the results must be
- interpreted in light of the physical examination, history and other tests that
- may have been performed. I am sure that if the physician had any doubts about
- the reliability of the results, he would have requested an additional test,
- perhaps even an open biopsy, where the tissue is cut away. From the details
- in your letter, I believe that both you and your sister can be reassured and
- stop worrying now.
