The patient may experience a stinging sensation when the needle is inserted. Although the patient may feel some discomfort when the marrow sample is taken, the procedure is relatively quick.

Bone marrow biopsies are performed if blood tests indicate an abnormality or if the doctor needs to form a diagnosis, explains Mayo Clinic. The results from the procedure can also show iron levels or medical conditions associated with blood problems, such as leukopenia.

Risks depend on individual tolerances and health history.Learn more about Diagnostics & Imaging
