Bone Marrow Biopsy
Biopsia de médula ósea
What it means
A bone marrow biopsy is the removal of marrow from inside a bone. Bone marrow is the soft tissue inside bones that helps form blood cells. The National Cancer Institute dictionary describes the procedure: a small sample of bone with bone marrow inside it is removed, usually from the hip bone, after a small area of skin and the surface of the bone underneath are numbed with an anesthetic, and the sample is sent to a laboratory to be looked at under a microscope. MedlinePlus says the test is used to diagnose some types of anemia, certain infections, leukemia, and other blood cancers and disorders. A bone marrow biopsy is not the same as a bone marrow aspiration, which removes a small amount of marrow in liquid form.

Biopsia de médula ósea is the title and the wording of the MedlinePlus en español encyclopedia article, and the noun is feminine: una biopsia de médula ósea. The National Cancer Institute's Spanish dictionary enters the same procedure with the article: biopsia de la médula ósea. The related procedure is aspiración de médula ósea on MedlinePlus en español and aspiración de la médula ósea in the NCI dictionary.
Where the English page says the sample is usually taken from the pelvic bone, MedlinePlus en español writes el hueso de la pelvis; the NCI dictionary says el hueso de la cadera (hip bone). Words for the procedure are aguja (needle), jeringa (syringe), anestésico (numbing medicine), muestra (sample) and vendaje (bandage). The blood count that may lead to the test is conteo sanguíneo completo (CSC), and the cells it counts are glóbulos rojos, glóbulos blancos and plaquetas. MedlinePlus en español describes the feeling of the injection as una punzada aguda, where the English page says a sharp sting.
