By Mayo Clinic staffBone marrow exams don't usually pose a big risk. Complications are rare, and those that do occur are often mild. They include:
- Excessive bleeding, particularly in people with a low platelet count
- Infection, especially in people with weakened immune systems
- Breaking of needles within the bone, which may cause infection or bleeding
- Long-lasting discomfort at the biopsy site
- Penetration of the breastbone (sternum) during sternal aspirations, which can cause heart or lung problems
- Complications related to sedation, such as an allergic reaction, nausea or irregular heartbeats
If you have a bleeding disorder, an infection at the planned biopsy site or had previous radiation treatments in that area, you may not be able to have a bone marrow exam.
