Bone marrow exams are safe procedures. Complications are rare but can include:

  • Excessive bleeding, particularly in people with a low platelet count
  • Infection, especially in people with weakened immune systems
  • 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
