A bone marrow biopsy is the removal of marrow from inside the bone. Bone marrow is the soft tissue inside bones that helps form blood cells. It is found in the hollow part of most bones.

Bone marrow biopsy is not the same as bone marrow aspiration. An aspiration removes a small amount of marrow in liquid form for examination.

How the Test is Performed

A bone marrow biopsy may be done in the health care provider’s office or in a hospital. The sample may be taken from the pelvic or breast bone. Sometimes, another area is used.

Marrow is removed in the following steps:

  • If needed, you are given medicine to help you relax.
  • The provider cleans the skin and injects numbing medicine into the area and surface of the bone.
  • A biopsy needle is inserted into the bone. The center of the needle is removed and the hollowed needle is moved deeper into the bone. This captures a tiny sample, or core, of bone marrow within the needle.
  • The sample and needle are removed.
  • Pressure and then a bandage is applied to the skin.

A bone marrow aspiration may also be done, usually, before the biopsy is taken. After the skin is numbed, the needle is inserted into the bone, and a syringe is used to withdraw the liquid bone marrow. If this is done, the needle will be removed and repositioned. Or, another needle may be used for the biopsy.

How to Prepare for the Test

Tell the provider:

  • If you are allergic to any medicines
  • What medicines you are taking
  • If you have bleeding problems
  • If you are pregnant

How the Test will Feel

You will feel a sharp sting when the numbing medicine is injected. The biopsy needle may also cause a brief, usually dull, pain. Since the inside of the bone cannot be numbed, this test may cause some discomfort.

If a bone marrow aspiration is also done, you may feel a brief, sharp pain as the bone marrow liquid is removed.

Why the Test is Performed

Your provider may order this test if you have abnormal types or numbers of red or white blood cells or platelets on a complete blood count (CBC).

This test is used to diagnose leukemia, infections, some types of anemia, and other blood disorders. It may also be used to help determine if a cancer has spread or responded to treatment.

Normal Results

A normal result means the bone marrow contains the proper number and types of blood-forming (hematopoietic) cells, fat cells, and connective tissues.

What Abnormal Results Mean

Abnormal results may be due to cancers of the bone marrow (leukemia, lymphoma, multiple myeloma, or other cancers).

The results may detect the cause of anemia (too few red blood cells), abnormal white blood cells, or platelet count, which can increase bleeding risk. সহজ বাংলা: প্লাটিলেট কম।" data-rx-term="thrombocytopenia" data-rx-definition="Thrombocytopenia means low platelet count, which can increase bleeding risk. সহজ বাংলা: প্লাটিলেট কম।">thrombocytopenia (too few platelets).

Specific conditions for which the test may be performed:

  • A body-wide fungal infection (disseminated coccidioidomycosis)
  • A white blood cell cancer called hairy cell leukemia
  • Cancer of the lymph tissue ( Hodgkin or non-Hodgkin lymphoma )
  • Bone marrow doesn’t make enough blood cells ( aplastic anemia )
  • Blood cancer called multiple myeloma
  • Group of disorders in which not enough healthy blood cells are made (myelodysplastic syndrome; MDS)
  • A nerve tissue tumor called neuroblastoma
  • Bone marrow disease that leads to an abnormal increase in blood cells ( polycythemia vera )
  • Abnormal protein buildup in tissues and organs ( amyloidosis )
  • Bone marrow disorder in which the marrow is replaced by fibrous scar tissue ( myelofibrosis )
  • Bone marrow produces too many platelets ( thrombocythemia )
  • White blood cell cancer called Waldenström macroglobulinemia

Risks

There may be some bleeding at the puncture site. More serious risks, such as serious bleeding or infection, are very rare.

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Bone Marrow Biopsy – Indications, Procedure, Results

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
