Everything you want to know about a Bone Marrow Biopsy!
When your doctor tells you that you need to have a bone marrow biopsy, you might be a little nervous and curious, right? You might have a lot of questions like, "What is it? Why is it being done? Will it hurt?" Don't worry, in this article we'll talk about it all in a simple way that you can understand.

What is a Bone Marrow Biopsy?

Simply put, a bone marrow biopsy is a special test that is done to diagnose diseases related to your blood and bone marrow. Did you know that the bone marrow is the main place in our body where blood is made. It's like a factory. In this test, your doctor removes a small sample, or part, of this bone marrow from inside one of your large bones. Then, a specialist doctor called a pathologist looks at this sample under a microscope and checks for signs of any disease. This bone marrow biopsy is essential to accurately diagnose many diseases, especially blood-related diseases and some types of cancer.

So, what is this bone marrow?

Imagine, inside the large bones in our body, there is an empty space, like the inside of a tube. Inside that empty space is what is called the ``Bone Marrow``. It consists of two parts: a soft, spongy tissue part, and a liquid part. This tissue part in the bone marrow is what makes three things that are essential for our body:
  • Red blood cells : These are the cells that carry oxygen throughout our bodies. When we breathe, the oxygen that enters the lungs is distributed to every cell in the body by these red blood cells.
  • White blood cells : Like our body's defense forces, these white blood cells protect us from germs and infections.
  • Platelets: Do you know how you stop bleeding when you get hurt? These platelets help with that. When a blood vessel is broken, they clump together to form a clot and stop the bleeding .
The liquid part of the bone marrow contains stem cells , that is, cells that are not yet mature but can become red blood cells, white blood cells, and platelets. Also, the vitamins needed for the development of these cells are produced in this liquid part. Now you probably understand that a bone marrow biopsy examines this part of the tissue. However, there is another test called a bone marrow aspiration , which examines that liquid part. Most of the time, your doctor will do this aspiration at the same time as the biopsy.

At what point does a doctor recommend a bone marrow biopsy?

A bone marrow biopsy can provide doctors with a lot of valuable information. They use that information to:
  • To assess or diagnose a medical condition: For example, if you see an abnormal change in the number of blood cells in a blood sample (either too low or too high), your doctor may recommend a biopsy. This can help diagnose many things, including blood-related diseases, cancer, unexplained fevers, and infections.
  • If you have cancer, determine its stage: The stage of a cancer is how far it has spread and how severe it is. A bone marrow biopsy can tell if the cancer has spread to the bone marrow or if a cancerous tumor in the bone marrow is growing.
  • Monitor the progress of treatment: Sometimes, doctors also do this biopsy to see how well the treatment is working. For example, a person undergoing treatment for cancer may have this test done periodically to see if their bone marrow is producing healthy blood cells after treatment.
Another thing is that this biopsy is also used to see if a donor is a good match for someone who is going to have a bone marrow transplant (allogeneic stem cell transplant ). Sometimes, a person with low levels of healthy blood cells needs to have healthy stem cells transplanted from someone else. For that to happen, the cells of the donor and the recipient must match.

What diseases can be detected with a bone marrow biopsy?

This biopsy is usually done to diagnose conditions that cause too many or too few blood cells. It is also used to diagnose cancers that affect your blood or bone marrow. Here are some of the conditions that can cause this:
  • Anemia: A lack of enough red blood cells to carry oxygen throughout the body. We also call it " anemia ."
  • Aplastic anemia: A condition in which the bone marrow is unable to produce enough red blood cells, white blood cells, and platelets.
  • Leukopenia and leukocytosis: A very low (leukopenia) or very high (leukocytosis) white blood cell count.
  • Thrombocytopenia and thrombocytosis: A very low (thrombocytopenia) or very high (thrombocytosis) platelet count.
  • Polycythemia vera: This is a rare blood cancer in which the bone marrow produces too many red blood cells.
  • Leukemia: A cancer of the blood cells. It can cause abnormal blood cells, especially white blood cells, to form.
  • Lymphoma:A cancer that develops in the lymphatic system. This can also cause abnormalities in the white and red blood cell counts.
  • Multiple myeloma: This is also a rare blood cancer. It affects plasma cells, a type of white blood cell.
  • Secondary cancers: Cancers that start elsewhere in the body (e.g., breast, lung) and then spread to a second site, such as the bone marrow.
  • Myelofibrosis: In this condition, the bone marrow is replaced by fibrous scar tissue.
  • Myelodysplastic syndrome: This is a bone marrow disorder in which stem cells do not mature properly.
In addition, this biopsy can also help identify chromosome abnormalities and certain vitamin deficiencies. These deficiencies can cause the bone marrow to produce abnormally shaped or larger red blood cells.

Who is doing this biopsy?

This bone marrow biopsy is usually performed by a doctor who specializes in blood-related diseases (hematologist) or a doctor who specializes in cancer (oncologist) .

How do you prepare for this? What do you need to do?

Your doctor will explain the test to you and give you instructions on how to prepare. For example, if you are given a sedative to help you sleep on the day of the test, you may be asked to fast the night before the test. If this is the case, you will need to arrange for someone to drive you home. Your doctor will need to know your complete medical history and any medications you are currently taking. So, be sure to tell them about:
  • Do you have a condition that prevents your blood from clotting easily (such as hemophilia)?
  • Are you taking any medications (especially anticoagulants or blood thinners)?
  • Do you take any vitamins or supplements?
  • Do you have any allergies to any medications?
Also, if you are pregnant, you should let the doctor know. By telling them all this in advance, the medical team can help you have this test safely and comfortably.

What to expect when having a biopsy?

A bone marrow biopsy can be done in a doctor's office or in a hospital. The entire procedure takes about 30 minutes.You will be awake during the test, but you will be given local anesthesia to help you feel comfortable. Before the test, you will be given a hospital gown. You may also be given a sedative to help you relax. The steps usually go like this: 1. Depending on where the biopsy is being done, you will be turned onto your side or stomach. Most bone marrow biopsies are done on the back of your hip bone (posterior iliac crest) . 2. Then, your doctor will clean the skin in the area with an antiseptic and inject a numbing medication through the skin until it reaches the bone. 3. They will make a small incision and insert a special biopsy needle into your bone. 4. Using a small syringe attached to the needle, a small amount of fluid is removed from your bone marrow ( the bone marrow aspiration we talked about earlier). 5. Then, a hollow, tube-like needle is inserted and a small piece of the spongy tissue in the bone marrow is removed. This is called a core biopsy . This is because a cylindrical "core" of tissue is removed from the needle. 6. The needle containing the sample is removed, pressure is applied to the skin to stop the bleeding, and a bandage is placed over the wound. The doctor then sends the sample to a lab. There, it is tested for signs of disease.

Does this hurt?

This is a question that many people ask. To be honest, it can be a little uncomfortable. When you do the bone marrow aspiration, which is when the liquid part is taken, you may feel a sharp stabbing pain . When you do the core biopsy, which is when the tissue part is taken, you may feel a dull, aching pain for a while . Unfortunately, the bone cannot be numbed. So, you may feel things like pressing, pushing, pulling, which is a little uncomfortable.
But don't worry. If you have any concerns or questions about the pain, talk to your doctor. They can give you medication to help you feel more comfortable, in addition to numbing the area where the biopsy is being done.

What happens after the biopsy?

You can usually go home the same day as the test. However, if you were given a sedative, you will need someone to drive you home. Once you go home, you should follow your doctor's instructions exactly. They may say things like:
  • If you have any pain or discomfort, take a nonprescription pain reliever that you can get from the pharmacy without a doctor's prescription.
  • Avoid exercising or doing heavy work for at least 24 hours.
  • Keep the wound area dry for at least 24 hours.

Are there any risks in this?

In fact, complications from a bone marrow biopsy are very rare.However, rarely, there may be excessive bleeding or infection at the biopsy site. Usually, applying pressure to the area will stop the bleeding. If an infection occurs, your doctor may give you an antibiotic cream to apply.

What are the results? What do they tell us?

Your bone marrow sample is examined under a microscope by a specialist called a pathologist . When your doctor gets his or her findings, he or she will discuss them with you and tell you what to do next. Depending on your results, your doctor may confirm a diagnosis, order more tests, or recommend treatment, or make changes to your current treatment. The most important thing is to ask your doctor what your results mean to you. Because everyone's situation is different, your doctor is the best person to know exactly what your results mean.

When should you see a doctor quickly?

If you develop any symptoms of complications after the test, see your doctor immediately. Such symptoms include:
  • If there is excessive bleeding or fluid oozing from the biopsy site.
  • If there is swelling where the biopsy was done.
  • The area is red (especially if the redness spreads).
  • If you get a fever or the pain gets worse .

Finally, things to remember (Take-Home Message)

If you have symptoms of a blood disease or other condition that affects the bone marrow, it is common to have a bone marrow biopsy. If you have any specific questions about this test or are worried about the sensations during the biopsy, talk to your doctor. They can give you painkillers to help you feel comfortable and relaxed. They can also explain each step of the test to you. This will help you feel more informed and confident when you have your biopsy. Taking care of your health is the most important thing, so don't be afraid to seek medical advice.
