How Does Bone Marrow Affect Blood Cancer?

Author: Aarya Vibhandik

Abstract:

To begin, blood cancer is a disease that stems in the bone marrow or lymphatic system due to uncontrolled production of abnormal blood cells. Some of these blood cancers originate directly from bone marrow while others are indirectly affected by its blood cells. Bone marrow is a tissue which is located in the center of a bone and is the primary factory of producing blood cells. These immature blood cells crowd in the bone marrow leaving little to no space for healthy blood cells.

Types of Bone Marrow and their Functions

There are two types of bone marrow; red bone marrow and yellow bone marrow. Red bone marrow is responsible for creating red and white blood cells, platelets, as well as hematopoietic stem cells. Hematopoietic stem cells develop into these blood cells and platelets, creating every type of blood that your body needs. This bone marrow in adults is typically found in the hip bone, breast bone, and skull. Consequently, yellow bone marrow consists of mostly fat and stem cells that convert into fat, cartilage, or bone. Yellow bone marrow also has the ability to turn into red marrow if the body is in need of an immediate boost in blood cell production. 

Red blood cells, white blood cells, and platelets, are the main cellular components of the human blood. Red blood cells carry oxygen from the lungs to the rest of the body and return carbon dioxide. White blood cells defend the body by fighting off infections, viruses, germs, etc. Finally, platelets form blood clots to stop bleeding and to heal the wounds.

Development Blood Cancer In Bone Marrow:

Blood cancer develops in the bone marrow when genetic mutations in the DNA of blood forming cells form causing the cells to stunt maturity and uncontrollably multiply. Eventually, these immature cells start filling up space in the bone marrow crowding out the healthy blood cells and lead to cancer development.. Since the bone marrow is filled with cancerous cells it has no room to produce normal red, white blood cells, and platelets. This disrupted production of blood cells generates a low rate of vital blood components.

Types of Blood Cancer:

Due to this cultivation of abnormal and uncontrollably producing blood cells, cancers that develop are:

• Leukemia - This specific category of blood cancers derives directly from the bone marrow and from a mutation in the DNA that negatively affects how the blood cell divides and grows. DNA tells the blood cells when to grow and multiply. With leukemia, the DNA creates immature blood cells that multiply uncontrollably and don’t die. Subtypes include acute myeloid leukemia (AML) and Chronic Lymphocytic Leukemia (CLL).

• Multiple Myeloma - This cancer begins in the bone marrow’s plasma cells . Malignant plasma cells multiply and reside in the bone marrow developing multiple tumors that damage bones and crowd out healthy cells.

• Lymphoma - This type of blood cancer originates in the lymphatic system (lymph nodes and vessels) over the bone marrow. However, later stages can spread to the bone marrow causing a downfall in blood cell production.

• Myelodysplastic Syndrome (MDS) - This disorder originates in the stem cells of the bone marrow. MDS causes inaccurate production in the bone marrow to produce faulty cells.

  

Conclusion:

In conclusion, bone marrow does not simply “cause” blood cancer. Instead, many blood cancers originate from or are significantly affected by the  blood forming cells of the bone marrow. Hence, when abnormal cells replace and interfere with healthy bone marrow cells, the body's ability to produce red blood cells, white blood cells, and platelets can be negatively disrupted resulting in blood cancer.
