1. Acute Myeloid Leukemia:

Acute Myeloid Leukemia, commonly referred to as AML, is a type of cancer that affects the bone marrow and blood. It is characterized by the rapid growth of abnormal myeloid cells, which are the precursors of mature blood cells. In AML, these abnormal cells accumulate in the bone marrow, disrupting the production of normal blood cells.

2. Myeloid Cells:

Myeloid cells are a crucial component of the body's immune system responsible for fighting infections and maintaining the body's defense mechanisms. These cells differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets.

3. Leukemia:

Leukemia is a type of cancer that originates in the blood-forming tissues of the body, particularly the bone marrow and lymphatic system. It results in the uncontrolled production of abnormal blood cells, which interfere with the normal functioning of the immune system.

4. Bone Marrow:

The bone marrow is a spongy tissue found within the bones, primarily responsible for the production of blood cells. It houses stem cells that give rise to red blood cells, white blood cells, and platelets.

5. Blood Cells:

Blood cells encompass red blood cells, white blood cells, and platelets, each with distinct functions vital for maintaining overall health and bodily functions.

6. Stem Cells:

Stem cells are undifferentiated cells capable of developing into various specialized cell types. In the context of AML, abnormal stem cells give rise to leukemic myeloid cells, leading to the disruption of normal blood cell production.

7. Mutation:

Mutations refer to alterations in the genetic material of cells, leading to changes in the functioning of these cells. In the context of AML, mutations in the genetic makeup of myeloid cells contribute to the development and progression of the disease.
