Chronic Myeloid Leukemia

Hodgkin's Lymphoma

Non-Hodgkin's lymphoma

M4 Acute Myelomonoblastic Leukemia

M4 Acute Myelomonoblastic Leukemia is a type of acute myeloid leukemia characterized by the proliferation of myeloblasts and monoblasts.

7. What does M6 Acute Erythroleukemia represent?

Multiple Myeloma

Hodgkin Lymphoma

M6 Acute Erythroleukemia

Chronic Myeloid Leukemia

M6 Acute Erythroleukemia is a specific type of leukemia characterized by the proliferation of erythroblasts in the bone marrow.

Explanation

M6 Acute Erythroleukemia is a specific type of leukemia characterized by the proliferation of erythroblasts in the bone marrow.

8. What is M7 Acute Megakaryocytic Leukemia representative of?

Genetic disorder causing sickle cell anemia

M7 Acute Megakaryocytic Leukemia

Bacterial infection causing pneumonia

Viral infection leading to hepatitis

M7 Acute Megakaryocytic Leukemia is a specific subtype of leukemia that involves abnormal growth of megakaryocytes, which are cells responsible for producing platelets. It is not caused by bacterial infection, genetic disorders like sickle cell anemia, or viral infections like hepatitis.

Explanation

M7 Acute Megakaryocytic Leukemia is a specific subtype of leukemia that involves abnormal growth of megakaryocytes, which are cells responsible for producing platelets. It is not caused by bacterial infection, genetic disorders like sickle cell anemia, or viral infections like hepatitis.

9. What is M5 Acute Monocytic Leukemia representative of?

Lung infection

Breast cancer

M5 Acute Monocytic Leukemia (giemsa stain)

Alzheimer's disease

M5 Acute Monocytic Leukemia is a type of leukemia characterized by an abnormal increase of monocytes in the bone marrow and blood. The giemsa stain is used to differentiate between different types of white blood cells.

Explanation

M5 Acute Monocytic Leukemia is a type of leukemia characterized by an abnormal increase of monocytes in the bone marrow and blood. The giemsa stain is used to differentiate between different types of white blood cells.

10. What is L3 Acute Lymphoblastic Leukemia representative of?

Prostate Cancer

L3 Acute Lymphoblastic Leukemia (3-5% ALL cases, rare, large cells, midnight blue) - AKA Burkitt's Lymphoma

Hodgkin's Lymphoma

Lung Cancer

L3 Acute Lymphoblastic Leukemia is a type of leukemia characterized by large cells with a midnight blue appearance, it is also known as Burkitt's Lymphoma. It is not associated with Lung Cancer, Hodgkin's Lymphoma, or Prostate Cancer.
