Understanding the 10 Major Variants of Leukemia

Leukemia is a cancer that impacts blood and bone marrow cells. It begins when abnormal blood cells, often in the marrow, grow uncontrollably, hindering normal function. The disease’s progression depends on how quickly leukemic cells replace healthy blood components. Here, we explore the ten primary types of leukemia, categorized by cell origin and growth pattern.

Acute Lymphoblastic Leukemia (ALL)
This rapidly progressing cancer originates from lymphoid stem cells in the bone marrow and may spread to the central nervous system, lymph nodes, or testes.

Acute Myeloid Leukemia (AML)
Developing from mutations in myeloid cells, AML affects red cells, white cells, and platelets, often resulting in pancytopenia.

Chronic Lymphocytic Leukemia (CLL)
A slow-growing disease primarily affecting older adults, CLL involves accumulation of abnormal lymphocytes, often without symptoms for years. Studies link CLL to herbicides like Agent Orange.

Hairy Cell Leukemia (HCL)
A rare malignancy marked by unique hair-like projections on affected B lymphocytes, HCL impacts bone marrow, liver, and spleen but generally allows for good quality of life with treatment.

Chronic Myelomonocytic Leukemia (CMML)
An uncommon form affecting stem cells and monocytes, CMML compromises immunity and can cause bleeding due to decreased platelets.

Juvenile Myelomonocytic Leukemia (JMML)
Usually diagnosed in children under five, JMML involves uncontrolled monocyte growth, reducing immune defenses and causing anemia and bleeding issues.

Large Granular Lymphocytic Leukemia (LGL)
Affecting lymphocytes, LGL is a chronic leukemia seen in middle-aged adults, characterized by enlarged spleen and liver, with T-cell and NK-cell subtypes.

Blastic Plasmacytoid Dendritic Cell Neoplasm
Recognized by WHO as related to AML, this rare leukemia affects white blood cells, spleen, and platelets, sometimes involving lymph nodes without clear symptoms.

B-cell Prolymphocytic Leukemia (B-PLL)
An aggressive B-cell cancer typically diagnosed around age 70, B-PLL results from overgrowth of lymphocytes, presenting with spleen enlargement, anemia, and low platelets.

T-cell Prolymphocytic Leukemia (T-PLL)
An extremely rare and aggressive leukemia affecting T-lymphocytes, primarily in older men, often caused by chromosomal abnormalities, leading to multi-organ enlargement if untreated.
