-
Uncontrolled proliferation
Leukemic cells exhibit uncontrolled proliferation, dividing rapidly and excessively, leading to an accumulation of abnormal blood cells in the bone marrow and bloodstream.
-
Impaired differentiation
Leukemic cells fail to differentiate properly into mature, functional blood cells, resulting in a population of immature and non-functional cells that disrupt normal blood cell function.
-
Increased survival
Leukemic cells often have increased survival compared to normal blood cells, allowing them to accumulate and persist in the bone marrow and bloodstream.
-
Infiltration and metastasis
Leukemic cells can infiltrate and metastasize to other organs and tissues, leading to widespread damage and impairing overall health.
These facets of abnormal cell growth contribute to the malignant behavior of leukemia, highlighting the importance of understanding this aspect of the disease for developing effective treatments.

Disrupted Blood Cell Function
Disrupted blood cell function is a central component of leukemia's pathogenesis and a critical factor in defining leukemia as a cancer. The uncontrolled proliferation of abnormal blood cells in leukemia leads to a disruption in the normal production and function of healthy blood cells, resulting in a range of health problems.
One of the primary effects of disrupted blood cell function in leukemia is a decrease in the production of normal red blood cells. This can lead to anemia, a condition characterized by a deficiency of red blood cells or hemoglobin, the oxygen-carrying protein in red blood cells. Anemia can cause fatigue, weakness, shortness of breath, and pale skin.
In addition to anemia, disrupted blood cell function in leukemia can also lead to a decrease in the production of white blood cells. White blood cells are responsible for fighting infection, and a decrease in their production can make individuals more susceptible to infections. This can be a serious complication of leukemia, as infections can be life-threatening in individuals with a weakened immune system.
Finally, disrupted blood cell function in leukemia can also lead to a decrease in the production of platelets. Platelets are responsible for blood clotting, and a decrease in their production can lead to excessive bleeding. This can be a serious problem during surgery or other procedures that involve bleeding.
The disrupted blood cell function in leukemia highlights the critical role of healthy blood cells in maintaining overall health. The abnormal proliferation of leukemic cells disrupts this delicate balance, leading to a range of health problems that can be debilitating and even life-threatening.
