How does leukemia affect the cells?

Leukemia affects the cells by causing the bone marrow to produce an excessive number of abnormal white blood cells. These dysfunctional cells do not effectively fight infections and can crowd out healthy blood cells, leading to anemia, increased bleeding, and a weakened immune system. As leukemia progresses, it can infiltrate other organs and tissues, disrupting normal bodily functions. Ultimately, this abnormal cell proliferation can significantly impair overall health and well-being.
