Introduction
Leukemia is not an inherited disease. It is currently considered to result from acquired genetic mutations that disrupt the production and differentiation of white blood cells, leading to their accumulation at primitive or immature stages and subsequent damage to tissues and organs. However, these mutations are not inherited from parents but occur as somatic mutations later in life. Additionally, an individual’s underlying genetic background—particularly certain genetic predispositions—may also play a role.
Currently, leukemia appears to be increasingly prevalent among children—a noticeable trend that raises the question: Is leukemia a hereditary disease?
Is Leukemia a Hereditary Disease?
Leukemia is not a hereditary disease. It is now understood to result from acquired genetic mutations that disrupt the production and differentiation of white blood cells, leading to the accumulation of immature or blast cells and subsequent damage to tissues and organs. Importantly, these mutations occur in somatic (non-germline) cells—not inherited from parents. However, an individual’s underlying genetic background may confer susceptibility; while leukemia is not a congenital disorder, certain pre-existing genetic variations or functional deficiencies may increase an individual’s risk of developing leukemia-associated mutations.
Leukemia treatment is comprehensive, encompassing infection prevention, supportive care, immunotherapy, radiation therapy, traditional Chinese medicine, nursing, and other modalities. Chemotherapy remains the primary treatment for childhood leukemia. The majority of pediatric patients achieve cure with chemotherapy alone; only a small subset with suboptimal response requires hematopoietic stem cell transplantation following chemotherapy.
With standardized treatment, over 90% of children with leukemia attain complete remission. Although bone marrow transplantation was once considered the sole curative option, finding a suitable donor remains challenging. Fortunately, most children with leukemia do not require bone marrow transplantation. We hope this information has been helpful.
