While this disease is linked to changes in genetic material (DNA) within bone marrow cells, these changes are typically acquired during an individual's lifetime and are not inherited at birth. The precise reasons behind these genetic changes remain unknown in most cases [\[1\]](). ## The Nature of Genetic Changes in Leukemia Leukemia is an umbrella term for cancers of the blood cells that start in the blood-forming tissues, specifically in the bone marrow. The bone marrow is responsible for producing stem cells that later develop into white blood cells (to fight infection), red blood cells (to carry oxygen), or platelets (to help with blood clotting). In the case of leukemia, mutations or changes occur in the DNA of stem cells, leading to the production of large numbers of abnormal cells that accumulate in the blood and bone marrow and crowd out healthy cells, hindering the body's ability to perform its vital functions normally [\[1\]](). ## Risk Factors and Aging Although leukemia is not inherited, there are other factors that increase the chances of developing it. Studies have proven that the risk of leukemia increases with age, as cases are more common among people over sixty [\[1\]](). In addition to age, environmental and health factors play a role in increasing the likelihood of infection, as these factors can lead to the accumulation of damage or changes in bone marrow cells over time. ## The Importance of Early Diagnosis and Clinical Verification Since the root causes of the disease are not simple hereditary ones, diagnosis depends primarily on precise medical tools to assess the condition of the bone marrow and blood. Diagnostic steps usually include a comprehensive physical examination, a review of medical history, and specialized blood tests such as a Complete Blood Count (CBC), which measures the levels of different blood cells [\[2\]](). If doctors suspect an abnormality, they will resort to bone marrow tests, which include drawing a fluid sample or performing a bone biopsy to analyze it in the laboratory for the presence of abnormal cells or chromosomal changes [\[1\]](). ## Signs Requiring Medical Consultation Symptoms that may indicate problems in the bone marrow should not be ignored, as medical intervention is required to evaluate the condition. Symptoms that warrant a medical examination include: persistent fatigue, unexplained weight loss, fever, night sweats, easy bleeding or bruising, and the appearance of small red spots under the skin known as petechiae [\[1\]](). If you would like to know more about the path of dealing with the disease and the available options, you can read our article on [leukemia types, symptoms, and treatments (Arabic)](). Always remember that early diagnosis depends on precise laboratory tests, not on individual genetic guesses. ## Medical references - [Leukemia]() - [Blood Tests Blood Tests]() General health education; not a substitute for individualized clinical assessment.
