Is leukemia a hereditary disease?

Genetic factors play a significant role in the development of leukemia. Research indicates a strong association between leukemia and inherited genetic predispositions. If a family member has had leukemia, certain susceptibility genes may be passed down, increasing the likelihood of chromosomal abnormalities within the body that could trigger leukemia. Exposure to chemical pollutants—particularly benzene and its derivatives found in industrial chemicals—is another major cause of leukemia. Individuals involved in home renovation or working in leather manufacturing are at notably higher risk for developing leukemia. In daily life, minimizing exposure to toxic chemicals is strongly advised.

Ionizing radiation is also a known risk factor for leukemia. Certain types of radiation can induce genetic alterations in human cells, potentially leading to leukemia. Even some routine medical imaging procedures involving ionizing radiation—such as repeated X-rays or CT scans—may increase leukemia risk if performed excessively.

Additionally, certain oncogenic viruses—such as retroviruses—can cause leukemia in mammals and may also trigger leukemia in humans upon infection. Once inside the human body, these viruses can disrupt normal gene function. While genetic predisposition cannot be prevented, many other risk factors for leukemia can be effectively mitigated through preventive measures. If there is a family history of leukemia, regular health check-ups are recommended. We hope this article has been helpful to you. Wishing you a joyful life and good health!
