How do people get luekemia?

Leukemia is a type of cancer that affects the blood and bone marrow, and its exact causes remain largely unknown. However, several risk factors have been identified, including genetic predispositions, exposure to certain chemicals (like benzene), previous radiation exposure, and specific viral infections. While it is not contagious and cannot be directly transmitted from person to person, a combination of genetic and environmental factors may contribute to its development.
