What is the couse of leukemia?

Leukemia is a cancer of the blood and bone marrow. It starts when a white blood cell changes and begins to grow out of control. These abnormal cells can crowd out healthy blood cells, leading to anemia, infection, and bleeding.

There are many different types of leukemia, each with its own unique cause. Some of the most common causes of leukemia include:

* Genetic mutations: Some people are born with genetic mutations that increase their risk of developing leukemia. These mutations can be inherited from parents or they can occur spontaneously.

* Exposure to radiation: People who have been exposed to high levels of radiation, such as those who work with X-rays or nuclear materials, are at an increased risk of developing leukemia.

* Exposure to certain chemicals: Some chemicals, such as benzene, formaldehyde, and trichloroethylene, have been linked to an increased risk of leukemia.

* Viral infections: Some viruses, such as the Epstein-Barr virus and the human T-cell leukemia virus, can cause leukemia.

The exact cause of leukemia is often unknown. However, research is ongoing to identify the risk factors that can lead to this type of cancer.
