Chronic myeloid leukemia (CML) is a type of cancer that begins in the bone marrow and affects the body's production of white blood cells. It is caused by a genetic mutation in the bone marrow cells, which causes them to grow and divide uncontrollably. The exact cause of this mutation is unknown, but it is believed to be caused by exposure to certain environmental factors or by inherited genetic mutations.
What Causes CML?
The exact cause of CML is unknown, but it is believed to be caused by a combination of environmental and genetic factors. Exposure to radiation, certain chemicals, or certain viruses have all been linked to an increased risk of CML. Inherited genetic mutations, such as those in the BCR-ABL gene, are also believed to be a cause of CML.
What Are the Symptoms of CML?
Early symptoms of CML can include fatigue, weight loss, fever, night sweats, and an enlarged spleen. As the disease progresses, more serious symptoms may develop, including anemia, bruising, bleeding, and a weakened immune system.
How Is CML Diagnosed?
CML is diagnosed through a combination of blood tests, bone marrow biopsies, and genetic testing. Blood tests can detect an elevated level of white blood cells, which is a sign of CML. A bone marrow biopsy can confirm the diagnosis, as it can detect the presence of the BCR-ABL gene, which is associated with the disease. Genetic testing can also be used to confirm the diagnosis.
How Is CML Treated?
Treatment for CML typically involves medications that target the BCR-ABL gene. These medications can slow or stop the growth of cancer cells and help control the symptoms of CML. In some cases, a stem cell transplant may be recommended to replace the damaged bone marrow cells. Surgery may also be used to remove the spleen if it is enlarged.
What Is the Prognosis for CML?
The prognosis for CML depends on a variety of factors, including the stage of the disease and the response to treatment. In general, the outlook is good if the disease is detected and treated early. With proper treatment, the majority of people with CML can expect to have a normal life expectancy.
