What Are The Causes Of Cll

Chronic lymphocytic leukemia, or CLL, is a cancer that occurs in a patient's bone marrow and blood. CLL affects white blood cells known as the lymphocytes. This disease often progresses at a slower pace than other types of leukemia.








Genetic Mutation


According to the Mayo Clinic, CLL occurs when genetic mutations in the bone marrow cause abnormal lymphocytes to be created that are not effective at fighting infections.


Family History


Individuals with a family history of CLL may be at a greater risk of developing the disease.








Chemicals


Exposure to Agent Orange and other insecticides or herbicides increases the likelihood of developing CLL.


Demographics


Men and people over the age of 50 have a higher risk of getting chronic lymphocytic leukemia. Whites have a higher likelihood of developing CLL than people of other races.


Symptoms


CLL may develop without symptoms or it may cause painless enlarged lymph nodes, fever and fatigue. Frequent infections, night sweats and weight loss may also occur.
