LEUKAEMIA CAUSES |
|
|
|
The cause of leukaemia is unknown. However, a number of factors may
be involved.
Genetic factors
Patients with CML have an abnormal chromosome called the
Philadelphia chromosome. This is also found in some cases of chronic
B lymphocytic leukaemia.
People who have Downs
syndrome, or a condition called Fanconi's anaemia, have an increased
risk of acute leukaemia.
Radiation
Exposure to excess levels of ionising radiation increases the risk
of developing acute leukaemia. People who are treated with
chemotherapy and radiation for other cancers also have an increased
risk.
Drugs and
chemicals
Chemotherapeutic drugs, drugs that suppress the immune system and
chloramphenicol (an antibiotic used to treat bacterial eye
infections) increase the risk. So do organic chemicals such as
benzene and its derivatives. |
