What causes leukemia?

Leukemia cause. We don't know for sure. Leukemia develops as the consequence of a series of genetic changes in blood cell offsprings. These changes alter normal growth and differentiation of the cells, resulting in an accumulation of abnormal, immature blood cells in the bone marrow and peripheral blood. Exposure to chemicals, radiation, tobacco, or chemotherapy, infection, etc have been associated with leukemia.
No one knows. There are associations like benzene but no known causative factors.

What causes leukemia? What is the treatment like? Is it a long term and continuous treatment? Is it going to cost a lot?

Depends. There are many types of leukemia and many types of treatment for each type. Some require just observation alone, otheres require aggressive, multiagency chemotherapy. Treatment can be quite expensive. Your best bet is an academic center that has extensive experience correctly diagnosing, treating and managing leukemia. Read more...
See below... Leukemia is multifactorial, being usually the consequence of genetic predisposition possibly combined with environmental factors. The treatment is complex and usually consists of chemotherapy with or without transplant, under the guidance of a hematologist/oncologist. The treatment is relatively long (months) but not continuous and some types can be cured. It is usually expensive. Read more...

What causes acute myelogenous leukemia?

DNA mutations. Leukemias occur due to mutations in dna. Many mutations have been linked to aml, however, the cause for most of the mutations remains unclear. Known risks include radiation exposure and certain chemical exposure. Read more...
Hard to say... Many times we don't know what causes leukemia, irrespective of type. The process is probably multifactorial and has a strong genetic component. In a small subset of cases exposure to various toxins like paint fumes, or to radiation, can also cause it, but this represents only a small percentage of patients. Read more...

In what way can chemicals cause leukemia?

Yes, sometimes. There are some chemicals that are known to cause bone marrow damage leading to acute leukemia. Most of these are chemotherapy drugs of the alkylating agents-class. Some petrochemicals like benzene are also implicated in some cases. Radiation from excessive exposure like from atomic bombs, or nuclear accidents are also known to cause it. Read more...
See below... Exposure to certain chemicals like benzene or formaldehyde may increase the risk for cancer including leukemia. This is probably due to the mutagenic effect of these agents, meaning they can induce mutations in otherwise normal cells resulting in abnormal cells that can become cancerous; however, the process is usually multifactorial and other conditions need to be met to develop cancer.

What external chemicals can cause leukemia and where are they found?

Benzene products. Benzene used in petrochemical industry is one know cancer causing agent. But most cases of leukemia come out of the blue, without any obvious or known cause. It is more of an accident of nature. I doubt you will be able to lay a finger on the cause of your leukemia. Read more...

What are the causes of leukemia in children?

Unknown. Most leukemias in adults and children do not have a specific etiology. Some leukemias in children can be linked to genetic abnormalities like down's syndrome, neurofibromatosis, bloom syndrome, and others. Ethnicity may play a role in all, hispanic children tend to have higer risk. High birth weight has been associated with higher risk though really this is unclear. Other factors are inconsistent.
