Genetics/Leukemia - Blood Cancer.

The exact cause of leukemia is not known, but it is thought to involve a combination of genetic and environmental factors. Leukemia cells have acquired mutations in their DNA that cause them to grow abnormally and lose functions of typical white blood cells.

It is not clear what causes these mutations to occur. One type of change in the cells' DNA that is common in leukemias is known as a chromosome translocation. In this process, a portion of one chromosome breaks off and attaches to a different chromosome. One translocation seen in almost all cases of CML and in sometimes in other types of leukemia is an exchange of DNA between chromosomes 9 and 22, which leads to what is known as the Philadelphia chromosome. This creates an oncogene (cancer-promoting gene) known as BCR-ABL. This change in DNA is not inherited but occurs sometime in the life of the affected individual. That's why researchers keep studying about Leukemia cells through commercial resource(eg.  

What's more, most cases of leukemia are not believed to be hereditary, but certain genetic mutations and conditions can be passed along to offspring that increase the chances of developing leukemia. A condition known as Li-Fraumeni syndrome is characterized by an inherited mutation in a tumor suppressor gene known as TP53, and individuals with this condition have an increased risk of leukemia and other cancers. Other hereditary conditions that can increase the risk of developing leukemia include Down syndrome, neurofibromatosis type 1, ataxia telangiectasia, and Noonan syndrome.

I recently have a project about this area, and found out this question. hope this can make it clear to you.
