What Causes Leukemia?

No one knows the exact cause of leukemia, but we do know what some of the risk factors are. Through identification of these factors, we can determine who is more likely to suffer from this deadly cancer. This allows for earlier detection and treatment and may result in a high number of remissions.

Radiation is one of the primary risk factors that has been connected to leukemia. Exposure to high levels of radiation has been proven to be a major factor in the onset of leukemia. This was proved after the disaster at Chernobyl, when many people developed this form of cancer due to the high radiation levels.

Certain chemicals have also been associated with the development of leukemia. While not defined as actual causes, it has been noted that people working with formaldehyde and benzene (as in laboratories) are at higher risk for developing leukemia. Without proper precautions, the level of risk rises dramatically.

Specific problems with chromosomes may predisposition certain people to leukemia as well. Chromosomal problems such as Down's Syndrome and other similar problems are linked to the onset of leukemia and is something to be considered in those with a known chromosomal disorder. Regular testing can ensure early detection and treatment may be begun sufficiently early to yield good results.

While some believe that exposure to electromagnetic fields, such as those found near power stations or under power lines, caused cancer, this has yet to be proven. In fact, no study has even proven a very strong link between exposure to electromagnetic fields and leukemia, so this is not considered to be a great risk factor.

Someone who has already suffered from one type of cancer may be at higher risk to develop leukemia. This is thought to be caused in part by the treatments for the original cancer, namely chemotherapy. The leukemia doesn't usually appear for several years however and my not be associated with the cancer-fighting drugs taken up to a decade before. It is something to watch for though, if you have a history of cancer.

One last risk factor for leukemia is disease. There are certain diseases that can make you more susceptible to leukemia. The two most prominent diseases that have been associated with the development of this cancer are myelodyplastic syndrome (a blood disease) and the human T-cell leukemia virus. Both of these diseases tend to boost your likelihood of contracting leukemia.

Again, while we can suspect and guess at the causes of this devastating disease, leukemia does have certain risk factors. If you think you might be at risk, it is always best to speak with a doctor, just to make sure.
