It is no surprise that excess weight increases one's chances of
developing cancer. A new study suggests overweight women 55 and
older may be doubling their risk of developing acute myelogenous
leukemia (AML). Further, older women with a body mass index of 30
or more (obese) have a 140 percent higher risk of developing the
disease.
Claiming the lives of about one-third of the 33,000 leukemia cases
in the United States a year, AML is one of the deadliest kinds of
leukemia. This is due in part to its aggressive and rapidly developing
nature.
Researchers determined it was important to assess the risk factors
associated with developing AML, as the five-year survival rate is
as low as 3 percent.
Thus far, the risk factors include:
- Old age
- Excessive weight
- Hormones or genetics
Although excess weight is considered a risk factor, it has not
been discovered whether or not losing or normalizing weight can
reduce the risk of AML; however, it remains a possibility.
