The first study to show that obesity can accelerate the directly

progression of acute lymphoblastic leukemia (ALL) is carried out on

The Saban Research Institute for Childrens Hospital Los Angeles and was

associated with an increased incidence of many types of cancer, including

"Given the high prevalence of obesity in our society, we felt it was

critical to determine if the increase in overweight causes

of leukaemia and no other associated exposure, "says Steven d.

Mittelman, MD, PhD, a paediatric endocrinologist who led the study.

Dr. Mittelman and his colleagues a high-fat diet used for the generation of obesity

in two mouse models for all. Mice were randomised to a high-fat or a

control diet. the researchers found that obesity increases the risk of

ALL in both models, especially in older mice. This comment was

According to the type of a cumulative effect with other

exposure related cancers, such as lung cancer with regard to smoking and

As a result of breast cancer increased estrogen exposure. compliance with the

difference in older animals also agreed with the other obesity

effects of cumulative exposure such as heart disease, diabetes, and

arthritis.

"Our results are consistent with the epidemiological data which show that a

higher incidence of leukemia in obese adults and proposes that this

comments are actually due to obesity, and some do not connected

genetic, socio-economic, or lifestyle factor, "Dr Mittelman, closed

who is also an Assistant Professor of Paediatrics and Physiology &

Biophysics at the Keck School of Medicine of the University of Southern

California. "This information mean that certain hormones or factor in obesity

individuals, maybe produced by fat tissue itself, the signal of leukemia

cells to grow and divide. leukemia is the most common type of

cancer, obesity can understand how increasing the frequency

could have significant public health consequences. "
