Intensive Lifestyle Intervention May Lower Cancer Risk
Overweight and obesity
have been shown to be associated with certain types
of cancers. These cancers include breast cancer,
colon cancer and other cancers. One may wonder if
living a healthier lifestyle can lower the risk of
obesity related or overweight related cancers. So
some investigators, using results from the Look
AHEAD (Action for Health in Diabetes) study,
attempted to determine if intentional weight loss
could reduce the risk of cancer. And the
researchers concluded that it could.
The Look AHEAD study
consisted of 16 U.S. study centers. The study was a
randomized controlled trial that used an intensive
lifestyle intervention (ILI) method similar to that
used in the Diabetes Prevention Program (DPP) study.
The Look AHEAD study was done to determine if
intentional weight loss could reduce “cardiovascular
morbidity and mortality in overweight individuals
with type 2 diabetes.” The study consisted of 5,145
participants and it was scheduled to conclude in
2012.
While the prevention of cardiovascular morbidity and
mortality in overweight individuals with type 2
diabetes was the primary focus of the study, cancer
was one of the outcomes that the investigators
wanted to look at. Therefore, cancer incidence was
given attention. “Cancer
incidence was defined as the first reported
occurrence of a malignant tumor other than
nonmelanoma skin cancer.” The investigators looked
at medical records, death certificates, hospital
records and emergency department records to
determine cancer incidence in Look AHEAD
participants.
The investigators concluded the following: “An
ILI aimed at weight loss lowered incidence of
obesity‐related cancers by 16% in adults with
overweight or obesity and type 2 diabetes. Although
the result was not statistically significant, this
finding provided evidence that patients with obesity
can reduce their cancer risk through weight loss.”
Stressing the importance of weight loss for people
with obesity can lower the risk for cancer. And
making weight loss recommendation to obese patients
is something that healthcare providers should do.
