A new study suggests that excessive body weight may be a risk factor for
prostate cancer.
The study in the September online issue of Cancer Epidemiology, Biomarkers and
Prevention showed that men who were overweight or obese in the young adulthood
were at high risk of advanced prostate cancer.
The result is suggestive however because the study is not a trial meaning that
it does not prove obesity is a cause for the increased risk of prostate cancer.
Obesity has been linked to other types of cancer such as colorectal cancer and
breast cancer, both promoted by some hormones.
In the case of colorectal cancer, obesity hormone leptin is over expressed;
prompting researchers to speculate that this hormone may have something to do
with the cancer.
In the case of prostate cancer, OTC hormone has been known to promote the growth
of the cancer.
Although the current study does not prove obesity as a risk factor raises the
risk of prostate cancer, some health observers suggest that certain hormone may
affect both obesity and prostate cancer meaning that both obesity and prostate
cancer result from the same or similar cause.
For the study, Brenda Hernandez at the Cancer Research Center of Hawaii looked
at health data from 84,000 men and found men who were obese or overweight at 21
were actually at a lower risk localized or low grade prostate cancer.
But excessive weight gain in men’s young adults was linked with elevated risk
of advanced and high grade prostate cancers for white men. For black men,
excessive weight gain raised risks for localized and low grade prostate cancer.
One health observer at foodconsumer.org suggests that poor diet may be a common
cause for increased risk of not only prostate cancer but also other cancers such
as colorectal cancer and breast cancer.
And evidence is abundant to suggest that diet may be the major determinant for
prostate cancer risk.  Foodconsumer.org has reported on many studies that
indicate that a modified diet may help reduce the risk of prostate cancer.
