Prostate
cancer is one of the commonest cancers among men and if diagnosed during the
early stages, can be treated very successfully. Like other cancers, obesity
increases the risks of aggressive prostate diseases. Recent studies by
researchers show that fat surrounding the prostate of overweight or obese men with
prostate cancer provides a favorable environment for the growth of the cancer.
The
fat is mostly an underrated organ. It is not just an energy store but it
secretes wide range of growth factors, cytokines and hormones, including leptin and adiponectin, and it is a major player in the immune system, which protects the body from infection and disease. But too much fat in the body can cause these systems to go haywire
and can increase risks of diabetes, cardiovascular disease and cancer.
In
a study, researchers found that regardless of the type of the prostate
disease, overweight men had various
levels of gene activity in the fat surrounding their prostates, compared to
lean men. This also includes genes that encode proteins involved in immunity,
inflammation, cell growth, proliferation, fat metabolism and programmed cell
death.
Experts say that in an increasingly obese population, it is important to
understand how fat, and specifically the fat surrounding the prostate can
influence the growth and severity of prostate cancer and may provide an
opportunity for implementing personalized lifestyle as well as therapeutic
strategies.
