prostate cancer and obesity

When have you been diagnosed with prostate cancer?
Do you know the stage of the cancer?
Did you undergo certain treatment already?

There are some study results that indicate positive correlation among obesity and prostate cancer.
Patient that are obese a year before diagnosis of prostate cancer, are 2.6 times more likely than men with a normal weight to die of prostate cancer.
Also, obesity in the year before diagnosis is tripling the odds that the cancer would spread (metastasize).
