As epidemiologic evidence suggests diabetic men have a slightly lower prostate cancer risk than non-diabetic men. Seattle researchers examined this association in a prospective cohort study of 35 239 men, 50–76 years old, in Washington State who completed a baseline questionnaire between 2000 and 2002. Incident prostate cancers as of 31 December 2004 were identified through the SEER registry.
They found that diabetic men had a slightly lower risk of prostate cancer than non-diabetic men (hazard ratio (HR) 0.83). Insulin users overall and insulin users with diabetic complications had decreased risks, compared to non-diabetic men (HR 0.49) and (HR 0.36), respectively. Oral medication use for diabetes was not associated with prostate cancer. Insulin is likely a marker of severity of diabetes.
The researchers concluded: “Future studies of this association should consider diabetes type, treatment, severity, complications and biomarkers”
An interesting association that might be somewhat reassuring for diabetic men.

For the diabetic patient, it’s not the cholesterol that’s the problem. It’s the number of LDL particles, especially small LDL particles. To see the real risk, use the NMR LipoProfile(r) test, the only test that directly measures the number of LDL particles and the number of small LDL particles – the particles shown to be more predictive of CHD events than LDL-C.
