Diabetes is already linked to a number of complications, but emerging evidence suggests an increased risk of cancer can be added to that list.
"We used a prospective cohort to evaluate the relationship between diabetes and cancer risk," said the study's lead author, Gabriel Lai, a cancer prevention fellow at the US National Cancer Institute. "Diabetes was associated with an 8% increase in cancer risk in women, and there was a similar pattern in men, except for prostate cancer," said Lai.
For reasons that remain unclear, diabetes was actually associated with a lower incidence of prostate cancer in men, the study found. When rates of prostate cancer were included in the mix, diabetic men's odds for cancer generally were reduced by 4%.
