Diabetes is associated with a number of complications, but a study out of the U.S. Cancer Institute informs us that it may increase risk, mild to moderately, for a few cancers.
A new study found that women with diabetes had an 8 percent increased risk of developing cancer generally, while men with diabetes had a 9 percent higher risk when rates of prostate cancer were excluded from the calculation. The risk of dying from a cancer was also higher in people with diabetes -- 11 percent greater for women and 17 percent higher in men.
Prostate cancer is excluded because it has already been shown to decrease risk for diabetes (although we doubt anyone would trade diabetes for prostate cancer).
Risk was greatest for liver, rectal and colon cancer when the population was taken as a whole. Diabetic males showed greater risk for pancreatic and bladder cancers, whereas diabetic females showed greater risk of stomach and uterine cancer.
Mechanisms explaining these relationships are currrently unknown and much study is needed.
