Link: High Blood Sugar Linked with Cancer
"Although past research has shown that having diabetes or an elevated glucose level may increase cancer risk, the evidence has been mixed and many of the studies to date were relatively small," says study coauthor Jonathan Samet of Johns Hopkins.
This study was anything but small, involving 1,298,385 Korean men and women aged 30 to 95 who were members of the National Health Insurance Corp. Participants provided information on their lifestyle and medical histories, and fasting blood samples were taken at biennial medical examinations.
Those with the highest fasting glucose levels (greater than 140 mg/dL) had a higher death rate from all cancers combined. For men, pancreatic cancer had the strongest link while there were also significant associations with cancers of the esophagus, liver and colon/rectum. For women, the strongest links where to cancers of the liver and cervix.
