High blood sugar levels and diabetes are risk factors for developing some types of cancer, according to a new study. Researchers studied more than 1 million Korean patients for 10 years and tracked new cancer cases and deaths caused by cancer. Study results showed patients with diabetes and those without diabetes but with higher fasting blood sugar levels were more likely to develop cancer or die from cancer. The group with the highest fasting blood sugar levels had higher death rates from all cancers combined.
Men with high blood sugar or diabetes were more likely to develop cancers of the pancreas, esophagus, liver and colon and women with these predispositions were more likely to develop liver and cervical cancer. Researchers say glucose intolerance may be one way obesity increases cancer risk, and rising obesity rates may increase future cancer rates.In conclusion researchers say their study provides more information on glucose intolerance, an emerging cause of cancer and the adverse consequence of obesity .
