new research linking high blood sugar to cancer risk:The Diabetes Blog relays
Researchers identified 2,478 incident cases of cancer from records of 33,293 women and 31,304 men who participated in the study. Participants were recruited in the mid-1980s at age 40, 50 and 60 and the study covered a 13-year period. The records included levels of glucose in the blood when fasting and after receiving an infusion of glucose. Researchers calculated the cancer risk relative to blood glucose while adjusting for: age, year of enrollment, fasting time and smoking status. Women with blood sugar levels higher than normal have a total higher risk for cancer while for men the risk was unchanged at higher blood sugar levels. The overall risk of developing cancer for women in the top 25% of fasting blood glucose levels was 26% higher than those in the bottom 25%. Women with high fasting glucose levels had a higher risk of pancreatic, breast and endometrial cancers, while the increase in risk for malignant melanoma was two times higher.
