A Swedish study has found that elevated blood sugar in women is linked with increased risk of developing cancer.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.
While previous studies have shown that cancer risk for some cancers is higher for people with type 2 diabetes, this study suggests that something could be happening to trigger cancer much earlier, as glucose levels begin to rise. The scientists also found that the blood sugar levels gradually rose over the period of the study, which they suggest means that cancer risks would also continue to rise unless glucose levels were brought down by some means. The results were no different when they took Body Mass Index (BMI) into account.
The study provides further evidence for an association between abnormal glucose metabolism and cancer. If you ask me - I think this has to do with the pH levels of the blood. It is well known that cancer manifests in blood levels of higher acidity. Poor diabetic control can result in higher acid levels in the blood. The catch 22 is poor diabetic control leaves your entire blood chemistry off kilter and it cannot defend any rogue cells - especially those associated with malignant growth (i.e. cancer!)
