The discovery builds on previous research showing that high blood sugar appears to reduce a person's risk of a noncancerous brain tumor called meningioma. Both studies were led by Judith Schwartzbaum, associate professor of epidemiology and a researcher at the Comprehensive Cancer Center.

"Diabetes and elevated blood sugar increase the risk of cancer at several sites, including the colon, breast, and bladder but, in this case, these rare malignant brain tumors are more common among people who have normal levels of blood glucose than those with high blood sugar or diabetes. Our research raises questions that, when answered, will lead to a better understanding of the mechanisms involved in glioma development."

Glioma is one of the most-common types of cancerous tumors originating in the brain. It begins in the cells that surround nerve cells and help them function. The disease typically is diagnosed in middle age. …
