Another concern for diabetics and a new way to predict a woman's chances of getting cancer.
Top cancer researchers say they've come up with a new math model to predict a woman's risk of breast, ovarian and womb cancer. The predictions are based on common risk factors such as the number of children a woman had, her body mass index, her use of oral contraceptives and her menopausal status. For example, a woman's chances of getting endometrial cancer during the next 20 years is anywhere from less than one percent to nearly 30 percent - depending on her risk factors.

Type 2 diabetics who have severe hypoglycemia are at higher risk of cardiovascular disease, according to a new study. Patients with severe hypoglycemia have dangerously low blood sugar levels. Researchers from the US, Japan and the Netherlands analyzed several studies of nearly one million patients and found severe hypoglycemia was associated with double the risk of cardiovascular disease. The study's authors say patient education and close monitoring of blood glucose levels can be useful in preventing hypoglycemia.

And a group of health experts says the current definition of chronic kidney disease is leading to over-diagnosis. In 2002, CKD was classified as the presence of kidney damage or decreased kidney function for three months or more. Under that definition, one in eight adults in the United States and about half of people over 70 have the disease. But experts say the low rates of kidney failure suggest many cases will never progress to severe disease. They say the new definition leads to wasteful spending on unnecessary care.
