According to a new study published by Harvard University and University of Toronto scientists, women with large breasts may be prone to diabetes. However, critics have said that there are many factors that lead to the onset of diabetes and the size of a woman’s breasts is not the only factor involved.

The researchers looked at 92,106 women with an average age of 38. The researchers then asked each woman what their bra size had been when they were 20. The researchers then looked at instances of women who had developed type 2 diabetes.

The research found that women who had had a D cup or larger at 20 were around three times more likely to develop type 2 diabetes, while women who had a B or a C cup aged 20 had a slightly higher risk of developing diabetes than women who wore an A cup aged 20.

One of the risk factors for developing diabetes is being overweight or having a waist size of over 31.5 inches for women, or over 37 inches for men. More women with larger cup sizes tend to be overweight that those with smaller cup sizes, therefore it is perhaps little wonder that larger breast sizes may equate to a higher risk of type 2 diabetes.
