Increase in Skirt Size Adds to Breast Cancer Risk

In a study published in the British Medical Journal in September, 2014, a woman's increasing weight circumference as she ages can increase the risk of breast cancer. The study focused on self-reported waist measurements of nearly 93,000 postmenopausal women older than age 50 with no known history of breast cancer. 

The results showed that regardless of body mass index, women who go up a skirt size every 10 years between the ages of 20 and 70 have a 33 percent increase in the risk of developing breast cancer. A two-size increase every ten years was linked to a greater risk of 77 percent. Skirt size is the way the study refers to waist circumference. 

Researchers did not study the causes of the weight gain but say that because abdominal fat is more "metabolically active" than other body fat, it may cause an increase in the levels of estrogen and inflammation in the female body, which can increase the growth of breast cancer cells.

 Medical professionals already know that the larger a waist is, the more likely a person is to contract diabetes, high blood pressure and cardiovascular disease.
