Obesity’s link to certain cancers puts wellness programs on trial

Obesity is a disorder in which a individual has an unhealthy amount and/or distribution of bodyfat. To measure obesity, researchers typically utilize a scale known as the body mass index. BMI is calculated by dividing a individual's weight by their height squared. BMI offers a more accurate way of measuring obesity than weight alone, and for some people it is a fairly good index of body fatness.

Other measurements that reflect the distribution of body fat–that is, Whether more fat is taken across the buttocks or the gut –are increasingly being used alongside BMI as signs of obesity and disease risks. These dimensions comprise waist circumference and the waist-to-hip ratio. “The issue with excess visceral fat is the fact that it affects certain processes in your entire body. This includes the way the body handles hormones, such as insulin and estrogen,” says Karen Basen-Engquist,” Ph.D.. , professor in Behavioral Science at MD Anderson. “All of this often leads to a heightened cancer risk by changing how and when cells die,” she says.

The link to body weight is stronger for some cancers than for others. By way of example, extra body weight is thought to be an issue in more than half of endometrial cancers, where as it is connected to a lesser part of different cancers. The connections between body fat and cancer are complex and are not Yet fully understood. By Way of Example, while research have found that excess Weight is linked with an increased risk of breast cancer in women after Menopause, it does not appear to increase the chance of breast cancer before menopause. The reasons for this aren't apparent.
