Extra fat on our bodies leads to higher levels of circulating insulin and estrogen, both of which can significantly increase the risk of cancer.
Fat cells known as adipocytes, use insulin to remove sugar from the blood and store it as fat inside of themselves. When we are overly fat, the receptors on the fat cells can become insensitive to the effects of insulin (they don’t respond well to it and thus require much more of it to work to keep blood sugar at safe levels). This is known as hyperinsulinemia. In addition, fat cells also produce estrogen, so when we are overly-fat, we are producing too much insulin and estrogen both of which can lead to heart disease, blindness and cancer.
This recent study shows the impact on cancer rates in the UK due to the worldwide epidemic of over-weight and obese people.
