Breast cancer cells are LOADED with insulin receptors. That's important to know for preventing/treating it. Why? Read on... In 159 breast tumors, insulin receptor content was more than 6 times higher than in normal breast tissue. And the receptors worked: they bound insulin and switched on. Many cancer cells favor a form of the insulin receptor (IR-A) that acts mainly as a growth signal, not a sugar-handling one. Insulin tells these cells to grow. So what happens when insulin runs high? 512 women with early breast cancer had fasting insulin checked. Highest vs lowest quarter: 2x the distant recurrence, 3.1x the death rate. In the Women's Health Initiative, researchers measured insulin in about 1,650 postmenopausal women drawn from a cohort of 93,676. In women not on hormone therapy, the top quarter of insulin had 2.4x the breast cancer risk. And the obesity link mostly faded once insulin was accounted for. Few doctors check fasting insulin. Fewer still know that Low-carb/Keto/Carnivore is the most direct way to bring it down. I've made videos on this (see below). If high insulin goes with more breast cancer AND worse outcomes, why isn't fasting insulin part of every breast cancer workup? Studies and my videos below... – at Tennessee, USA
