- Insulin May Fuel Breast Cancer Growth
Insulin is a hormone most people think of in terms of blood sugar and diabetes. Did you know it also has growth promoting properties? That’s good if you’re a teenager and going through a growth spurt but not at all good if you’ve been diagnosed with cancer.
Research has shown that a high blood insulin level correlates with poorer prognosis for women with metastatic breast cancer. This is important to know because insulin can be lowered, and this improves chances of survival.
This finding comes from research presented at the Advanced Breast Cancer Third International Consensus Conference on Nov. 6, 2015. It has been known for a long time that women with type 2 diabetes are more likely to develop breast cancer. Both high blood sugar and high blood insulin are known to promote the growth and spread of tumors. Now studies have shown that you don’t have to be a diabetic to be at higher risk – women with normal blood sugar but high insulin are also in danger.
People with elevated blood insulin are known to have insulin resistance or metabolic syndrome. You can ask your doctor for a blood test to check your insulin level. This is a fasting test. An ideal level is 3 or 4. Clues that you might have elevated insulin include being a type 2 diabetic, having polycystic ovarian syndrome, a fatty liver, or carrying excess fat around your waist.
