MYOS Muscle Matters: Muscle Health and Breast Cancer Survival

If you are a woman over the age of 40, perhaps you may wonder why muscle health should matter to you. A quarter of a century ago, you may have been the star midfielder on your high school soccer team. However, you retired your soccer jersey many years ago when your first child was born and enjoy driving your fully-loaded, Honda Odyssey minivan as a proud Soccer Mom these days instead. In reality, muscle health likely matters more now than it did when you dominated the soccer field once upon a time.

One of the reasons why muscle health needs to become a priority as we get older has to do with a landmark study involving 8,762 men that was published in 2008 by Researchers at the Karolinska Instiutet, Huddinge, Sweden, University of South Carolina and University of North Texas [1]. These researchers reported that “muscular strength is inversely and independently associated with death from all causes and cancer in men, even after adjusting for cardiorespiratory fitness and other potential confounders.” To put it in plain English: there is a clear relationship between muscle health and death from all causes in men that participated in this clinical trial. You may be wondering why this study is relevant to discuss as it was focused on men and you are a woman – well, there is more to come.

In 2018, a major study was published by Researchers at Dana Farber Cancer Institute, an affiliate of Harvard Medical School that examined the impact of muscle and adiposity (fat tissue) on survival in 3,241 women with non-metastatic breast cancer [2]. The Researchers were particularly interested in the impact of sarcopenia (low muscle mass) on non-metastatic breast cancer survival. Women with low muscle mass at the time of breast cancer had higher mortality when compared to women with good muscle health in comparison. For women with low muscle mass at the time of breast cancer diagnosis, the hazard ratio was 1.41 with a 95% confidence interval between 1.18 and 1.69. This means that for a woman with low muscle mass that participated in this clinical trial, her risk of mortality was 41% higher than that of a woman with good muscle health!

However, this blog entry was not written to bring you a message of doom and gloom but rather one of hope. Going for regular breast cancer screening enables breast cancer to be caught early and the Medical Oncologists of 2020 are armed with a much more powerful arsenal to combat breast cancer with relative to their peers from 2000. Although some things in life may be beyond your control, many things such as improving your muscle health are very much within your control. By going to the gym and lifting weights a couple of times a week, ensuring that your diet provides you with enough protein and adding a nutrition product called MYOS Physician Muscle Health Formula to your diet, you can transform your muscle health.
