Diabetes Significantly Increases Breast Cancer Risk


A new clinical study finds that adult-onset diabetes increases breast cancer risk by almost 30 percent.



As I discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, both obesity and diabetes are underappreciated risk factors for a variety of cancers, including some of the most deadly forms of cancer.  I also note in my book that breast cancer is associated with a greater number of preventable risk factors than any other type of cancer.  Now, a newly published research study, which appears in the current issue of the British Journal of Cancer, suggests that diabetes may significantly increase the risk of developing breast cancer.

This new study is based upon an exhaustive analysis of the findings of 40 separate research studies that evaluated potential links between diabetes and breast cancer.  In reviewing the cases of 56,000 women with breast cancer, the authors of this new study found that adult-onset diabetes (also known as type II diabetes) increased breast cancer risk significantly, by almost 30 percent.

While this particular study was not designed to identify an actual “cause and effect” relationship between diabetes and breast cancer risk, the finding that type II diabetes increased the risk of breast cancer only in postmenopausal women offers an important clue, as the exact same association has previously been noted between obesity and breast cancer risk (i.e., obesity appears to increase breast cancer risk primarily in postmenopausal women).  Since type II diabetes is strongly associated with obesity, it is not surprising, in my view, that this new study has uncovered a link between type II diabetes and breast cancer risk in postmenopausal women.  However, it is possible that there are more factors at work here than obesity alone, as some of the biochemical abnormalities that accompany diabetes are, themselves, suspected to be risk factors for cancer as well.

The findings of this important study add further weight to previous studies that have linked both diabetes and obesity to an increased risk of developing cancer (in addition to cardiovascular disease and other serious chronic illnesses, I might add).  Overall, the data linking obesity, and obesity-related diseases like diabetes, to an increased risk of chronic serious illnesses, including cancer, and premature death is overwhelming and beyond debate.

A Cancer Prevention Guide for the Human Race is now available in both printed and digital formats from all major bookstores.  Get your copy now, and begin living an evidence-based cancer prevention lifestyle now!


At this time, more than 8 percent of Americans are unemployed.  According to the Bureau of Labor Statistics, however, the unemployment rate for veterans who served on active duty between September 2001 and December 2011 is now more than 12 percent.  A new website, Veterans in Healthcare, seeks to connect veterans with potential employers.  If you are a veteran who works in the healthcare field, or if you are an employer who is looking for physicians, advanced practice professionals, nurses, corpsmen/medics, or other healthcare professionals, then please take a look at Veterans in Healthcare. As a retired veteran of the U.S. Army, I would also like to personally urge you to hire a veteran whenever possible.
