About one of every two American adults has or is at risk of having diabetes, with approximately a third of those with diabetes unaware they have it, finds a new study that offers important insights into cancer risk. People with type 2 diabetes are at increased risk for many of the most common cancers, including liver, colon and postmenopausal breast.
The study was published in The Journal of the American Medical Association.
Study authors used various national health survey data conducted periodically from 1988 to 2012. Participants had answered health questions and gone in for an exam, where they gave blood samples and had their weight and height measured. Anyone who reported a previous diagnosis of diabetes went into the diabetes category. Those with various measures of blood sugar levels over a set amount were categorized as having either undiagnosed or pre-diabetes.
Using one set of measures with the most current available data (2011-12), 14 percent of adults have diabetes. Yet about a third of those with signs of the disease have not been diagnosed. Another set of blood sugar measures puts the figure at 12 percent of adults having diabetes with a quarter of these people having the disease undiagnosed.
And another third of adults – slightly more – have prediabetes, a condition that shares many risk factors with common cancers.

Eat healthy, be physically active. We talk about these recommendations a lot for cancer prevention. Now a major new review of the evidence concludes that if you are one of the 86 million Americans at risk of developing type 2 diabetes, you can reduce your risk of this disease by participating in a program that combines both diet and physical activity. That means you’ll also have lower risk for many cancers.
Reports in the past few years have found that having type 2 diabetes increases the risk of several cancers, such as liver, pancreas, endometrium, colon/rectum, breast, and bladder. We talk about why that might be here with our expert.
Today’s recommendations were published in the Annals of Internal Medicine and they come from the Community Preventive Services Task Force, an independent group of experts. The task force found 53 studies that had programs encouraging people at risk of type 2 diabetes to improve their diet and increase their physical activity. All the programs used trained providers and lasted at least three months, with an average of about a year.
In total, there were 66 programs. Continue reading
Nuts are in fashion, nutritionally speaking, especially for heart health. Now, a new study finds that if you eat a handful of nuts several times a week that may help lower your risk of cancer.
Study results on nut consumption and cancer prevention have been inconsistent. In this systematic review and meta-analysis published in Nutrition Reviews, the researchers evaluated 36 studies – both large population studies and clinical trials – examining the relationship between eating nuts and risk of cancer or type 2 diabetes.
By comparing people who ate the most nuts (typically at least 4-5 times per week) to those who ate the least (typically 1 time per week or less), the researchers found that the high nut eaters had 15 percent lower risk of cancer overall. In specific cancers, they found lower risk for colorectal, endometrial and pancreatic cancer. They did not find any significant difference for risk of type 2 diabetes. Continue reading
