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.
Today is World Diabetes Day and it comes at a time when the US rate of diabetes and those at risk for the disease are higher then ever before. Most are cases of type 2 diabetes, which brings numerous challenges in itself. Many are not aware that this disease also brings an increased risk of several cancers. For those at risk, you can lower it.
A paper back in 2010 found that people with type 2 diabetes are are at twice the increased risk of developing liver, pancreas and endometrium cancers, when compared to those without diabetes. Increased risk is smaller but still evident for cancers of the colon/rectum, post-menopausal breast and bladder.
A June report released by the government show how many men and women face these risks:
– about 1 in 10 US adults have diabetes
– about 1 in 3 are at risk for developing it
– over 1 in 4 adults with diabetes are undiagnosed
The connection between cancers and type 2 diabetes appears to be – in part – due to risk factors shared by both diseases, such as obesity, poor diet and being inactive. The positive is that people can do something about these.
Eating healthy, being active, and getting to then staying a healthy weight can help people with pre-diabetes reduce the risk of many cancers and type 2 diabetes. For those with diabetes, a healthy lifestyle can reduce the risk of cancers and improve management of the disease.
If you’ve been trying to boost your heart health by eating a Mediterranean diet filled with olive oil, vegetables and nuts, and foregoing red and processed meat, a new report says you also may be lowering your risk for cancer and type 2 diabetes, all without losing weight.
A report of studies from PREDIMED, a large nutrition intervention trial, was published in the May issue of Advances in Nutrition. One study found that after almost 5 years, Mediterranean diet participants had 30% less cardiovascular disease than the control group. Another study found the Mediterranean diet groups had less type 2 diabetes, showed improvements in conditions of metabolic syndrome and had lower levels of markers for inflammation, all risk factors for cancer.
The Mediterranean diet, promoted as heart healthy, is rich in plant foods (such as vegetables, legumes, fruits and nuts), olive oil, moderate amounts of fish, yogurt, cheese, poultry and red wine, but little red and processed meats and sweets. In the PREDIMED study, researchers randomly assigned about 7500 participants to one of three groups: a Mediterranean diet (MeDiet) supplemented with olive oil, a MeDiet supplemented with nuts or they were instructed to follow a low fat diet. The PREDIMED study is a randomized, nutritional intervention trial conducted in Spain from 2003 to 2011. Read more… “Mediterranean Diet: Heart Healthy and Preventing Cancer”
