Dutch researchers says, People with type 2 diabetes have a heightened risk of developing breast and colon cancer, and they’re also more likely than others to die of these diseases.
Their conclusions are based on a review of 20 previous studies involving almost 2 million people. Overall, they found a 23 percent increased risk of developing breast cancer and a 38 percent increased risk of dying from it among people with type 2 diabetes. The data also showed a 26 percent greater risk of developing colon cancer and a 30 percent higher risk of dying from that malignancy.
De Bruijn lead researcher Kirstin De Bruijn, a doctoral student in the surgery department at Erasmus University Medical Center in Rotterdam, admits the findings show only an association between diabetes and an increased risk for these two cancers.
The study findings are scheduled for formal presentation Sunday at the European Cancer Congress in Amsterdam, the Netherlands.
Type 2 diabetes, which is linked to being overweight and sedentary, is a growing concern worldwide. In the United States, 5.8 million children and adults have the disease, and the overwhelming majority have type 2. People with this disease have elevated blood sugar levels because they don’t make or use the hormone insulin properly.
For their study, De Bruijn’s team analyzed research published between 2007 and 2013. This type of study, called a meta-analysis, attempts to uncover a common thread in a number of previous studies. In total, about 1.9 million patients with breast or colon cancer, and with or without diabetes, were included.
In lieu of that, the best way to reduce the risk of cancer and diabetes is to live a healthy lifestyle and maintain a normal body weight.
The data and conclusions of research presented at meetings are typically considered preliminary until published in a peer-reviewed medical journal.
