Having diabetes increases the risk of cancer, especially for women, according to a new study. We are talking here of both type 1 and type 2 diabetes.
A new study has shown that diabetes significantly increases the risk of developing cancer. For women, the risk is even higher. Specifically, researchers at the George Institute for Global Health found that diabetes (type 1 and type 2) increased the risk of leukemia and cancers of the stomach, mouth and kidneys in both women and men. In contrast, women with diabetes are less likely than men to develop liver cancer. These results were published in Diabetologia.
According to the lead author of the study, Dr. Toshiaki Ohkuma, a researcher at the George Institute for Global Health, “the link between diabetes and the risk of developing cancer is now firmly established… The number of people diabetes has doubled globally over the past 30 years, but we still have a lot to learn about this disease. It is vital that we do more research so that people with diabetes and the medical community are aware of the increased risk of cancer in this population”.
In the cohort, women with diabetes were 27% more likely to develop cancer than non-diabetic women. In men, the risk was 19% higher. Overall, women with diabetes were 6% more likely to develop some form of cancer than men with diabetes. The risk of developing kidney cancer (11% higher), oral cancer (13% higher), stomach cancer (14% higher) and leukemia (15% higher) were significantly higher in women with diabetes than men with this disease. In the case of liver cancer, the risk was 12% lower in women with diabetes than in men with diabetes.
“Historically, we know that women are often under-treated when they experience the first symptoms of diabetes, are less likely to receive intensive care, and do not take as many medications as men. This might explain why women with diabetes have a greater risk of developing cancer, but without more research, we can not be sure of that, “says Dr. Sanne Peters, another author of the Institute’s study.
According to the American Diabetes Association, as of 2015, 30.3 million Americans, or 9.4% of the population, suffer from diabetes.. It has even progressed faster than expected, reflecting a real growth of the epidemic. The leading causes of diabetes are overweight, obesity, poor diet, sedentary lifestyle and low physical activity. Insulin resistance (type 2 diabetes) affects more than 90% of people with diabetes. Insulin-dependent diabetes mellitus (IDDM), known as “type 1 diabetes”, affects about 10% of people with diabetes.
