Links between diabetes, obesity, and cancer risk

Scientific research continues to establish strong connections between type 2 diabetes, obesity, and increased risks for cancer and organ failure. New data published in the British Medical Journal clarifies the impact of dietary habits, specifically regarding potato preparation. Frequent consumption of French fries is linked to a higher risk of type 2 diabetes: those eating them three times a week face a 20 percent increased risk, rising to 27 percent for those eating them five times a week. Conversely, boiling, baking, or mashing potatoes shows a much lower correlation, with only a 5 percent increased risk for those consuming them three times a week. Kawther Hashem of Queen Mary University of London noted that potatoes can remain part of a healthy diet depending on cooking methods.

Regarding cancer risks, a Danish study monitoring adults from 1996 to 2022 found that individuals with type 2 diabetes face a cancer risk twice as high as the general population, with an incidence rate of 16.6 per 1,000 people compared to 7.7 per 1,000 in those without the condition. Between 2010 and 2022, new cancer rates were 22% higher in women and 12% higher in men with type 2 diabetes. The disparity is most significant in obesity-linked cancers, which were 45% more common in men and 30% more common in women with the disease. Specific increases include an 8% higher rate of breast cancer in women and colorectal cancer increases of 17% in men and 14% in women. Notably, the risk of pancreatic cancer is 2.5 times higher for those with type 2 diabetes. Tine Laurberg, a senior researcher at Aarhus University Hospital, emphasized that cancer must now be recognized as a major long-term complication of type 2 diabetes requiring increased attention in preventative care and early diagnosis.
