The article by Dr. Vineet Talwar, Director, Medical Oncology, RGCIRC explains that excessive sugar intake sets off a chain of metabolic and hormonal changes that significantly increases the risk of both diabetes and cancer. High blood sugar leads to insulin resistance and hyperinsulinemia (excess insulin), which acts as a growth signal for cells, encouraging rapid division and hindering the body’s ability to eliminate abnormal cells—a process that can support tumor development. Furthermore, sugar consumption triggers chronic inflammation and oxidative stress, weakening the immune system. The piece emphasizes that people with Type 2 diabetes face an increased risk of several cancers (liver, pancreas, breast, colon, endometrium). The key to mitigation is lifestyle change, including reducing refined sugar intake, maintaining a healthy weight, and staying physically active to improve insulin sensitivity and overall immune function.
