Pancreatic Cancer and Insulin Resistance: The Overlooked Driver (2026)
Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest human malignancies, with a five-year survival rate stubbornly below 15% despite decades of advances in surgery, chemotherapy, and molecular oncology. Most discussions focus on late diagnosis, aggressive genetics, or therapeutic resistance. Far less attention is paid to a quieter but increasingly evident factor: insulin resistance and metabolic dysfunction . Emerging evidence suggests that pancreatic cancer is not merely influenced by metabolic disease—it may be deeply intertwined with it . Insulin resistance often precedes diagnosis, worsens prognosis, and biologically fuels tumor growth. Yet it remains largely absent from staging systems, risk stratification, and treatment frameworks. A 2023 study from researchers at University of British Columbia’s Faculty of Medicine reveals a direct link between high insulin levels, common among patients with obesity and type 2 diabetes, and pancreatic cancer. The study, published...
