When diabetes develops, the pancreas’s ability to secrete insulin and regulate blood sugar is already significantly impaired. Because insulin can no longer function properly, patients must rely on medication or injections. Beyond glucose regulation, the pancreas is essential for digesting and absorbing fats, proteins, and carbohydrates. If the organ is damaged, these vital functions can grind to a halt. Experts suggest that the primary cause of this damage is closely linked to diet; as meat consumption rises, pancreatic diseases are increasing due to the excessive intake of animal and saturated fats.
Approaching 10,000 cases annually: Is a changing diet to blame?
Among all pancreatic conditions, cancer remains the most serious. According to January 2026 data from the Korea Central Cancer Registry, there were 9,748 newly diagnosed cases of pancreatic cancer in 2023—an increase of approximately 1,000 cases compared to 2021. This upward trend is expected to continue. The incidence is nearly identical between genders, with 4,925 men and 4,823 women diagnosed. Key risk factors include smoking, diabetes, chronic pancreatitis, and genetics. However, much like the recent surge in colorectal cancer, Western-style eating patterns—characterized by high animal fat intake—are having a profound impact.
Dietary patterns and the shift from traditional meals
Pancreatic cancer risk is heavily influenced by the excessive consumption of meat, fat, and carbohydrates, as well as the resulting obesity. Data from the Korea Disease Control and Prevention Agency indicates that high intake of processed meats (such as sausages, ham, and bacon), red meat, refined white flour, fried foods, and sugars may elevate risk. Conversely, a diet rich in fiber—including vegetables, fruits, legumes, whole grains, fish, and poultry—helps reduce body fat and may lower the risk of cancer. This marks a significant shift from the past, when diets were primarily centered on seasoned vegetables.
The critical link between blood sugar control and cancer risk
The pancreas is the sole site of insulin production. When frequent blood sugar "spikes" occur, the organ is placed under immense strain. Over time, this exhausts the insulin-secreting function, leading to chronic diabetes. The link between these two conditions is becoming increasingly clear: according to the National Cancer Information Center, the prevalence of diabetes among pancreatic cancer patients is roughly 30%, more than triple the 9% rate found in the general population. For those with long-term diabetes or frequent glucose fluctuations, proactive pancreatic cancer screening is highly recommended.
Recognizing the symptoms: Jaundice, pain, and weight loss
Pancreatic cancer is notoriously difficult to detect, as it typically presents no symptoms in its early stages. By the time physical pain appears, the disease is often advanced. The most common symptom is pain in the epigastric region—the center of the upper abdomen—though pain can also radiate to the back. Other warning signs include jaundice (yellowing of the eyes), dark brown or reddish urine, indigestion, and stools that float. Unintentional weight loss exceeding 10% of one's usual body weight is also a major red flag. Monitoring these risk factors and maintaining awareness of pancreatic health is essential for early intervention.
