Doctors explained that in addition to genetic mutations, pancreatic cancer is also related to the metabolic environment caused by obesity, diabetes, dyslipidemia and chronic inflammation. If blood sugar suddenly increases and weight loss occurs, you should get medical evaluation as soon as possible.
The early symptoms of pancreatic cancer are not obvious, and many people are diagnosed at an advanced stage. Experts say that the incidence of pancreatic cancer is not solely related to genetic mutations. Obesity, diabetes, dyslipidemia and long-term chronic inflammation can also affect the body’s metabolic environment by altering the metabolic environment.cancer cells Grow.
A research review published in the international journal Pancreatology in October 2026 summarizes the relationship between obesity, diabetes, dyslipidemia and pancreatic cancer. Research suggests that whether cancer cells can continue to grow is influenced not only by their own genetic mutations, but also by the surrounding metabolic environment, includingblood sugar Fat, insulin and chronic inflammatory response, etc., may all be involved in the development of cancer.
Zhang Jiaming, president of the Society for Precision Preventive Medicine, said that adipose tissue does not simply store calories. Particularly when there is excess fat in the intestine, fat cells can swell and become hypoxic, triggering the accumulation of immune cells and releasing inflammatory signals such as interleukin-6 (IL-6), tumor necrosis factor α (TNF-α) and leptin, which in turn affects cell growth-related pathways and creates an environment favorable for the survival of some cancer cells. Therefore, in addition to body weight, waist circumference and fat distribution are also important indicators of metabolic health.
Zhang Jiaming said that diabetes and pancreatic cancer may have a two-way relationship. Long-term insulin resistance will cause the body to secrete more insulin to control blood sugar, which can affect cell growth signals. On the other hand, some pancreatic cancers may also interfere with blood sugar regulation before diagnosis. The study found that about a third of patients with pancreatic ductal adenocarcinoma developed new diabetes 6 months to 3 years before diagnosis.
Zhang Jiaming reminded that most new-onset diabetes is still related to general metabolic problems. However, if blood sugar control is basically stable but increases significantly in a short period of time, accompanied by uncontrolled food intake and persistent weight loss, medical evaluation should be sought. This cannot be attributed solely to aging or change in lifestyle habits.
Zhang Jiaming suggested that the public should regularly monitor changes in blood sugar, blood lipids, waist circumference and weight. Don’t just see if a single health checkup costs more than the norm. They should also compare data across years and note trends such as year-over-year increases in blood sugar, increases in waist circumference and decreases in muscle mass. Improve metabolic health and risk of chronic inflammation through a balanced diet, regular exercise, maintaining a proper weight, and adequate sleep. However, metabolic abnormalities do not necessarily mean pancreatic cancer. If sudden changes in blood sugar and unexplained weight loss occur, further decision should be taken by the physician.
Summary FAQ
-
Studies have shown that the growth of cancer cells depends not only on genetic mutations, but is also influenced by the metabolic environment such as blood sugar, fat, insulin, and chronic inflammation. These factors may provide more favorable survival conditions for cancer cells.
-
When there is too much visceral fat, fat cells can cause immune responses due to inflammation and hypoxia, and continuously release inflammatory signals such as IL-6 and TNF-α, thereby promoting the growth of some cancer cells. Therefore, waist circumference is also an important indicator.
-
If your blood sugar is basically under stable control, but it increases significantly in a short period of time, and your food intake does not decrease, but your weight continues to decrease, you should not consider it simply as aging or changes in lifestyle habits, and you should consult a doctor for evaluation as soon as possible.
