What causes pancreatic cancer

The causes of pancreatic cancer mainly include genetics, environmental factors, physiological factors and other pathological factors. In terms of genetics, if there is a case of pancreatic cancer in the family, the risk of the disease will increase, and certain gene mutations such as BRCA2 and CDKN2A are also associated with an increased risk of pancreatic cancer. Among environmental factors, smoking is an important carcinogenic factor. In addition, obesity, sedentary lifestyle, and unhealthy eating habits can also increase the risk of disease. Physiological factors such as chronic pancreatitis and diabetes may cause long-term damage to pancreatic cells and increase the chance of cancer. The pathological formation of pancreatic cancer often originates from abnormal proliferation of normal pancreatic tissue, which gradually develops into malignant lesions.

The genetic factors of pancreatic cancer involve several specific gene mutations. Among them, genetic analysis of pancreatic cancer families found that the significance of BRCA2, PALB2 and ATM gene mutations is relatively high. These genes play an important role in the process of cell DNA repair. Their mutations may lead to abnormal cell division, thereby increasing the risk of cancer. Among environmental factors, smoking is the most significant external inducement. Long-term intake of carcinogenic compounds produced by smoking will directly affect the health of pancreatic cells. At the same time, exposure to chemicals such as pesticides and petroleum products may also increase the probability of disease. Diabetic patients are prone to pancreatic cell dysfunction due to long-term abnormal insulin metabolism, which is one of the potential factors for carcinogenesis. Chronic pancreatitis patients have repeated damage and healing of pancreatic tissue due to the continuous inflammatory process, and the probability of incorrect repair in the cell cycle is increased, which also poses a potential risk.

In order to reduce the risk of pancreatic cancer, it is recommended to implement a healthy lifestyle: quit smoking, maintain a healthy weight, and eat a balanced diet, such as consuming more fruits, vegetables, and whole grains. Increase physical activity moderately, avoid sitting for long periods of time, and monitor the body's metabolic changes through regular physical examinations. Especially for individuals with a family genetic background, they should pay more attention to health management in daily life. At the same time, for people who have been diagnosed with diabetes and chronic pancreatitis, it is imperative to effectively control the disease under the guidance of a doctor to reduce the risk of cancer. These measures help reduce the possibility of pancreatic cancer and provide a certain degree of protection for one's own health.
