Currently, there is no consensus in clinical practice regarding the causes of pancreatic cancer, but some studies have found that certain factors contribute to its high incidence. For example, patients with diabetes have a higher incidence of pancreatic cancer compared to those without diabetes, and having chronic pancreatitis and other diseases also leads to a higher occurrence of pancreatic cancer. Additionally, factors such as genetic mutations are also associated with the development of pancreatic cancer. Some research has found that there is a certain correlation between genetic factors and the occurrence of pancreatic cancer. Once pancreatic cancer develops, it leads to a variety of symptoms in clinical settings.
