What causes pancreatic cancer

summary

Pancreatic cancer is a disease with many causes. Let's talk about what causes pancreatic cancer.

What causes pancreatic cancer

First: smoking. Animal experiments have proved that feeding animals with nicotinic acid water can cause pancreatic cancer. The results of a large sample survey show that the chance of pancreatic cancer in smokers is 1.5 times higher than that in non-smokers, and the higher the amount of smoking, the higher the chance of pancreatic cancer. For example, the incidence of pancreatic cancer in smokers with one pack of cigarettes per day is 4 and 2 times higher than that in non-smokers in both sexes. The above data show that smoking can induce pancreatic cancer in some people The incidence of pancreatic cancer.

Second: improper diet. In recent years, some scholars attribute the increase of pancreatic cancer to improper diet structure. Animal experiments have proved that animals fed with high protein and high fat diet can accelerate the renewal of pancreatic duct cells and enhance their sensitivity to carcinogens. Domestic scholars Shen Kui and others clearly put forward that diet structure is closely related to the occurrence of pancreatic cancer, and they eat more meat Japanese scholars have pointed out that the incidence rate of pancreatic cancer in Japan has increased in recent years, which is related to Europeanization of Japanese dietary structure, that is, eating high protein and high fat. Some scholars believe that there are more opportunities for pancreatic cancer among coffee drinkers, but no further confirmation has been made.

Third, diabetes and pancreatic cancer. It is well known that people with diabetes are prone to pancreatic cancer, but recent studies have shown that the incidence of pancreatic cancer in patients with diabetes is twice that in patients without diabetes, and there is an increasing trend; Some people think that it is 2~4 times the normal population, and even reported that the incidence rate is 12.4% of the digestive system malignant tumors. But the real relationship between them is not clear.

matters needing attention

The etiology of pancreatic cancer is not yet clear. Incidence rate of pancreatic cancer is related to smoking, drinking, high fat and high protein diet, excessive consumption of coffee, environmental pollution and genetic factors. It has also been noted that there is a certain relationship between patients with chronic pancreatitis and the incidence of pancreatic cancer, and it has been found that the incidence of pancreatic cancer in patients with chronic pancreatitis is significantly increased; in addition, there are many factors that have a certain relationship with the occurrence of the disease, such as occupation, environment, geography and so on.
