The latest US medical research shows that if older people are obese, the risk of pancreatic cancer is the most lethal cancer. If men and women are seriously overweight, they will be more likely to develop pancreatic cancer in 5 years than 45% of adults who are overweight. In addition, the study group also stressed the need for exercise. Regular exercise can reduce obesity and avoid type 2 diabetes, thereby reducing the risk of pancreatic cancer.
In addition, researchers at the University of California, Los Angeles have also conducted experiments on mice. They let mice eat a high calorie and high-fat diet, resulting in obesity. At the same time, there are problems such as abnormal metabolism and increased insulin level. Pancreatic tissue produces inflammatory reaction and abnormal cancer lesions, and the number will also increase abnormally. These abnormalities are the precursors of pancreatic cancer.
Of course, it will take a long time for cancer lesions to really turn into malignant tumors. Therefore, before turning into real cancer tumors, changing living habits and adopting low-fat and low calorie diet may help to prevent cancer.
Smoking is the only known risk factor for pancreatic cancer.
A large number of prospective and case-control studies abroad show that the risk of death in smokers with pancreatic cancer and non-smokers is 1.6-3.1:1. Experimental studies have proved that carcinogens in tobacco leaves can cause canceration of pancreatic duct epithelium, and the age of onset will be 10 to 15 years earlier. Therefore, it is particularly important to quit smoking and avoid the harm of "second-hand smoke" and "three hand smoke".
In addition, the incidence of familial pancreatic cancer is 3-13 times that of those without family history. It is reported that 1 of the family members are suffering from pancreatic cancer, and the risk of pancreatic cancer is 4 times that of the general population. For example, the incidence of pancreatic cancer is 12 times higher than that of the general population, and the incidence of 3 cases is as high as 40 times.
It should not be taken lightly that recurrent chronic pancreatitis, pancreatic duct stones or calculous pancreatitis also have the tendency of canceration, which can be considered as a precancerous lesion. Attention should be paid to the treatment of primary diseases and close follow-up.
