Some causes of pancreatic cancer

Nowadays, there are many people suffering from pancreatic cancer, so we should do a good job in preventing pancreatic cancer. So, what are the causes of pancreatic cancer ? Regarding this issue, let's ask experts to introduce to you the causes of pancreatic cancer.

1. Chronic pancreatitis, a cause of pancreatic cancer: All types of chronic pancreatitis can develop into pancreatic cancer. The risk of developing pancreatic cancer from chronic pancreatitis accumulates by 2% every 10 years, and the risk is higher for older patients than for younger ones. The peak age of pancreatic cancer is 10 to 20 years after the onset of chronic pancreatitis. Smoking can double the risk of hereditary pancreatitis patients and advance the onset of the disease by 20 years.

2. Smoking: Smokers have a 3-fold increased risk of pancreatic cancer compared to non-smokers, and those who smoke ≥25 cigarettes a day are 4 times more likely to smoke than non-smokers. For lifelong smokers, the more they smoke in the last 15 years of their lives, the greater their risk of pancreatic cancer. Studies have shown that not only active smoking is the cause of pancreatic cancer, but passive smoking is also related to the onset of pancreatic cancer. However, after quitting smoking for 10 years, the incidence of pancreatic cancer can be reduced to the normal level.

3. Genetic factors: Studies have found that 7.8% of pancreatic cancer cases have a family history, while the control group has only 0.6%; in families with 2 or more cases of pancreatic cancer, the relative risk of first-degree relatives (parents, siblings, children) developing pancreatic cancer is about 18, while for families with 3 or more cases, it is as high as 57. The risk of pancreatic cancer in first-degree relatives of pancreatic cancer is 3 to 5 times higher than that of the normal population, and smokers have an 8-fold increase. This is one of the causes of pancreatic cancer.

The above is an introduction to the causes of pancreatic cancer. It is for your reference only. I hope you can do a good job in preventing pancreatic cancer to avoid unexpected consequences. In addition, if you have any questions about the causes of pancreatic cancer, please consult online experts!
