Pancreatic cancer is caused by the abnormal and uncontrolled growth of pancreatic cells.
About half of all new cases are diagnosed in people aged 75 or older, and are rare in people under 40 years of age.
According to the NHS, the causes of pancreatic cancer are not well understood, but a number of risk factors have been identified.
For example, having a history of some health problems such as diabetes may increase the risk.
For example, having a history of some health problems such as diabetes may increase the risk.
Diabetes is a permanent disease that causes the blood sugar level to become too high.
There are two main types of diabetes: type 1 and type 2.
Type 1 diabetes occurs when the immune system attacks and destroys insulin-producing cells.
Type 2 diabetes is when the body does not produce enough insulin or when the body's cells do not react to insulin.
Insulin controls the amount of sugar in the blood.
The link between diabetes and pancreatic cancer is due to the fact that insulin is a hormone produced by the pancreas.
On the contrary, people with pancreatic cancer who do not have diabetes can also develop diabetes because of the disease.
This is because the tumor can stop the production of insulin by the pancreas as it would normally.
Chronic pancreatitis and stomach ulcers are other health problems that may increase the risk of pancreatic cancer.
Chronic pancreatitis is a condition in which the pancreas stops working properly due to permanent inflammation.
It differs from acute pancreatitis where inflammation is only short-lived, but can be caused by repeated episodes of acute pancreatitis.
Pancreatitis is most often caused by excessive consumption of alcohol.
Stomach ulcers, in turn, are open sores that develop on the lining of the stomach.
They occur when the diaper that protects the stomach from stomach acid breaks down and can be caused by infections and taking nonsteroidal anti-inflammatory drugs for a long time at high doses.
Other risk factors for developing pancreatic cancer include overweight and smoking.
About one in three cases is associated with tobacco or chewing tobacco.
In addition, in about one in 10 cases, pancreatic cancer is inherited.
