Causes of Pancreatic Cancer

Causes of Pancreatic Cancer
Although the exact cause of pancreatic cancer is not known, smoking is the main risk factor, with smokers 2-3 times more likely to have the disease than nonsmokers. Age is also related, with the disease usually striking after age 45.  Diabetes is also linked to pancreatic cancer, with about 10-20% of those diagnosed with the cancer having diabetes. Other risks include chronic pancreatitis and cirrhosis of the liver. And family history of pancreatic cancer, high fat diet, obesity, and lack of exercise can also play a part.

Symptoms of Pancreatic Cancer

Symptoms of Pancreatic Cancer
Pancreatic cancer is called a "silent" disease because symptoms typically do not present in the early stages. But as the cancer grows and spreads, pain often develops in the upper abdomen and sometimes spreads to the back. The pain may become worse after the person eats or lies down. Other symptoms may include jaundice, nausea, loss of appetite, weight loss, fatigue, weakness, and depression.
