The pancreas is a large organ inside the abdomen that secretes juices that help digest food, and also produces the hormone insulin which regulates the sugar levels in yhe blood. Cancers of the pancreas occur particularly among men between ages 35 and 70 years and are over 3 times more common in smokers compared to non-smokers. It is possible that it is linked to chemicals that encourage cancers (carcinogens) that are breathed in or otherwise absorbed and then excreted by the pancreas. Tobacco contains many carcinogens.
Pancreas cancer caused 0.4% of all deaths worldwide in 2002, an average of 37 deaths per million people per year and 3% of all deaths from cancer.
