Pancreatic cancer occurs when there is out-of-control cell growth in the pancreas. The cells continue dividing and form lumps called tumors, which interfere with the normal functioning of the pancreas.
Studies have found positive associations between gum and bone disease and pancreatic cancer. In one study, men with a history of gum disease had a 63% higher risk of developing pancreatic cancer than those with no history of gum disease. People with chronic inflammation caused by gum disease harbor higher levels of harmful bacteria in the mouth and gut. Over many years, this can lead to higher amounts of cancer-causing nitrosamines.
