Women with a history of gum disease have up to a 14 percent higher risk of cancer, new research reveals.
Periodontal disease is significantly associated with an increased susceptibility to esophageal and gallbladder cancer in postmenopausal women, a study found.
The researchers believe pathogens from the mouth can easily infect the nearby esophagus and cause cancer.
Inflammation has also previously been associated with both gum disease and tumor development.
The researchers add such findings are particularly important in older people, as their growing life expectancy puts them at a greater risk of periodontal conditions and cancer.

Social cancer patients have better survival prospects than those who do not interact with other sufferers, research revealed last month.
Patients undergoing chemotherapy who socialise with other sufferers have a 68 percent risk of dying within five years, a study found.
This is compared to a 69.5 percent risk if patients are isolated from other sufferers during their treatment, the research adds.
Lead author Jeff Lienert from the National Human Genome Research Institute, said: 'A two percent difference in survival might not sound like a lot, but it's pretty substantial.
'If you saw 5,000 patients in nine years, that two percent improvement would affect 100 people.'
The researchers believe interacting with others during a sufferer's treatment reduces their stress levels, leading to better survival prospects.
