Gum disease linked to higher cancer risk in women, study finds
Researchers find significantly higher risk of cancers of the oesophagus, breast, lungs and gall bladder, and melanomas, in women with a history of periodontal disease, but more research is needed to find reasons
Women with a history of gum disease face a higher risk of several types of cancer, particularly tumours in the oesophagus and breasts, a US study has found.
“A history of periodontal disease was associated with a 14 per cent higher risk of developing any cancer,” said the study published on Tuesday in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.
“The strongest association was for cancer of the oesophagus, which was more than three times more likely in women with periodontal disease than women.”
Researchers also uncovered a “significantly higher risk” of lung cancer, gallbladder cancer, melanoma and breast cancer.
The study spanned 1999 to 2013, and involved more than 65,000 post-menopausal women who filled out questionnaires about their health. The women, aged 54 to 86, were followed for an average of eight years.
