Tooth loss leads to increased esophageal, head and neck, and lung cancer risk
May 15, 2008
Washington – Now be more cautious about your tooth as recent researches at Japan has established a link between cancer and tooth loss. Tooth loss may lead to cancer of esophagus, head and neck, and lung cancers.
The boffins from Aichi Cancer Center in Nagoya and Nagoya University Graduate School of Medicine said that the bacterial infection and inflammation consequential from poor oral hygiene results in tooth loss eventually may lead to cancer.
“Tooth loss is a common consequence of chronic bacterial infection and may, therefore, serve as a surrogate for chronic infection and inflammation, which in turn may be important to the pathogenesis of cancer,” said Akio Hiraki, Ph.D.
As a part of their study, the scholars measured rates of fourteen different cancers and rates of tooth loss in about 5,240 cancer patients in Japan.
These were then compared with 10,480 matched cancer free partaker.
The studies particularly established that people with tooth loss were 136 % more probable to develop cancer of esophagus, had a 68 % raised risk of developing head and neck cancer and a 54 % greater chance of developing cancer of lung.
The studies also established that the rate of cancer rose proportionally to the number of teeth a patient had lost.
This study come into view in the May issue of Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.
