According to research, women with poor oral health or gum disease are 11 times more likely to be diagnosed with breast cancer. The high risk is in part due to inflammation caused by gum disease, which allows bacteria and viruses to enter the blood stream, causing the body to be more vulnerable to other threats.

As the body works hard to fight off the microbes, all the work can bring the body’s immune response down. It can also contribute to abnormal cell changes, resulting in certain cancers, including breast cancer. 

Inflamed, red and soar gums should never be ignored. These are symptoms of gum disease. The dental community recommends that everyone should see a dentist for regular checkups at least twice a year to prevent gum disease, especially with the presence of cancer.

 Research indicates that chronic periodontal disease indicated by missing molars seemed to be associated statistically with breast cancer.

Due to poor oral hygiene and gram-negative anerobic bacterial infection, chronic periodontitis is closely associated with Cytomegalovirus sand Epstein-Barr virus co-infection. It is supposed that these viruses act together to control immune response to bacterial challenges; these viruses and bacteria act together to lead to low-degree chronic inflammation and carcinogenesis. Periodontal disease is associated with an increased production of reactive oxygen species which, if not buffered sufficiently, cause damage to the host cells and tissues. The products of the oral inflammation enter the bloodstream, which may enhance cellular proliferation and mutations, allowing for the development and spread of cancer.
