Periodental Disease and Breast Cancer

Studying the associations

Publish date:: January 5, 2016

Periodontal disease was associated with increased risk of postmenopausal breast cancer, particularly among former smokers who quit in the past 20 years, according to a study of 73,737 women without previous breast cancer. Researchers found:

• 2,124 incident, invasive breast cancer cases were identified after mean follow-up of 6.7 years.

• Periodental disease, reported in 26.1% of women, was associated with increased breast cancer risk, particularly among former smokers who quit within 20 years.

• Among current smokers, the trend was similar.

• The population attributable fraction was 12.06% for periodontal disease among former smokers quitting within 20 years and 10.90% for periodontal disease among current smokers.
