9 REASONS SENIOR DENTAL HEALTH CARE IS IMPORTANT
This is disturbing! Read the study below and thank you for visiting Surrey Endodontic Centre.
!Jo L. Freudenheim, PhD, and colleagues monitored 73,737 postmenopausal women enrolled in the Women’s Health Initiative Observational Study, none of whom had previous breast cancer. Periodontal disease was reported in 26.1 percent of the women. Because prior studies have shown that the effects of periodontal disease vary depending on whether a person smokes, researchers examined the associations stratified by smoking status.
After a mean follow-up time of 6.7 years, 2,124 women were diagnosed with breast cancer. The researchers found that among all women, the risk of breast cancer was 14 percent higher in women who had periodontal disease.
Among women who had quit smoking within the past 20 years, those with periodontal disease had a 36 percent higher risk of breast cancer. Women who were smoking at the time of this study had a 32 percent higher risk if they had periodontal disease, but the association was not statistically significant. Those who had never smoked and had quit more than 20 years ago had a 6 percent and 8 percent increased risk, respectively, if they had periodontal disease.
“We know that the bacteria in the mouths of current and former smokers who quit recently are different from those in the mouths of non-smokers,” Freudenheim explained. One possible explanation for the link between periodontal disease and breast cancer is that those bacteria enter the body’s circulation and ultimately affect breast tissue. However, further studies are needed to establish a causal link, Freudenheim said.
