Gardnerella vaginalis and breast cancer

Abstract

G. vaginalis was suggested to be an associated factor in carcenogenesis. We have studied 41 breast disease (31 breast cancer and 10 fibrosing adenomatosis) patients for the presence of G. vaginalis by PCR in tumor, blood and saliva. G. vaginalis was detected in 46% of saliva samples, 44% of blood samples, and 56% of tumor; in 85% cases at least one of patient’s samples was found to be G. vaginalis positive. For the first time, a relationship between G. vaginalis and breast disease was shown
