What are the chances bacterial vaginosis causes cervicitis and causes cervical cancer?

Low and zero: Cervicitis is often unexplained but folks have looked at the various risk factors and bacterial vaginosis isn't up there, so i doubt it. To cause cancer, something has to actually get into the genes or greatly accelerate turnover and "bv" just isn't going to do this, statistical link or no. Stop worrying. Cervicitis we can treat; cervical cancer we can prevent / treat with due vigilance.
