Hi tliebman...i've been doing some reading on atypical vessels and although I don't want to worry you I would agree with what you've been reading. Atypical vessels seem to be a sign of cervical cancer...these are not present in cervical dysplasia. The fact that your doctor can't even answer your question makes me question her competence. With her knowledge and expertise she should be more concerned and curious of your situation and do some additonal investigating. If I were you i'd get a second opinion. It could very well be you don't have cancer, and I certainly hope you don't, but it could be some other type of condition that also needs to be treated, not simply ignored because the biopsy came back negative. Do you think you could find another doctor for a second opinion? Good luck and keep us posted
