How does your doc tell if it's a vaginal cancer or just a benign tumor?

Examination & biopsy: Sometimes, clinical appearance of benign tumor is different than cancer-and that will give you some hints that perhaps it is not a cancer. However, biopsy of the lesion is the only thing that can tell you definitively whether it is a benign tumor or cancer. Discuss with your gynecologist.

Vaginal cancer: Biopsy - sent to pathology to get actual diagnosis.
