As the disease progresses, a series of symptoms may appear, such as vaginal bleeding, fluid discharge, pain, and so on. At the earliest stage, the main symptom is contact vaginal bleeding, that is, a small amount of vaginal bleeding after intercourse or gynecological examination. Later on, there may be small, continuous, irregular vaginal bleeding during menstruation or after menopause. If the tumor erodes into the blood vessels, it may cause heavy bleeding and vaginal discharge. If there is a co-infection, the leukorrhea may have a foul odor, and pain may occur when the cancer invades the surrounding tissues and nerves.
