I'm sorry but how the hell are you supposed to know it's vulvar when it says nothing about the vulva. I was between that and polyps, but put polyps because it was on the perineum? Like how the hell is that the vulva?
Vulvar cancer is rarer than cervical cancer but has many of the same risk factors including HPV. Another risk factor worth knowing is lichen sclerosis, which results in thin itchy vulvar skin.
