15 Symptoms of Vulvar Cancer

3. Patches on the Skin

When vulvar cancer is caused by melanoma, a woman may notice dark spots on the skin of the vulva, usually black or dark brown, though they may also appear white, pink, or red. The patches may be evenly distributed throughout the vulva, though they are most often seen around the clitoris, labia majora, and labia minora. To determine if a patch or mole is cancerous, use the ABCDE rule to distinguish between benign and malignant spots: asymmetry, border irregularity, color, diameter, and evolving size or shape.
