Vulval cancer is a very rare disease and, on average, a GP will only see a new case once every seven years. 85% of cancers of the vulva are squamous and the remaining are of various histological types, including melanomas. The labium majorum is the most common site of involvement and accounts for about 50% of cases. The labium minorum accounts for about 20% of cases. The clitoris and Bartholin's glands are less frequently involved. Usually it spreads slowly, locally and metastasises to groin nodes and from there to pelvic nodes.
