Types of vulval cancer
- Squamous cell carcinoma.
Most vulval cancers (90%) develop from squamous cells, the skin cells of the vulva. These cancers usually grow very slowly over a few years.
- Vulval melanoma
Vulval melanomas develop from melanin, the cells that produce pigment and give skin its colour. Only about 2–4% of vulval cancers are melanoma.
These are very rare. They develop from cells that line glands in the vulval skin. Paget’s disease of the vulva is a pre-malignant condition in which glandular cells spread outwards and across the vulval skin.
- Verrucous carcinoma.
This rare, very slow-growing type of cancer looks like a large wart.
These are extremely rare. Sarcomas develop from cells in tissue, such as muscle or fat under the skin, and tend to grow more quickly than other types of cancer.
