A precancerous cervical lesion, also known as an intraepithelial lesion, is a change in the cervix's cells that has the potential to turn into cervical cancer. Squamous and glandular cells are the two basic types of cervical cells, and abnormalities can arise in either. The exterior female genital organs, as well as the muscular and elastic tube tract that connects the cervix to the vulva, are represented by the vulva and vagina. Squamous cell tumours are the most prevalent malignancies of these organs, which develop from the surface lining. VIN (vulvar intraepithelial neoplasia) and VIN (vaginal intraepithelial neoplasia) are precursor lesions to both vulvar and vaginal squamous cell malignancies (VAIN). Other cancers, such as melanoma, Bartholin's gland cancers, and basal cell cancers, are much less prevalent. Vulvar cancer can affect any portion of the external organs, however the labia majora and minora are the most commonly affected. Vulva carcinoma is a rare cancer that accounts for only 0.6 percent of all cancers in women, and it develops slowly over several years. Squamous cell carcinomas account for the majority of vulvar malignancies. Melanoma is a kind of vulvar cancer that typically develops in the labia minora or clitoris.
