Vulvar cancer is a type of cancer that affects the external genitalia of women, specifically the area known as the vulva. The vulva is the external portion of the female genital organs, and includes the clitoris, labia majora and minora, and the vestibule of the vagina. The most common type of vulvar cancer is squamous cell carcinoma, which accounts for approximately 90% of all cases. Other types of vulvar cancer include melanoma, adenocarcinoma, and sarcoma. The exact cause of vulvar cancer is unknown, but certain factors have been linked to an increased risk. These include chronic inflammation of the vulva, HPV infection, a weakened immune system, smoking, and a history of sexually transmitted infections. Symptoms of vulvar cancer can include itching, burning, and/or pain in the vulvar area, as well as a lump or sore that does not heal. If vulvar cancer is diagnosed, it is important to seek prompt medical treatment. Treatment options may include surgery, radiation therapy, chemotherapy, or a combination of treatments. Surgery is the most common treatment for vulvar cancer, and may involve removing the cancerous cells or the entire vulva. Radiation and chemotherapy are used to kill any remaining cancer cells, and may be used before or after surgery. Vulvar cancer is a serious condition, and early detection is key to successful treatment. Women should be aware of the signs and symptoms, and should see their doctor if they experience any of them. Regular check-ups and screenings are also important, as they can help detect the disease in its earliest stages.
