Vulvar tumor is not necessarily vulvar cancer. Benign tumors are less common and usually asymptomatic, while a few of them may break and bleed due to repeated friction on the surface of the lump. The vulva is the outermost part of the female reproductive system, so it is easy to detect lumps in the vulva. Once a lump is found, the patient should go to the hospital as soon as possible and have the lump biopsied to determine whether it is benign or malignant. The diagnosis of benign tumor can be removed. Most malignant tumors occur in postmenopausal women, accounting for about 5% of malignant tumors in female reproductive system. Among vulvar cancers, squamous cell carcinoma is the most common, while others include malignant melanoma of vulva and basal cell carcinoma of vulva. Squamous cell carcinoma of vulva is associated with HPV infection, and the most common site is the labia majora, followed by the labia minora, clitoris and perineum. The most common manifestation of squamous cell carcinoma of vulva is itchy vulva and various forms of lumps even after prolonged treatment, and the lumps gradually grow and become infected, ruptured, oozing fluid and painful. The main symptoms of vulvar melanoma are vulvar itching, bleeding, and increase in the scope of vulvar pigmentation, and early treatment is recommended.
