The incubation period of vulvar cancer varies from individual to individual, depending on the patient’s own physical condition and the type of vulvar cancer, and may be as short as 3-5 years or as long as 10 years or even longer. Vulvar cancer is a malignant tumor of vulva, mostly seen in postmenopausal women, and is often caused by HPV infection or vulvar squamous epithelial lesions. Patients will have different forms of vulvar redundancies, which may be accompanied by pain and itching. The latent period of vulvar cancer refers to the time required for the epithelial tissues of vulva to develop cancer from normal to cancerous, which is a gradual evolutionary process and usually takes several years. In daily life, it is necessary to pay attention to vulvar cleanliness, avoid unclean sex, and have regular health checkups for early detection and timely treatment. If symptoms of vulvar cancer appear, it is recommended to consult a gynecologist in time to clarify the diagnosis and actively cooperate with the doctor for treatment.
