What causes vulvar cancer?

Vulvar cancer is a common malignant tumor with an increasing incidence rate. There are many causes of the disease. Changes in eating habits, endocrine disorders, and chaotic sexual life may lead to vulvar cancer. Vulvar cancer needs to be treated in time to avoid delaying the best treatment time. It can be treated with surgery and radiotherapy. After surgery, you must recover under the guidance of a doctor. Avoiding bad living habits can help prevent vulvar cancer.

Vulvar malignant tumors are mainly primary, accounting for about 4% of female genital tumors and 1% to 2% of all tumors in women. The vast majority of vulvar cancers are squamous cell carcinomas, accounting for about 95% of vulvar malignant tumors. The average age of onset is 50 to 60 years old, and it may also occur before the age of 40. Adenocarcinoma is less common. Sometimes vulvar cancer is confined to the epithelium. When it spreads within the epithelium, it is called carcinoma in situ, also known as vulvar epithelial cancer. There are two types of epithelial cancer: ① squamous cell carcinoma in situ (also known as Bowen's disease); ② eczematous intraepithelial carcinoma (also known as Paget's disease). In addition, there are basal cell carcinoma and malignant melanoma.

What factors are associated with vulvar cancer?

1. Vulvar infection: such as sexually transmitted diseases, viruses, bacteria, Trichomonas, fungi, etc., and vulvitis caused by menstruation. The vulva is the primary and most common site of onset.

2. Mechanical stimulation: such as bad hygiene habits, dirt on the vulva, tight underwear, sweat stimulation, etc.

3. Allergic vulvitis: allergic dermatitis caused by detergents, cosmetics, condoms and medical devices.

4. Foreign bodies in the vagina: Long-term placement of a pessary may cause foreign bodies to remain in the vagina and infect and irritate the vulva, resulting in swelling and pain.

5. Stimulation by urine and feces: stimulation by diabetes in patients with urinary diseases, fecal contamination, and diabetes.

6. Systemic diseases: diabetes, systemic lupus erythematosus, papular psoriasis, etc.

7. Malignant tumors of the vulva: vulvar cancer, vaginal cancer, etc.

8. External Bartholin gland abscess.

9. Unexplained vulvar pain: swelling and pain in the vulvar vestibule accompanied by frequent urination, urgency, and diabetic syndrome. The pathogenesis is unclear.

10. Hematoma after trauma can also cause more severe swelling and pain.

Knowing what vulvar cancer is and its causes, we can prevent it through its causes. Prevention is worse than cure. As long as we can prevent the disease, we can reduce the incidence of the disease.
