Vulvar cancer is relatively rare. If there is vulvar cancer, most of them are squamous cell carcinoma, and occasionally there are rare cases of vulvar melanoma and vulvar basal cell carcinoma. Regardless of the type, the tumor is prone to rupture, and infection. In advanced stage, the first symptom is local ulceration and pain, and the ulceration and pain will be in the vulva, which looks very swollen and has strong pain when slightly stimulated. If the rectum is pressed backward, there will be difficulty in defecation. In addition, in advanced stage, vulvar cancer will mostly have enlarged lymph nodes on one or both sides of the groin, which will cause some lumps to be felt in the groin area, and the enlarged lumps will sometimes lead to edema, swelling and pain in the lower limbs. If unfortunately there are metastases in internal organs and other organs, the corresponding organs will also show symptoms, for example, multiple metastases in liver will lead to pain in the right side of abdomen and even jaundice, depending on the metastasis site.
