Some vulvar cancers will have lumps or ulcers at the site of the lesion that are visible to the naked eye. However, since the lumps are not specific, so the lumps visible to the naked eye in the vulva cannot confirm the diagnosis of vulvar cancer. It is suggested that if there is any abnormality, one should go to the hospital for ultrasound, gynecological examination and pathology examination to clarify the cause of the disease and then give appropriate treatment. Vulvar cancer refers to malignant tumors originating from the vulva, of which squamous cell carcinoma belongs to the most common pathological type, and others include malignant melanoma, basal cell tumor and sarcoma. For vulvar squamous cell carcinoma, patients may have localized lumps or ulcers visible to the naked eye in the labia majora, labia minora, clitoris and other parts of the vulva, often accompanied by vulvar itching; for vulvar malignant melanoma, patients may have nodular growths and pigmented foci visible to the naked eye around the labia minora, clitoris, etc., accompanied by or not accompanied by ulcers. In addition, some benign vulvar tumors such as vulvar papilloma can also present with vulvar masses as well as ulcers, making it difficult to make a differential diagnosis of vulvar cancer based on clinical presentation. If you find any lesions or discomfort in the vulva, it is recommended to go to the hospital as soon as possible for a clear diagnosis and standardized treatment under the guidance of the doctor.
