Itching of vulva during radiotherapy for cervical cancer is a relatively common side effect, which is probably divided into the following two aspects: 1. vulvovaginitis, the vulva is a relatively humid place, and after radiation stimulation and the influence of secretions, local acute, radioactive skin mucosal damage may occur. At this time, local ventilation, dryness and cleanliness should be maintained to promote wound healing. 2. During radiotherapy, the vagina is within the range of the radiation field, and intracavitary irradiation may cause damage, thus causing radioactive vaginitis, and if accompanied by infection, vulvar itching will appear. This is the time to keep local cleanliness and regular vaginal douching to promote wound healing and discharge of secretions to further reduce the occurrence of vaginal adhesions.
