Perineal cysts refer to tumors that grow on the female vulva and are cystic tumors, mostly in the area of the vaginal opening. It is caused by long-term staying up late, fire and excess heat and dampness in the body. The cyst will have painful symptoms, and the cystic mass will grow slowly and will be combined with pathogenic infections during the growth process. Perineal cysts are also related to the long-term wearing of tight underwear. Wearing too tight underwear will affect the blood circulation in the perineum, and long-term sitting and lying and lack of exercise also lead to cysts in the perineum. Cystic swellings are benign, due to the inconvenient location it is recommended that it is best to standardize the treatment, keep dynamic observation and suggest surgery when it affects daily life.
