Pelvic cysts are usually benign more often than not. Usually pelvic masses originate mainly from the pelvic reproductive organs, such as the ovaries, uterus, fallopian tubes and other organs or tissues, such as the appendix, rectum, bladder, and retroperitoneal tissues. Generally, cysts are benign and most are not serious. The severity of cysts is generally related to the location, size, hardness, mobility, degree of pressure and pain, and the relationship between the mass and the surrounding tissues, which is important for clinical treatment and judging the prognosis of the disease. Therefore, whether a pelvic cyst is serious or not depends on the size of the cyst, the mobility of the cyst and whether the surrounding tissues are under pressure. Patients with pelvic cysts should actively consult a doctor and under the guidance of a professional doctor for relevant examinations and treatments.
