The seriousness of pelvic cysts is generally not about its size, but more about its benignity and complications. 1. benign and malignant: most pelvic cysts are benign, such as ovarian chocolate cysts, ovarian cystadenoma, pelvic inflammatory masses, etc., which do not pose a life-threatening threat to the body, so they are not considered to be serious, but there are a small number of pelvic cysts belonging to the malignant masses, which are more serious at this time. It is recommended to consult a doctor in time to clarify the nature of the cyst. 2. Complications: If the pelvic cyst is simple, it is generally not serious; if the pelvic cyst is combined with sepsis, peritonitis, tubal abscess and other complications, it will be tricky to deal with, and the after-effects will be more obvious, and it may also affect women’s fertility, which is relatively serious at this time. Therefore, in order to determine the severity of pelvic cysts, we should consult a doctor in time to find out the nature of the cysts, and also pay attention to the presence of fever, abdominal pain and other symptoms in time, to avoid the aggravation of pelvic cyst infection.
