I am a 21 year old female. I was diagnosed with two ovarian cysts that are thought to be cystadenomas back in January of this year. I went into the ER last week because of excruitiating pain and a blood test revealed a high creatinine level. Today I was diagnosed with hydronephrosis and hydroureter via ultrasound with no known obstruction. I have read that hydronephrosis could be a sign of pelvic cancers. Should I be worried about cancer considering I have both the cysts and the hydronephrosis now?
