I had an u/s last week and was told I have a 5cm septated ovarian cyst on my left ovary. I have had 3 cysts in the last 6 months. They did a laproscopy in May and just found another cyst. From what I understand all these cysts were smaller and all but one burst on their own. I also just finished my last period and it was longer and much heavier than normal. I had to go into the hospital b/c I was bleeding extremely heavy. My doctor did the u/s b/c of the bleeding and found this cyst. My doctor wants to do another u/s in 2 months unless I have heavy bleeding this next period or severe abdominal pain, then he will do the u/s sooner. He is concerned of cancer. Is that jumping the gun? I read that 95% of cysts are benign but what about the % of septated cysts. The reading I have done online linked my kind of cysts with cancer. I am just trying to get an idea of what we are looking at...surgery, hysterectomy..etc. Thanks for you help! Also today I have been experiencing pressure in my abdomin as well as lower back pain. It is uncomfortable to sit or stand. When I lay down I can't find any position that isn't uncomfortable. I am wondering if this is related to the cyst.
