I came across this article today in Oncology News International.  For a long time, a septated ovarian cyst on your ultrasound meant you were having surgery.  The recommendations have now changed.  No longer do doctors need to immediately operate.   It now appears that most of the time, septated cysts are not cancerous.

There are some instances where cancer is more likely.  For example, if there is any solid material in the cyst, then surgery is necessary to test it.  Also, if there are any papillary projections (little finger like areas sticking out), then surgery is done.  Other than that, doctors are advised to watch the cyst on ultrasound.

In a test, 38.8% of these septated ovarian cysts resolved on their own.  10% of them were removed, with none of them being cancerous.

So complex septated ovarian cysts are not necessarily considered complex anymore.  There’s a good chance that it can be treated naturally and go away on its own, without invasive surgery.
