I would recommend discussing this with your OB GYN doctor
. Whenever there is a cyst in an ovary, the main concern is making sure that it is not an ovarian cancer. The first step in determining this is almost always an ultrasound, like the one you have had. There are several features of a cyst on an ultrasound that are unlikely to be cancerous, whereas there are other features that are more likely to be concerning.
Since I don't have your ultrasound report to look at, it is hard to be very specific or definitive. However, I do note that the report suggest a likely hemorrhagic cyst. To me, this means that the radiologist
probably saw some features of a benign cyst (hemorrhagic cysts are benign), and I suspect this means that you do not have to be too worried. However, I cannot say this definitively without seeing the whole report. If this is just a likely hemorrhagic cyst, then most doctors
would just order a repeat ultrasound in a month or two to document that the cyst is shrinking and going away.
Again, I would recommend discussing this with your OB GYN doctor so that you can get more specific advice about what the ultrasound means and what, if anything, you need to do next.
