although by the looks of it,it does not look malignant but considering the age get a CT-MRI done and serum ca 125 done and let us know
Next Steps
Surgery is indicated
simple Hysterectomy with bilateral removal of ovaries and fallopian tubes -if ovarian cyst comes out to be normal
Radical Hysterectomy (wider excision)is done if malignancy is suspected
In our settings in such a case we do a frozen biopsy sampling at the time of surgery and accordingly proceed for surgery
