Cytoreductive surgery: Also known as debulking surgery. It aims to remove as much of the visible tumor as possible, including the ovaries, fallopian tubes, uterus (in some cases), and any metastatic lesions in the abdomen and pelvis. This is crucial for improving the effectiveness of subsequent chemotherapy and enhancing the patient's prognosis.

Laparoscopic ovarian cystectomy: For benign ovarian tumors or early - stage ovarian cancers in some carefully selected cases. It's a minimally invasive approach where the cyst or tumor is removed through small incisions in the abdomen using a laparoscope. This helps preserve ovarian function and has a quicker recovery compared to open surgery.
