In simple words: Ovarian cancer is when abnormal cells in your ovaries grow out of control.It can be hard to detect early because it often doesn't cause noticeable symptoms until it has spread.Symptoms can include bloating, pelvic pain, feeling full quickly, and changes in bathroom habits. Treatment usually involves surgery, chemotherapy, and sometimes other therapies like targeted therapy or hormone therapy.

Malignant neoplasm of the ovary, a small reproductive gland located on either side of the uterus where eggs are produced. This indicates abnormal growth of ovarian cells that can spread to nearby tissues, blood vessels, or lymphatic vessels.

Example 1: A 60-year-old female presents with abdominal bloating, pelvic pain, and early satiety. After a thorough examination and imaging studies, a diagnosis of malignant neoplasm of the ovary is confirmed., A 45-year-old female with a family history of ovarian cancer undergoes genetic testing, which reveals a BRCA1 mutation.She opts for prophylactic bilateral salpingo-oophorectomy, and pathology reveals an early-stage malignant neoplasm of the ovary., A 70-year-old female presents with recurrent abdominal pain and ascites.She has a history of ovarian cancer treated with surgery and chemotherapy five years prior.Imaging reveals peritoneal carcinomatosis, consistent with recurrent malignant neoplasm of the ovary.

Documentation should include details of the patient's presenting symptoms, physical examination findings, imaging studies (ultrasound, CT, MRI), pathology reports confirming the diagnosis, surgical reports (if applicable), and treatment plans.Information regarding family history, genetic testing, and CA-125 levels should also be documented.

** If the neoplasm overlaps contiguous sites, use code C56.8. For multiple non-contiguous tumors of the same site, code each site separately.
