Ovarian cancer begins in the ovaries, which produce eggs and hormones. It is the deadliest gynecologic cancer, often diagnosed at a late stage. Ovarian cancers are classified into:
- Epithelial tumors (most common)
- Germ cell tumors (develop from egg-producing cells)
- Stromal tumors (develop from hormone-producing tissue)

- Pelvic or abdominal pain
- Difficulty eating or feeling full quickly
- Frequent urination
- Fatigue, back pain, or menstrual changes
病因与风险因素
- Age (especially after menopause)
- Family history of ovarian, breast, or colorectal cancer
- BRCA1 and BRCA2 gene mutations
- Endometriosis
- Never having been pregnant
诊断方法
- Pelvic exam
- Transvaginal ultrasound
- CA-125 blood test (tumor marker)
- CT or MRI
- Surgical exploration and biopsy
治疗方案
- Surgery (hysterectomy and removal of ovaries/tumor)
- Chemotherapy (platinum-based regimens)
- Targeted therapy (e.g., PARP inhibitors)
- Hormonal therapy (for low-grade tumors)
- Clinical trials (for advanced/recurrent cases)

- Depends on cancer stage and type
- 5-year survival rate:
- Localized: ~93%
- Advanced stage: ~30%
