Endometrial (Uterine) Cancer
Overview
Endometrial cancer, also called uterine cancer, originates in the lining of the uterus (endometrium). It is the most common gynecologic cancer in developed countries and is often diagnosed early due to noticeable symptoms like postmenopausal bleeding. The two main types are:
- Type I (Endometrioid): estrogen-dependent, better prognosis
- Type II (Non-endometrioid): includes serous, clear cell; more aggressive
Symptoms
- Abnormal vaginal bleeding (especially after menopause)
- Pelvic pain or pressure
- Pain during intercourse
- Unusual vaginal discharge
Causes & Risk Factors
- Unopposed estrogen exposure (e.g., obesity, hormone therapy)
- Age >50
- Polycystic ovary syndrome (PCOS)
- Never having been pregnant
- Family history or Lynch syndrome
Diagnosis
- Transvaginal ultrasound
- Endometrial biopsy (or dilation and curettage)
- Hysteroscopy
- Imaging (MRI or CT) for staging if needed
Treatment Options
- Surgery: hysterectomy with or without lymph node removal
- Radiation therapy
- Hormonal therapy (progestins for low-grade tumors)
- Chemotherapy (for advanced/recurrent disease)
- Targeted therapy or immunotherapy (in selected cases)
Prognosis
- Excellent when detected early
- 5-year survival rate:
- Localized: ~95%
- Regional: ~69%
- Distant: ~18%
Living with this Cancer Type
- Managing hormonal changes post-surgery
- Sexual health and emotional well-being
- Regular surveillance for recurrence
- Genetic counseling (especially with Lynch syndrome)
Prevention & Screening
- Maintain healthy weight and control estrogen exposure
- Oral contraceptive use may reduce risk
- Screening for high-risk women with Lynch syndrome

Q: Can it be detected early?
A: Yes, due to early symptoms like postmenopausal bleeding.
Q: Is hysterectomy always required?
A: For most, yes. In early-stage or fertility-preserving cases, hormonal therapy may be used.
