Endometrial Cancer: Symptoms, Treatment Options & Precautions

1. Recognizing the Symptoms: Bleeding & Discharge Warning Signs

Knowing what constitutes abnormal bleeding is your first line of defense. Consult a doctor immediately if you experience:

• Postmenopausal Bleeding: Any bleeding, spotting, or pinkish discharge after you have gone through menopause (even if it only happens once). This is the most common symptom of endometrial cancer.
• Abnormal Cycles (Premenopausal): Bleeding between periods (spotting), unusually heavy periods, or menstrual bleeding that lasts significantly longer than your normal baseline.
• Unusual Discharge: Continuous watery, white, or blood-tinged discharge that may have an unusual odor.
• Pelvic Pain & Discomfort: Persistent cramping or pressure in the lower abdomen or pelvic region.
• Urinary & Intercourse Pain: Pain or difficulty during urination (dysuria), or pain during sexual intercourse (dyspareunia).

2. Risk Factors & Estrogen Excess

Most cases of endometrial cancer are driven by an imbalance between the hormones estrogen and progesterone. When estrogen levels are elevated without enough progesterone to balance it, it is known as "unopposed estrogen":

• Obesity: Fat tissue converts other hormones into estrogen. Consequently, being overweight increases blood estrogen levels, making obesity a key risk factor for uterine lining mutations.
• Estrogen Therapy: Taking estrogen-only hormone replacement therapy (HRT) post-menopause (without progesterone) stimulates lining growth, raising risks.
• Ovulation History: Conditions that cause irregular cycles or lack of ovulation (like Polycystic Ovary Syndrome - PCOS), never having been pregnant, early menstruation (before 12), or late menopause (after 55) increase lifetime estrogen exposure.
• Tamoxifen: A drug used to treat or prevent breast cancer. While it blocks estrogen in breast tissue, it acts like estrogen in the uterus, potentially stimulating the endometrium.
• Genetics (Lynch Syndrome): An inherited genetic condition that increases the risk of colon and other cancers, including endometrial cancer.

3. Screening & Diagnostic Pathways

There is no routine screening test for endometrial cancer (a Pap test does not reliably check the uterus). Diagnostics rely on symptoms and targeted exams:

4. Modern Treatment Options: Surgery, Radiation & Hormones

Because most endometrial cancers are caught early, treatment is highly surgical and often curative:

1. Surgical Removal (Total Hysterectomy & BSO): The standard surgery is to remove the uterus, cervix, fallopian tubes, and both ovaries (since ovaries produce estrogen). Pelvic lymph nodes are often biopsied to confirm the cancer hasn't spread.
2. Radiation Therapy: Often recommended after surgery (adjuvant) to destroy any remaining microscopic cancer cells:
   • External Beam Radiation: Targets the pelvis from an outside machine.
   • Vaginal Brachytherapy: Placing a small cylinder containing radioactive material inside the vagina for brief sessions. This targets the surgical cuff area with minimal side effects to surrounding organs.
3. Hormone Therapy (Progestins): Used for advanced or recurrent endometrial cancers. Progesterone-like drugs slow the growth of endometrial cancer cells by blocking the stimulative effects of estrogen.
4. Chemotherapy & Immunotherapy: Utilized for aggressive cell types (such as uterine serous carcinoma) or if the cancer has spread beyond the pelvis.
