Carcinomas of gynaecology

Reading File
“Carcinomas of gynaecology” is a broad topic. A useful study map is:
  1. Cervical carcinoma
    • HPV-related pathogenesis, screening, staging, treatment, prevention
  2. Endometrial (uterine corpus) carcinoma
    • Type/classification, risk factors, molecular groups, presentation, staging, management
  3. Ovarian carcinoma
    • Epithelial, germ-cell, and sex cord-stromal tumours; spread, diagnosis, cytoreduction, systemic therapy
  4. Vulval carcinoma
    • HPV-associated and HPV-independent pathways, clinical presentation, nodal evaluation, treatment
  5. Vaginal carcinoma
    • Primary versus secondary tumours, risk factors, staging and radiotherapy-focused management
  6. Gestational trophoblastic neoplasia
    • Invasive mole and choriocarcinoma, hCG surveillance, FIGO risk scoring, chemotherapy
  7. Principles shared across cancers
    • FIGO staging, lymph-node assessment, fertility-sparing options, radiotherapy, chemotherapy, targeted and immunotherapies, surveillance.
At a high level, cervical cancer is largely preventable through HPV vaccination and screening; endometrial cancer commonly presents early with postmenopausal bleeding; and ovarian cancer often presents late because symptoms are nonspecific and disease disseminates intraperitoneally. Vulval and vaginal cancers are less common, while gestational trophoblastic neoplasia is unusually chemosensitive.
Which topic should I cover in detail: cervical, endometrial, ovarian, vulval/vaginal, GTN, or a concise comparison table of all?

endometrial polyps ACOG management postmenopausal bleeding hysteroscopy

An 18 mm polyp is 1.8 cm. If this refers to an endometrial polyp (inside the uterus), size alone does not mean cancer. Most are benign, but the appropriate next step depends mainly on:
  • Age and menopausal status
  • Bleeding, especially postmenopausal bleeding or persistent irregular bleeding
  • Risk factors such as obesity, tamoxifen use, diabetes, hypertension, or a past/family history of endometrial cancer
  • Ultrasound appearance and endometrial thickness
Usual approach
  • Premenopausal with no symptoms: observation can sometimes be reasonable, although an 18 mm polyp is relatively large and a gynecology review is appropriate.
  • Abnormal bleeding, infertility, or postmenopausal status: hysteroscopy with removal of the polyp and histopathology is commonly advised. Hysteroscopy directly visualizes the lesion and permits targeted removal/biopsy. The ACOG guidance on postmenopausal bleeding advises further assessment, including hysteroscopy, for persistent or recurrent bleeding when initial sampling is negative.
Seek prompt gynecologic assessment if you are postmenopausal and bleeding, have heavy bleeding, anemia symptoms, or pelvic pain. Seek emergency care for very heavy bleeding, fainting, severe pain, or pregnancy-related bleeding.
If you share whether it is an endometrial or cervical polyp, your age/menopause status, and whether you have bleeding, I can explain what an 18 mm result usually means in that setting.

ACOG postmenopausal bleeding endometrial thickness 4 mm transvaginal ultrasound

An endometrial thickness of 8 mm, together with a 1.8 cm endometrial polyp, needs gynecologist review but does not by itself diagnose cancer. A polyp can itself make the measured lining appear thicker.

What 8 mm means depends on menopause status

SituationMeaning of 8 mm
Postmenopausal with bleeding or spottingAbnormal and should be assessed promptly with endometrial tissue sampling, usually hysteroscopy and removal/biopsy of the polyp.
Postmenopausal without bleedingNot an emergency, but the 18 mm polyp plus 8 mm lining warrants a gynecology appointment to decide on hysteroscopic removal and histology, particularly with risk factors.
Still having periodsThickness naturally changes through the menstrual cycle, so 8 mm may be normal. The polyp and symptoms guide management more than the thickness alone.
After menopause, any bleeding or spotting needs assessment. Traditional ultrasound triage considered a lining of 4 mm or less reassuring in postmenopausal bleeding, but ACOG's updated 2026 guidance recommends ultrasound plus tissue sampling in most patients with postmenopausal bleeding.
Given the 18 mm polyp, the usual definitive test and treatment is hysteroscopy with polypectomy, with the removed tissue sent for histopathology. A blind biopsy can miss a focal polyp, so direct visualization is often preferred when a polyp is seen.
Arrange prompt review, especially if you are postmenopausal, have bleeding, obesity, diabetes, hypertension, or take tamoxifen. Seek urgent care for very heavy bleeding, dizziness/fainting, severe pain, or pregnancy-related bleeding.
