Cervical cancer

HPV 16 & 18 (squamous cell mostly)

Overview

Cervical malignancy driven by persistent high-risk HPV (16/18), commonly squamous cell. Largely preventable through HPV vaccination and screening; presents with post-coital, intermenstrual or postmenopausal bleeding.

Recognise

  • Post-coital, intermenstrual or postmenopausal bleeding; offensive discharge
  • Advanced: pelvic pain, hydronephrosis, leg oedema, fistula
  • Irregular/friable cervix or visible lesion on speculum

Red flags

  • Any abnormal bleeding with an abnormal-looking cervix → urgent colposcopy/referral, NOT wait for screening

Differentials & how to tell them apart

Cervical ectropionbenign symmetrical red ring, screening normal
Cervical polypbenign pedunculated lesion
Endometrial cancerPMB, endometrial thickening/biopsy
Cervicitisinfective, NAAT

Investigations

Visible lesion → urgent referral for colposcopy and biopsy (do not rely on a smear). Staging: examination, MRI pelvis, CT.

Management

Stage-directed treatment (surgery for early; chemoradiation for advanced)

  1. 1Refer any suspicious cervix urgently for colposcopy + biopsy. Early disease: cone/trachelectomy (fertility-sparing) or hysterectomy.
  2. 2Locally advanced: chemoradiotherapy. Prevention: HPV vaccination + screening.
Surgery / chemoradiationstage-dependent (cone/trachelectomy/hysterectomy; chemoradiation for advanced)

Key points

HPV vaccination (Gardasil 9) and HPV-primary screening have made this largely preventable. A visible lesion is referred directly — a normal smear does not exclude cancer.

Monitor & prognosis

Post-treatment surveillance; fertility implications.

Excellent if early; poorer once locally advanced.
