Pap Smear Test: Procedure, Purpose, and Importance for Women's Health

What Is a Pap Smear?

A screening test that collects cervical cells to detect precancerous changes or cervical cancer. Performed during a pelvic exam using a speculum and brush/spatula.

Why It's Essential

1. Early Cancer Detection – Identifies abnormal cells before invasion; dramatically improves cure rates.
2. Precancerous Detection – Finds cervical intraepithelial neoplasia (CIN), allowing treatment to prevent cancer.
3. Treatment Monitoring – Tracks regression/persistence after therapy for CIN or cancer.

Guidelines (USPSTF)

• Age 21–29: Pap every 3 years.
• Age 30–65: Pap + HPV co-testing every 5 years, or Pap alone every 3 years.
• Stop at 65 if adequate prior screening and no high-risk history.

Impact

Widespread screening has reduced cervical cancer incidence and mortality by >70% in screened populations.
