Pap Smear Guidelines by Age: When to Start, How Often, and When to Stop + Understanding Abnormal Pap Smear Results

Cervical cancer is one of the most preventable types of cancer, thanks to routine screening through Pap smears. Despite this, many women still remain unaware of when to start getting tested, how frequently to go, and what abnormal results mean. In this comprehensive guide, we delve into Pap smear guidelines by age, frequency recommendations, and a professional overview of abnormal Pap smear results,  provided by Dr. Shweta Bansal Wazir, a leading obstetrician and gynecologist in Gurgaon.

What Is a Pap Smear and Why Is It Important?

A Pap smear (Papanicolaou test) is a screening procedure for cervical cancer. It involves collecting cells from the cervix to detect any abnormalities that may lead to cancer. Early identification of pre-cancerous or cancerous cells enables timely intervention and greatly reduces the risk of progression.

According to research published on the National Library of Medicine (PMC), regular cervical screening has decreased the incidence of cervical cancer by more than 50% in countries where programs are actively implemented.

Pap Smear Guidelines by Age: When to Start and How Often

Ages 21 to 29: Begin Screening Early

• Start at Age 21: Regardless of sexual activity, cervical screening should begin at age 21.
• Frequency: Women between 21–29 should undergo a Pap smear once every 3 years if results are normal.
• HPV Testing: Routine HPV (human papillomavirus) testing is not recommended in this age group unless Pap smear results are abnormal.
  
  

Ages 30 to 65: Combine Tests for Better Accuracy

• Pap Smear + HPV Co-testing (Preferred Method): Conducted every 5 years if both tests are negative.
• Alternative: A Pap smear alone every 3 years is also acceptable.
• This age range benefits most from co-testing as persistent HPV infection is the leading cause of cervical cancer.
  
  

Age 65 and Above: When to Stop

• Women over 65 may stop Pap smear screening if:
  
  
  • They’ve had three consecutive negative Pap tests or two negative HPV co-tests in the last 10 years.
  • They have no history of cervical pre-cancer (CIN2 or higher) in the past 20 years.
    
    
• However, if a woman has risk factors (like previous abnormal results, HIV infection, or compromised immunity), continued screening may be necessary.
  
  

“Routine screening, when followed correctly, provides the highest chance of preventing cervical cancer or catching it at a very early, treatable stage.”  Dr. Shweta Bansal Wazir

 What Happens During a Pap Smear?

• The patient lies on an examination table with feet placed in stirrups.
• A speculum is gently inserted to visualize the cervix.
• A soft brush or spatula is used to collect cervical cells.
• Cells are transferred into a vial for liquid-based cytology (LBC)  a, technique that has significantly reduced inadequate results.
  
  

The test takes less than 5 minutes and might feel slightly uncomfortable but should not be painful.

Understanding Abnormal Pap Smear Results

Receiving abnormal results doesn’t mean you have cancer. Here’s what the results can mean:

1. ASC-US (Atypical Squamous Cells of Undetermined Significance)

• Most common abnormal finding.
• Indicates slight changes in cervical cells.
• Often caused by HPV infection, which may resolve naturally.
• Next step: Repeat Pap or perform HPV testing.
  
  

2. LSIL (Low-Grade Squamous Intraepithelial Lesion)

• Mild cell changes, usually due to HPV.
• May regress without treatment, especially in younger women.
• Follow-up: Repeat test in 12 months or colposcopy (a detailed cervical exam).
  
  

3. HSIL (High-Grade Squamous Intraepithelial Lesion)

• Indicates more significant abnormalities with higher risk of progressing to cancer.
• Colposcopy and biopsy are often recommended.
  
  

4. AGC (Atypical Glandular Cells)

• These involve changes in the cells lining the cervical canal.
• May require more detailed investigations, including endometrial sampling.
  
  

5. ASC-H or AIS (Adenocarcinoma In Situ)

• Pre-cancerous lesions.
• Immediate colposcopy and treatment are required.
  
  

“An abnormal Pap smear should never be ignored, but it’s also not a cause for panic. Most changes are manageable, especially when detected early.”  Dr. Shweta Bansal Wazir

What Is a Colposcopy?

If a Pap smear reveals abnormalities, a colposcopy may be recommended.

• A magnifying instrument is used to examine the cervix more closely.
• Acetic acid (vinegar solution) is applied to highlight abnormal areas.
• A biopsy may be taken for further testing.
  
  

The procedure is simple, usually painless, and done in-clinic.

When Should Screening Be More Frequent?

Certain high-risk women may need more frequent screening:

• HIV-positive patients
• Women with immunocompromised status
• History of cervical dysplasia or cancer
• Exposure to DES (diethylstilbestrol) in utero
  
  

These women should consult with a gynecologist for a personalized screening schedule.

What You Can Do to Protect Your Cervical Health

• Get vaccinated: The HPV vaccine (Gardasil 9) protects against the most common cancer-causing strains.
• Use protection: Safe sex reduces HPV transmission.
• Avoid smoking: Tobacco impairs immune response, increasing cancer risk.
• Don’t skip appointments: Attend regular screening even if you feel healthy.
