Getting an abnormal Pap result can be stressful, especially when the report contains terms such as ASC-US, LSIL, HSIL, or HPV positive. The word "abnormal" can sound alarming, but it does not automatically mean cervical cancer.

A Pap test looks for changes in cervical cells. An HPV test checks for certain high-risk types of human papillomavirus that can contribute to cervical cell changes. Depending on your results and your previous screening history, your health care provider may recommend repeat testing, additional testing, or a closer examination such as a colposcopy.

Understanding the language on your report can make it easier to have an informed conversation with your health care provider.

What Does an Abnormal Pap Result Mean?

An abnormal Pap result means that some cells collected from the cervix do not look completely typical under laboratory examination.

It does not by itself diagnose cervical cancer.

Many abnormal cervical screening results are related to HPV infection or early cell changes that can be monitored or treated before they develop into more serious disease.

Your next step depends on the specific result and other factors, including previous screening results, previous treatment for cervical cell changes, and personal health information.

That is why two people with an abnormal Pap result may receive different follow-up recommendations.

Why Can a Pap Test Be Abnormal?

There are several possible reasons cervical cells may look different from typical cells.

One important cause is infection with a high-risk type of HPV. HPV is common, and most HPV infections do not lead to cancer. However, persistent infection with certain high-risk HPV types can cause changes in cervical cells over time.

Some abnormal Pap findings can also be associated with other factors, including irritation, certain infections, hormonal changes, or other noncancerous conditions.

The Pap result alone may not explain exactly why the cells look abnormal. Your provider may use an HPV test, your previous results, or additional testing to determine the appropriate next step.

Common Abnormal Pap Results Explained

Your laboratory report may use several different terms. Here is what some of the most common ones mean.

ASC-US

ASC-US stands for atypical squamous cells of undetermined significance.

This means some squamous cells do not look completely normal, but the laboratory cannot determine from the Pap test alone why they look different.

ASC-US is the most common abnormal Pap finding. An HPV test may be used to help determine the appropriate follow-up.

An ASC-US result does not mean that you have cervical cancer.

LSIL

LSIL means low-grade squamous intraepithelial lesion.

This describes low-grade changes in cervical squamous cells. LSIL is commonly associated with HPV infection.

Low-grade changes can sometimes resolve without treatment, but your provider may recommend additional testing or monitoring depending on your overall risk and screening history.

HSIL

HSIL means high-grade squamous intraepithelial lesion.

This describes more significant abnormal changes in cervical cells.

HSIL does not mean that cancer is already present. However, high-grade changes have a greater potential to develop into cancer if they are not appropriately evaluated or treated. A provider will generally recommend further evaluation, which may include colposcopy and biopsy.

ASC-H

ASC-H means atypical squamous cells—cannot exclude HSIL.

In simple terms, some cells look abnormal and a high-grade lesion cannot be ruled out from the Pap result alone.

Because of the possibility of a higher-grade change, further evaluation such as colposcopy is commonly recommended.

AGC

AGC means atypical glandular cells.

Glandular cells are different from squamous cells and are found in areas such as the cervical canal.

An AGC result requires appropriate follow-up because it can sometimes be associated with more significant abnormalities. Your provider may recommend colposcopy and other evaluation depending on your individual circumstances.

AIS

AIS, or adenocarcinoma in situ, refers to an advanced abnormality involving glandular tissue of the cervix.

AIS is considered a precancerous lesion and requires medical evaluation and appropriate management.

What Does a Positive HPV Test Mean?

An HPV-positive result means that a high-risk type of HPV was detected.

It does not mean that you have cervical cancer.

HPV infections are common, and some infections clear on their own. The concern is persistent infection with high-risk HPV types because it can contribute to cervical cell changes over time.

The next step after a positive HPV result depends on the HPV result, Pap findings, previous screening history, and other risk factors.

For some people, the recommendation may be another screening test later. Others may need a colposcopy or additional evaluation.

Does an Abnormal Pap Mean I Have Cancer?

No.

An abnormal Pap result is not the same thing as a cancer diagnosis.

Most people with abnormal cervical screening results do not have cervical cancer. Many results represent HPV infection or cervical cell changes that can be monitored or treated before cancer develops.

This is one reason follow-up is important. Screening is designed to identify concerning changes early, when they can be evaluated appropriately.

If your report contains a term you do not understand, ask your provider to explain exactly what the result means and what follow-up is recommended.

What Happens After an Abnormal Pap?

There is no single follow-up plan for every abnormal Pap result.

Current risk-based guidance considers your present screening result together with information such as:

• Previous Pap results
• Previous HPV results
• Previous treatment for precancerous cervical changes
• Age
• Other relevant health factors

Depending on your individual risk, your provider may recommend repeating HPV or Pap testing after a specified interval, having a colposcopy and biopsy, or receiving treatment for significant cervical cell changes.

That means it is important not to compare your follow-up plan directly with someone else's.

What Is a Colposcopy?

A colposcopy is an examination that allows a health care provider to look more closely at the cervix.

During the procedure, a speculum is used to view the cervix. A special solution may be applied to help identify areas of abnormal tissue. The provider then uses a magnifying instrument called a colposcope to examine the cervix more closely.

A biopsy may be performed during the procedure if an area needs additional evaluation.

The tissue sample is examined under a microscope to determine whether abnormal cells are present and, if so, how significant the changes are.

What Does a Cervical Biopsy Show?

A biopsy can provide more information than a Pap test because it examines a small piece of cervical tissue.

Pathology results may describe cervical intraepithelial neoplasia, commonly abbreviated as CIN.

CIN is generally categorized into grades based on how abnormal the cells appear and how much of the cervical tissue is affected.

For example:

• CIN 1 represents mild changes and often resolves without treatment.
• CIN 2 represents moderate changes and may be monitored or treated depending on individual circumstances.
• CIN 3 represents severe abnormal changes and is not cancer, but it has the potential to become cancer if untreated.

Your provider should explain what your specific pathology result means and whether treatment or monitoring is recommended.

Why Your Previous Pap Results Matter

Your current result is only part of the picture.

Follow-up recommendations use a risk-based approach that can take previous screening results and previous treatment into account. This helps providers determine whether a person needs closer evaluation or can safely return for screening at a later interval.

For this reason, tell your provider about previous abnormal Pap or HPV results and any previous procedures involving abnormal cervical cells.

What If the Pap Sample Was Unsatisfactory?

Sometimes a laboratory cannot properly evaluate a Pap sample.

An unsatisfactory result may occur when there are not enough cells in the sample or when blood, mucus, or other factors make the cells difficult to evaluate.

An unsatisfactory result is different from finding abnormal cells. Your provider may recommend repeating the screening test after an appropriate interval. The National Cancer Institute notes that a repeat Pap test is commonly requested within 2 to 4 months for an unsatisfactory sample.

What Should You Do After an Abnormal Pap?

The most important step is to understand your specific result and follow the recommended follow-up plan.

Before leaving your appointment or ending a discussion with your provider, consider asking:

• What exactly does my Pap result mean?
• Was an HPV test performed?
• Was my HPV result positive or negative?
• Do I need another Pap or HPV test?
• Do I need a colposcopy?
• Will I need a biopsy?
• When should my next test or appointment happen?
• What symptoms should prompt me to contact the clinic?

Writing down the answers can make it easier to remember your care plan.

When Should You Contact Your Health Care Provider?

Contact your provider if you are unsure about your abnormal result, have not received an explanation of your follow-up plan, or are concerned about a recommended test.

Do not assume that no news means no follow-up is needed. Make sure you know whether another test, appointment, or procedure has been recommended.

If you have symptoms or concerns that are not explained by your screening result, discuss them with a health care professional rather than assuming they are caused by an abnormal Pap.
