Cervical Cancer Screening (Pap Test)

A Pap test (sometimes called a Pap smear) is a screening tool used to help find cell changes that, if left untreated, may lead to cervical cancer. Cervical cancer is cancer of the cervix, the narrow part of the uterus that opens into the vagina.

What Happens During a Pap Test

A Pap test is simple, quick, and usually only slightly uncomfortable. During the test, your doctor takes a sample of cells from your cervix.

To do this, your doctor uses an instrument called a speculum to keep the walls of the vagina apart in order to see your cervix. Your doctor then takes some cells from the cervix using a small spatula and a small brush. During the test, you may feel some light pressure or mild discomfort.

The doctor sends the cell sample to the lab, where it is examined under a microscope to see if the cells look normal.

How to Prepare for a Pap Test

Don't douche, have sex, or put anything in your vagina for at least 24 hours before the test. When you come in for the Pap test, your doctor might ask you for the date of your last period, if you are taking any hormones, or what type of birth control you use. Tell your doctor if you've had surgery on your cervix or if you've had a hysterectomy.

When to Get a Pap Test

Group Health recommends that most women between 21 and 65 years of age — who still have a uterus and have ever been sexually active, with either a man or another woman — get a Pap test on a regular schedule.

Sexual activity can expose women to many sexually transmitted infections (also called sexually transmitted diseases) including human papillomavirus (HPV). HPV can cause abnormal cell growth which, in some cases, can lead to cervical cancer.

Starting at age 21, we recommend a Pap test every three years up until age 30. Beginning at age 30, women should get a Pap test every three or five years, depending on risk. Most women will not need to continue to get Pap tests after age 65.

Even if you've had only one sexual experience, and even if it was years ago, you should have Pap tests regularly. Continue to have Pap tests until age 65, even after you're no longer sexually active.

Getting a Pap test every three or five years is safe for most women. It can take a long time for cell changes to develop into cancer. Either schedule gives your doctor a chance to find and treat changes in the cells of your cervix that could lead to cancer. Finding changes early is the key to preventing cancer.

Some women should have a Pap test more often. Ask your doctor about a schedule that's best for you if you have, or have had, any of the following:

Some women don't need Pap tests. You might not need routine Pap tests if you:

About HPV

There are two types of HPV: low-risk and high-risk. Both types of HPV can cause abnormal cell changes on the cervix. If left untreated, the changes caused by some types of high-risk HPV can develop into cervical cancer.

An HPV vaccine is available to protect against diseases caused by the specific genital human papillomaviruses (HPV) contained in the vaccine. Please talk to your doctor if you're interested.

Abnormal Pap Tests

There are many different causes for abnormal results, and only a small percentage of women with abnormal Pap test results have changes that might progress to cancer.

If changes are found, your doctor might do additional tests. These tests include testing your original Pap sample for HPV, asking you to come back for another Pap test, or having a colposcopy.

Colposcopy is an exam of the cervix. It is similar to a Pap test. An instrument called a colposcope magnifies the cervix so your doctor can take a closer look. Your doctor might remove a small tissue sample (biopsy). The tissue is examined under a microscope to look for precancerous changes.

If precancerous changes are found, there are several treatment options that can usually be done in your doctor's office.

If You Have Symptoms But It Isn't Time for a Pap Test

Some symptoms should be checked right away. If you have any of the following symptoms, or other symptoms that concern you, talk to your doctor even if it isn't time for your Pap test.
