What is a Pap test?
For a Pap test, your healthcare provider will collect and examine cells from your cervix. The cervix is the opening to the uterus. He or she will do this test to screen for cervical cancer and other problems.
It’s important to talk with your healthcare provider about when and how often you should have a Pap test. Experts base screening guidelines on your age and risk factors for cervical cancer.
American College of Obstetricians and Gynecologists (ACOG), guidelines include:
- If you are at least age 21, you should start cervical cancer screening, even if you are not yet sexually active.
- If you are younger than 30, you can likely be tested for cervical cancer every other year instead of yearly.
- If you are older than 30 and have had 3 normal Pap tests in a row, you can be tested once every 3 years.
- If you are at high risk for cervical cancer, you may need more screenings more often the guidelines suggest. Especially if you have a weak immune system or have been treated for abnormal cervical cells in the past.
- If you are 65 to 70 years old and have had at least 3 normal Pap tests in a row and are not sexually active, and have had no abnormal Pap tests in the past, you may decide with your healthcare provider to stop cervical cancer screening.
- If you’ve had both your uterus and cervix removed (total hysterectomy), you do not need cervical cancer screening unless you’ve had past surgery for cervical cancer or pre-cancer.
Why might I need a Pap test?
A Pap test, along with a pelvic exam, is an important part of your routine healthcare. It can help find abnormal cells that can lead to cancer. Your healthcare provider can find most cancers of the cervix early if you have regular Pap tests and pelvic exams. Cancer of the cervix is more likely to be successfully treated if it is found early.
The Pap test is useful for finding cancerous cells, and other cervical and vaginal problems such as precancerous cells and inflammation.
Your healthcare provider may use a Pap test to diagnose the following conditions:
- Abnormal cells
- Precancerous cells
Your healthcare provider may do a test for the human papilloma virus (HPV) at the same time as a Pap test. Infection with HPV is the most important risk factor for cervical cancer in women over age 30.
Your healthcare provider may have other reasons to recommend a Pap test.
What are the risks for a Pap test?
