What is a Pap test?
Why do I need a Pap test?The Pap test, also called a Pap smear, checks for changes in the cells of your cervix. The cervix is the lower part of the uterus (womb) that opens into the vagina (birth canal). The Pap test can tell if you have an infection, abnormal (unhealthy) cervical cells, or cervical cancer.
A Pap test can save your life. It can find the earliest signs of cervical cancer. If caught early, the chance of curing cervical cancer is very high. Pap tests also can find infections and abnormal cervical cells that can turn into cancer cells. Treatment can prevent most cases of cervical cancer from developing.
Getting regular Pap tests is the best thing you can do to prevent cervical cancer. In fact, regular Pap tests have led to a major decline in the number of cervical cancer cases and deaths.
Do all women need Pap tests?
It is important for all women to have Pap tests, along with pelvic exams, as part of their routine health care. You need a Pap test if you are 21 years or older.
Women who have gone through menopause (when a woman's periods stop) still need regular Pap tests. Women ages 65 and older can talk to their doctor about stopping after at least 3 normal Pap tests and no abnormal results in the last 10 years.
How often do I need to get a Pap test?
It depends on your age and health history. Talk with your doctor about what is best for you. Most women can follow these guidelines:
- Starting at age 21, have a Pap test every 2 years.
- If you are 30 years old and older and have had 3 normal Pap tests for 3 years in a row, talk to your doctor about spacing out Pap tests to every 3 years.
- If you are over 65 years old, ask your doctor if you can stop having Pap tests.
Ask your doctor about more frequent testing if:
- You have a weakened immune system because of organ transplant, chemotherapy, or steroid use
- Your mother was exposed to diethylstilbestrol (DES) while pregnant
- You are HIV-positive
Women who are living with HIV, the virus that causes AIDS, are at a higher risk of cervical cancer and other cervical diseases. The U.S. Centers for Disease Control and Prevention recommends that all HIV-positive women get an initial Pap test, and get re-tested 6 months later. If both Pap tests are normal, then these women can get yearly Pap tests in the future.
The only women who do not need regular Pap tests
are:
- Women over age 65 who have had 3 normal Pap tests and in a row and no abnormal test results in the last 10 years,and have been told by their doctors that they don't need to be tested anymore.
- Women who do not have a cervix and are at low risk for cervical cancer. These women should speak to their doctor before stopping regular Pap tests.
I had a hysterectomy. Do I still need Pap tests?
It depends on the type of hysterectomy (surgery to remove the uterus) you had and your health history. Women who have had a hysterectomy should talk with their doctor about whether they need routine Pap tests.
Usually during a hysterectomy, the cervix is removed with the uterus. This is called a total hysterectomy. Women who have had a total hysterectomy for reasons other than cancer may not need regular Pap tests. Women who have had a total hysterectomy because of abnormal cells or cancer should be tested yearly for vaginal cancer until they have three normal test results. Women who have had only their uterus removed but still have a cervix need regular Pap tests. Even women who have had hysterectomies should see their doctors yearly for pelvic exams.
How can I reduce my chances of getting cervical cancer?
Aside from getting Pap tests, the best way to avoid cervical cancer is by steering clear of the human papillomavirus (HPV). HPV is a major cause of cervical cancer. HPV infection is also one of the most common sexually transmitted infections (STI). So, a woman boosts her chances of getting cervical cancer if she:
- Starts having sex before age 18
- Has many sex partners
- Has sex partners who have other sex partners
- Has or has had a STI
