What Should I Know About Screening?
Cervical cancer is the easiest gynecologic cancer to prevent, with regular screening tests and follow-up. Two screening tests can help prevent cervical cancer or find it early—
- The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately.
- The HPV test looks for the virus (human papillomavirushuman papillomavirus) that can cause these cell changes.
The Pap test is recommended for all women between the ages of 21 and 65 years old, and can be done in a doctor's office or clinic. During the Pap test, the doctor will use a plastic or metal instrument, called a speculum, to widen your vagina. This helps the doctor examine the vagina and the cervix, and collect a few cells and mucus from the cervix and the area around it. The cells are then placed on a slide or in a bottle of liquid and sent to a laboratory. The laboratory will check to be sure that the cells are normal.
If you get the HPV test along with the Pap test, the cells collected during the Pap test will be tested for HPV at the laboratory. Talk with your doctor, nurse, or other health care professional about whether the HPV test is right for you.
When you have a Pap test, the doctor may also perform a pelvic exam, checking your uterus, ovaries, and other organs to make sure there are no problems. There are times when your doctor may perform a pelvic exam without giving you a Pap test. Ask your doctor which tests you are having, if you are unsure.
If you have a low income or do not have health insurance, you may be able to get a free or low-cost Pap testfree or low-cost Pap test through the National Breast and Cervical Cancer Early Detection Program. Find out if you qualify.
You should start getting regular Pap tests at age 21. The Pap test, which screens for cervical cancer, is one of the most reliable and effective cancer screening tests available.
The only cancer for which the Pap test screens is cervical cancer. It does not screen for ovarian, uterine, vaginal, or vulvar cancers. So even if you have a Pap test regularly, if you notice any signs or symptoms that are unusual for you, see a doctor to find out why you're having them. If your Pap test results are normal, your doctor may tell you that you can wait three years until your next Pap test.
If you are 30 years old or older, you may choose to have an HPV test along with the Pap test. Both tests can be performed by your doctor at the same time. When both tests are performed together, it is called co-testing. If your test results are normal, your chance of getting cervical cancer in the next few years is very low. Your doctor may then tell you that you can wait as long as five years for your next screening. But you should still go to the doctor regularly for a checkup.
If you are 21–65 years old, it is important for you to continue getting a Pap test as directed by your doctor—even if you think you are too old to have a child or are not having sex anymore. If you are older than 65 and have had normal Pap test results for several years, or if you have had your cervix removed as part of a total hysterectomy for non-cancerous conditions, like fibroids, your doctor may tell you that you do not need to have a Pap test anymore.
You should not schedule your Pap test for a time when you are having your period. If you are going to have a Pap test in the next two days—
- You should not douche (rinse the vagina with water or another fluid).
- You should not use a tampon.
- You should not have sex.
- You should not use a birth control foam, cream, or jelly.
- You should not use a medicine or cream in your vagina.
It can take as long as three weeks to receive your Pap test results. If your test shows that something might not be normal, your doctor will contact you and figure out how best to follow up. There are many reasons why Pap test results might not be normal. It usually does not mean you have cancer.
If your Pap test results show cells that are not normal and may become cancer, your doctor will let you know if you need to be treated. In most cases, treatment prevents cervical cancer from developing. It is important to follow up with your doctor right away to learn more about your test results and receive any treatment that may be needed.
