Pap smear A Pap smear, also called a Pap test or cervical smear, tests for abnormal cells in your cervix. Pap smears can also identify vaginal infections and inflammation. They’re mainly used to screen for cervical cancer. For many decades, cervical cancer was the leading cause of cancer deaths for women in the United States. The incidence of cervical cancer has declined by 60 percent since Pap smears became available in the 1950s. When cervical cancer is found early, there’s a far greater likelihood that it can be cured. Experts have established a schedule for when and how often you should have a Pap smear. The U.S. Department of Health and Human Services, Office on Women’s Health has provided the following recommendations for women who have no known risks. What if I’ve had a hysterectomy?Ask your doctor if you need to continue having Pap smears. Usually, the tests can be stopped if your cervix was removed during your hysterectomy and you have no history of cervical cancer. To increase the accuracy of your Pap smear, there are several things you should avoid doing for 48 hours before the test. They include:
Also, you shouldn’t have a Pap smear when you’re on your period. When you have a Pap smear, you’ll be asked to lie back on the examination table with your knees up. You’ll place your feet in stirrups located on each side of the table. You’ll need to scoot your bottom to the end of the table. Your doctor will place a metal or plastic speculum in your vagina to hold it open. They’ll then use a swab to lightly scrape off some of the cells and mucus on your cervix. Most women don’t experience pain during the test, but you may feel a slight pinching or pressure. Your doctor will send your samples to a lab for evaluation under a microscope. Your doctor may also order a human papillomavirus (HPV) test. HPV tests are used for women ages 21 and older who’ve had abnormal Pap smear results and for women ages 30 and older. The Pap smear is intended as a screening test that alerts the need for further examination. It’s considered a reliable test. A 2018 study showed that routine Pap smear screening detected 92 percent of the cervical cancer cases. However, there are instances of false-negative and false-positive results, as outlined in a 2017 study. Most Pap smear test results come back as normal. This means you’ve been given an all-clear and should continue to follow the recommended schedule for future tests. You may hear these results referred to as a “negative” test. That means that you’ve tested negative for abnormalities. UnsatisfactorySometimes, Pap smear test results come back as unsatisfactory. This isn’t necessarily cause for alarm. It can mean several things, including:
If your results are unsatisfactory, your doctor may want to repeat the test right away or have you return sooner than the normally scheduled retesting. AbnormalGetting results that your Pap smear is abnormal doesn’t necessarily mean you have cervical cancer. Instead, it means that some cells were different from other cells. Abnormal results usually fall into two categories:
When changes occur in the structure of cells of your cervix, which is the lower part of the uterus that connects to your vagina, they’re considered precancerous. These precancers can usually be removed in your doctor’s office using liquid nitrogen, an electric current, or a laser beam. In a small percentage of women, these precancers will begin to grow quickly or in large numbers, and form cancerous tumors. Untreated, the cancer can spread to other parts of the body. Nearly all cervical cancer cases are caused by different types of HPV. HPV is transmitted through vaginal, oral, or anal sex. HPV infection is very common. It’s estimated that the likelihood of getting HPV at some point in life, if you have at least one sex partner, is more than 84 percent for women and 91 percent for men. You can be infected if you’ve only had one sex partner. You can have the infection for years without knowing it. Although there’s no treatment for infections with the types of HPV that cause cervical cancer, they usually go away on their own, within one or two years. We recommend that screening for cervical cancer should start at age 25 and people aged 25 to 65 should have a HPV test every 5 years. SymptomsMany women don’t have symptoms of cervical cancer, particularly pain, until it has progressed to a more advanced stage. Common symptoms include:
Certain factors put you at greater risk of getting cervical cancer. These include:
In addition to Pap smears, there are other tests that are important for women to have. Sources: Office of Women’s Health and Cleveland Clinic Health Guidelines for Women Your doctor may recommend additional tests or other timelines, depending on your medical history. Always follow your doctor’s recommendations as they are the most familiar with your health needs. Not all medicines are safe to take when you're pregnant. This includes prescribed medicines and medicines you can buy in a pharmacy or shop.
Check with a doctor, pharmacist or midwife before you take any medicines when you're pregnant. If you're already taking prescribed medicine, do not stop taking your medicine without talking to your doctor first.
It is sometimes possible to have tests to find out why you had a miscarriage and what this might mean for any future pregnancies.
Pregnant women who are due for a Cervical Screening Test should still be screened. It is safe to be screened in pregnancy, and Cervical Screening Tests have not been linked to increased rates of miscarriage. It can be a good time to have a Cervical Screening Test in the early stages of pregnancy, while you are being examined by your doctor for other matters relating to your pregnancy. It can be hard to make time for your own health after your baby is born, so it can be helpful to get the test done before the baby's arrival. If you choose to have a Cervical Screening Test after the birth of your baby, it is best to wait at least six weeks - it is ideal to wait three months. If you have a Cervical Screening Test too soon after the delivery there is an increased rate of unsatisfactory results - for instance, there may not be enough cells in the sample taken, or the cells of the cervix may still be inflamed after the pregnancy and birth.
Many people who are newly pregnant wonder if they can (or should) get a Pap smear while pregnant. The answer is yes. In fact, most doctors recommend getting a Pap smear (also known as a Pap test) in early pregnancy as a part of routine prenatal care. The test checks for abnormal cervical cells, which could mean cervical cancer. It's a good idea to get regular Pap smears even when you're not pregnant. Your doctor will likely recommend getting your first Pap test by age 21—or three years after first having sexual intercourse—and then every three years until age 29.
It's generally recommended that people with a vagina ages 30 to 65 get a Pap test—along with an HPV test—every five years. But ask your physician what the ideal frequency is for you. During a Pap smear, you undress from the waist down and lie on your back on an examining table, where you will spread your legs and put your feet into stirrups. A sheet is placed over your thighs. The doctor, midwife, or nurse practitioner uses a medical tool called a speculum, along with lubrication, to examine the cervix. They then uses a small brush or spatula to swab a sample of cells from the cervix for testing.
Some people feel nothing during a Pap smear, while others feel mild discomfort. The more that you are able to relax your body and vaginal muscles, the more comfortable the Pap test usually is. However, some people may be more sensitive to the exam than others.
Research shows that the number of cases of cervical cancer and the number of deaths from cervical cancer have decreased significantly since Pap smears became a routine test. Cervical cancer was once the leading cause of cancer deaths in women in the U.S. Research does not show a causal relationship between miscarriage and getting a pap smear while pregnant. Some people may experience light spotting after the test, due to the sensitivity of the cervix during pregnancy. However, it's extremely unlikely that a Pap test would cause a miscarriage. Usually, the fertilized egg is implanted higher up in the uterus and is not near the cervix at all. Even in the event that the fetus is implanted lower in the uterus and closer to the cervix, the cervix is quite thick in the first trimester, so the light scraping from a Pap test would not disturb an implanted fertilized egg. Unfortunately, given that roughly 15% to 20% of confirmed pregnancies end in miscarriage, some people do inevitably miscarry after having a Pap smear. Some may even start having symptoms of miscarriage after having had a Pap smear earlier that same day. However, research tells us that, by and large, these events are coincidental rather than linked. Symptoms of miscarriage might include vaginal bleeding that's bright red or brown, cramping or back pain, and the passing of tissue through the vagina. Keep in mind though that even if a miscarriage does occur, this does not mean that the Pap smear caused the pregnancy loss. It's far more likely that the miscarriage symptoms coincidentally happened to appear right after the test. If a Pap test does show abnormalities, then your doctor might perform a second test called a colposcopy, which will allow them to look at your cervix more closely. This test is still safe during pregnancy, because it only looks at the outside of the cervix.
Depending on the results of the colposcopy, your healthcare provider may recommend a follow-up Pap smear in a year. If they are concerned that the abnormal cells might become cancerous, they will surgically remove them—but not until after delivery. It's OK to wait, because cervical cancer progresses slowly. If you are worried about getting a Pap smear during early pregnancy, discuss your concerns with your prenatal care provider. It's possible that you can postpone the Pap test until your postpartum checkup, especially if you have a history of normal Pap results. However, know that the Pap test is considered safe (and is recommended) during pregnancy in order to protect your health.
