What can a pap smear tell. Pap Smear: What It Detects and Why It’s Crucial for Women’s Health
What can a Pap smear tell about your cervical health. How often should you get a Pap test. What are the limitations of Pap smears in detecting other gynecological conditions. When should you start and stop getting Pap tests.
The Science Behind Pap Smears: Unveiling Cervical Health
A Pap smear, officially known as the Papanicolaou test, is a crucial screening tool in women’s health. This procedure involves collecting cells from the cervix, which is the lower part of the uterus that connects to the vagina. The collected sample is then preserved in a special liquid and examined under a microscope for any abnormalities.
Why is this test so important? Dr. Melissa A. Simon, an obstetrician and gynecologist at Northwestern Medicine, explains: “The Pap test can detect changes in cells that could be concerning for possible cervical cancer or precancerous changes.” This early detection is vital, as cervical cancer, when caught early, has a high treatability rate.
What Can Pap Tests Detect?
Pap smears are designed to identify various cellular abnormalities that may indicate:
- Mild inflammation
- Human papillomavirus (HPV) infection
- Precancerous changes
- Cervical cancer
When abnormalities are found, they are typically classified into two categories:
- Low-grade squamous intraepithelial lesions (LSIL): These are mildly abnormal changes, often caused by HPV infection. In many cases, these changes may resolve on their own.
- High-grade squamous intraepithelial lesions (HSIL): These indicate more serious cellular changes that require further investigation and potentially treatment.
Is every abnormal result a cause for immediate concern? Not necessarily. Dr. Simon clarifies, “Cells that are determined to be atypical of undetermined significance basically reveal slightly abnormal cells, and it does not clearly mean precancer is there. Usually, these test results indicate to follow up in a year.”
The HPV Connection: Understanding the Link to Cervical Health
Human papillomavirus (HPV) is a significant factor in abnormal Pap test results. As a sexually transmitted infection, HPV can enter cells and alter their structure. While there are many strains of HPV, certain high-risk types are associated with an increased risk of various cancers, including:
- Cervical cancer
- Vulvar cancer
- Vaginal cancer
- Penile cancer
- Anal cancer
- Oral and throat cancers
How can you protect yourself against HPV? Vaccination is a powerful preventive measure. The HPV vaccine targets the most common types of HPV associated with cancer and genital warts. By getting vaccinated, you can significantly reduce your risk of HPV-related health issues.
Beyond the Pap: Additional Diagnostic Procedures
Depending on your Pap test results, your healthcare provider may recommend further testing. What are these additional procedures?
Colposcopy: A Closer Look
A colposcopy involves using a special camera to examine the cervix in detail. During this procedure, your doctor may take a small tissue sample (biopsy) for further analysis. This helps to determine the extent and severity of any cellular changes.
LEEP: Removing Abnormal Tissue
In cases of more concerning findings or repeated abnormal Pap results, a Loop Electrosurgical Excision Procedure (LEEP) may be recommended. This procedure removes a small portion of cervical tissue for both diagnostic and treatment purposes.
The Limitations of Pap Smears: What They Can’t Tell Us
While Pap tests are invaluable for detecting cervical abnormalities, they have limitations. What can’t a Pap smear detect?
Ovarian Cancer: Beyond the Reach of Pap Tests
Due to the location of the ovaries, Pap smears are not effective in detecting ovarian cancer. For ovarian cancer cells to be detected in a Pap test, they would need to travel through the fallopian tubes, uterus, and reach the cervix – an extremely unlikely scenario.
Other STIs: The Need for Specific Testing
Pap tests are not designed to detect other sexually transmitted infections (STIs). If you’re concerned about STIs, it’s important to request specific screening tests from your healthcare provider.
Pap Test Guidelines: When to Start and How Often to Screen
When should you start getting Pap tests, and how frequently should you have them? The recommendations can vary slightly depending on the organization:
- The U.S. Preventive Services Task Force (USPSTF) and the American College of Obstetricians and Gynecologists (ACOG) recommend starting screening at age 21.
- The American Cancer Society suggests beginning cervical cancer screening at age 25.
How often should you get screened? The general guidelines are:
- Pap test every three years
- Primary HPV testing every five years
- Co-testing (combined HPV and Pap test) every five years if primary HPV testing is not available
Dr. Simon emphasizes the importance of individualized care: “There are many nuances and complexities of when to start screening and how frequently screening should be done.” She recommends discussing your personal risk factors and screening needs with your healthcare provider.
When to Seek Medical Attention: Beyond Routine Screening
While regular Pap tests are crucial, there are times when you should seek medical attention outside of your scheduled screenings. Dr. Simon advises, “If you have vaginal discharge, abnormal bleeding or are feeling pain, schedule a visit with your healthcare clinician to discuss these symptoms.”
She further emphasizes, “It’s important that if you are ever in any doubt of what you are feeling or experiencing, and are questioning if you need screening or a test, always reach out to your care team so you can have that conversation.”
Pap Tests in Older Adults: When to Stop Screening
Is there an age when Pap tests are no longer necessary? The USPSTF, ACOG, and American Cancer Society agree that people over 65 may not need continued screening under certain conditions. These include:
- Adequate prior screening with normal results
- No history of cervical cancer
- No high risk factors for cervical cancer
However, Dr. Simon stresses the importance of personalized care: “Talk to your primary care clinician about your individual risks and recommendations for screening.”
The Evolution of Cervical Cancer Screening: Beyond the Pap
While Pap tests have been the gold standard for cervical cancer screening for decades, the field is evolving. What new developments are shaping the future of cervical cancer detection?
HPV Testing: A Primary Screening Tool
In recent years, HPV testing has emerged as a valuable screening method, either alone or in combination with Pap tests. Primary HPV testing can detect the presence of high-risk HPV types before cellular changes are visible, potentially allowing for earlier intervention.
Self-Sampling: Increasing Access to Screening
Self-sampling for HPV is gaining traction as a way to increase screening rates, especially in underserved populations. This method allows women to collect their own samples at home, which are then sent to a lab for analysis. While not yet widely implemented, self-sampling could revolutionize cervical cancer screening by improving accessibility and reducing barriers to care.
The Role of Lifestyle in Cervical Health
While regular screening is crucial, lifestyle factors also play a significant role in cervical health. How can you reduce your risk of cervical cancer beyond getting regular Pap tests?
Smoking Cessation: A Key Prevention Strategy
Smoking has been linked to an increased risk of cervical cancer. Quitting smoking not only reduces this risk but also improves overall health. If you’re a smoker, talk to your healthcare provider about smoking cessation programs and resources.
Safe Sex Practices: Reducing HPV Transmission
Since HPV is sexually transmitted, practicing safe sex can help reduce your risk of infection. This includes using condoms consistently and limiting the number of sexual partners.
Nutrition and Exercise: Supporting Overall Health
A healthy diet rich in fruits and vegetables, along with regular exercise, can boost your immune system. While not directly preventing cervical cancer, a strong immune system is better equipped to fight off HPV infections and other potential threats to cervical health.
Pap Tests and Pregnancy: What Expectant Mothers Should Know
Pregnancy brings many changes to a woman’s body, but what about cervical cancer screening? Is it safe to have a Pap test while pregnant?
Safety of Pap Tests During Pregnancy
In general, Pap tests are safe to perform during pregnancy. However, the timing is important. Ideally, a Pap test should be done as part of preconception care or during the first prenatal visit. If a woman is due for a Pap test during pregnancy, it’s typically safe to perform in the first or second trimester.
Handling Abnormal Results
If a Pap test during pregnancy shows abnormal results, what happens next? In most cases, further evaluation can safely wait until after delivery. However, in some situations, a colposcopy might be recommended during pregnancy. Your healthcare provider will weigh the risks and benefits to determine the best course of action.
The Psychological Impact of Pap Tests: Addressing Anxiety and Fears
While Pap tests are crucial for health, they can also cause anxiety for many women. How can healthcare providers and patients address these concerns?
Communication is Key
Open communication between patients and healthcare providers is crucial. Discussing the procedure, its importance, and what to expect can help alleviate fears. Providers should encourage questions and provide clear, compassionate answers.
Coping with Abnormal Results
Receiving abnormal Pap test results can be frightening. It’s important to remember that abnormal results are common and often do not indicate cancer. Healthcare providers should explain results clearly and outline next steps to help reduce anxiety.
Support Resources
Many organizations offer support and information for women dealing with abnormal Pap results or cervical health issues. These resources can provide valuable education and emotional support.
The Global Perspective: Cervical Cancer as a Public Health Issue
Cervical cancer is a significant global health concern, particularly in low- and middle-income countries. How does cervical cancer screening vary around the world?
Disparities in Access to Screening
While Pap tests are routine in many developed countries, access to regular screening is limited in many parts of the world. This contributes to higher rates of cervical cancer in these regions.
Alternative Screening Methods
In areas where traditional Pap tests are not feasible, alternative screening methods are being implemented. These include visual inspection with acetic acid (VIA) and HPV DNA testing, which can be more accessible and cost-effective in resource-limited settings.
Global Initiatives
The World Health Organization has set a goal to eliminate cervical cancer as a public health problem globally. This ambitious target involves increasing HPV vaccination rates, improving screening coverage, and ensuring access to treatment for precancerous lesions and cervical cancer.
The Future of Cervical Cancer Prevention: Emerging Technologies and Approaches
As medical science advances, new technologies and approaches are emerging in the field of cervical cancer prevention. What innovations might shape the future of cervical health?
Artificial Intelligence in Screening
Artificial intelligence (AI) is being explored as a tool to improve the accuracy and efficiency of cervical cancer screening. AI algorithms can analyze Pap test images and HPV test results, potentially detecting abnormalities that human eyes might miss.
Therapeutic Vaccines
While the HPV vaccine is preventive, researchers are working on therapeutic vaccines that could treat existing HPV infections or precancerous lesions. These vaccines aim to stimulate the immune system to clear the virus and reverse cellular changes.
Personalized Screening Approaches
As our understanding of individual risk factors improves, screening protocols may become more personalized. This could involve tailoring the frequency and type of screening based on factors such as HPV status, genetic markers, and lifestyle factors.
Empowering Women: The Role of Education in Cervical Health
Knowledge is power when it comes to health. How can we better educate women about cervical health and the importance of screening?
Starting Early: Health Education in Schools
Incorporating comprehensive sexual health education in schools can lay the foundation for lifelong cervical health awareness. This should include information about HPV, the importance of vaccination, and the role of regular screening.
Leveraging Technology for Health Education
Mobile apps, social media campaigns, and online resources can reach women where they are, providing accessible, accurate information about cervical health. These platforms can also send reminders for screenings and vaccinations.
Community Outreach Programs
Community-based education programs, particularly those targeting underserved populations, can help bridge knowledge gaps and increase screening rates. These programs can address cultural barriers and provide information in multiple languages.
By empowering women with knowledge about cervical health and the importance of regular screening, we can work towards reducing the burden of cervical cancer worldwide. Remember, early detection through regular Pap tests and HPV screening, combined with appropriate follow-up care, remains our best defense against cervical cancer.
What Does a Pap Test Detect?
Updated November 2022
Its real name: Papanicolaou test. There’s a good chance you know it as a Pap smear, or more appropriately, a Pap test. Discover the science behind this test — including what it doesn’t detect.
The Science Behind the Test
A Pap test is when a clinician takes a sample of cells from your cervix (the lower part of the uterus neck located at the top of the vagina). Then, they put the cells into small jar with a special liquid to preserve the sample so it can be tested for abnormalities under a microscope.
There are many reasons why you may have abnormal findings, such as:
- Mild inflammation
- Human papillomavirus (HPV)
- Cancer or precancer
Cervical cancer, if caught early, is highly treatable.
— Melissa A. Simon, MD
“The Pap test can detect changes in cells that could be concerning for possible cervical cancer or precancerous changes,” says Melissa A. Simon, MD, an obstetrician and gynecologist at Northwestern Medicine.
Abnormal test results will indicate a number of atypical squamous cells, which will then be classified as low-grade or high-grade squamous intraepithelial lesions (LSIL and HSIL, respectively). LSIL indicates that the changes are mildly abnormal and usually caused by HPV infection, and they may go away on their own. HSIL suggests more serious changes.
“Cells that are determined to be atypical of undetermined significance basically reveal slightly abnormal cells, and it does not clearly mean precancer is there. Usually, these test results indicate to follow up in a year,” says Dr. Simon.
Abnormal Pap test results are typically caused by HPV. HPV is a sexually transmitted infection (STI) that enters cells and changes them. HPV can be prevented by getting the vaccine, which targets the HPV types that most commonly cause certain types of cancer and genital warts. Certain high-risk types of HPV are associated with an increased risk for the following types of cancer:
- Cervical
- Vulva
- Vagina
- Penis
- Anus
- Mouth and throat cancer
Depending on your Pap test results, your physician will determine the appropriate next steps. This can include another test, known as a colposcopy, which uses a special camera to look at your cervix. During this procedure, a biopsy of cells on your cervix may be taken for further analysis. Your physician may also opt for a loop electrosurgical excision procedure, known as LEEP, if there are more concerning findings or repeated abnormal Pap test results. A LEEP removes part of your cervix tissue for diagnosis and/or treatment.
What It Can’t Determine
Although Pap tests can help detect precancerous cells on the cervix, there are other types of gynecologic cancers that Pap tests cannot detect.
Because your ovaries are far away from your cervix, it is extremely unlikely that a Pap test will detect ovarian cancer. For that to happen, the cancer cells would have to travel away from your ovaries, through your fallopian tubes and uterus, and into the area surrounding your cervix.
The Pap test is also limited in detecting other types of STIs. If you are concerned you may have a STI, you should ask your clinician to screen for specific STIs.
Pap Tests Are Part of Routine Screening
The U.S. Preventive Services Task Force (USPSTF) and the American College of Obstetricians and Gynecologists (ACOG) both suggest starting screening at age 21. However, the American Cancer Society suggests that cervical cancer screening begin at age 25.
Dr. Simon explains that there are many nuances and complexities of when to start screening and how frequently screening should be done. Cervical cancer can also take a long time to develop, which could explain the varying guidelines.
Screening with a Pap test every three years during this time period is acceptable. However, other types of screening include primary HPV testing every five years. If primary HPV testing is not available, screening may be performed with co-testing that combines an HPV test with a Pap test every five years.
“If you have vaginal discharge, abnormal bleeding or are feeling pain, schedule a visit with your healthcare clinician to discuss these symptoms,” says Dr. Simon. “It’s important that if you are ever in any doubt of what you are feeling or experiencing, and are questioning if you need screening or a test, always reach out to your care team so you can have that conversation.”
The USPSTF, ACOG and American Cancer Society agree that people older than 65 do not need to be screened if adequate prior screening has been completed with normal results and if there is no history or high risk of cervical cancer. Dr. Simon recommends talking to your primary care clinician about your individual risks and recommendations for screening.
Bottom Line
The Pap test is a screening tool that can help detect abnormal cells on your cervix. This early detection can be important in stopping precancerous cells from progressing to cervical cancer.
“Cervical cancer, if caught early, is highly treatable. And that’s why engaging in routine screening is very important,” says Dr. Simon. “Between the HPV vaccine and routine testing, this type of cancer really should be nonexistent. ”
What Should I Know About Cervical Cancer Screening?
Español (Spanish) | Print
“If I didn’t go to that appointment, I might not be around for my kids,” says Cindy. Her cervical cancer screening test found precancerous cells. She shares her story in this video.
The HPV test and the Pap test can help prevent cervical cancer or find it early.
- The HPV test looks for the virus (human papillomavirus) that can cause cell changes on the cervix.
- 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.
Both tests 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 look inside 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 sent to a laboratory.
- If you are getting a Pap test, the cells will be checked to see if they look normal.
- If you are getting an HPV test, the cells will be tested for HPV.
What is cervical precancer? When there are cervical cells that look abnormal but are not yet cancerous, it is called cervical precancer. These abnormal cells may be the first sign of cancer that develops years later. Cervical precancer usually doesn’t cause pain or other symptoms. It is found with a pelvic exam or a Pap test.
If you have a low income or do not have health insurance, you may be able to get a free or low-cost screening test through the National Breast and Cervical Cancer Early Detection Program.

When to Get Screened
If You Are 21 to 29 Years Old
You should start getting Pap tests at age 21. If your Pap test result is normal, your doctor may tell you that you can wait three years until your next Pap test.
If You Are 30 to 65 Years Old
Talk to your doctor about which testing option is right for you—
- An HPV test only. This is called primary HPV testing. If your result is normal, your doctor may tell you that you can wait five years until your next screening test.
- An HPV test along with the Pap test. This is called co-testing. If both of your results are normal, your doctor may tell you that you can wait five years until your next screening test.
- A Pap test only. If your result is normal, your doctor may tell you that you can wait three years until your next Pap test.
If You Are Older Than 65
Your doctor may tell you that you don’t need to be screened anymore if—
- You have had normal screening test results for several years, and
- You have not had a cervical precancer in the past, or
- You have had your cervix removed as part of a total hysterectomy for non-cancerous conditions, like fibroids.
No special preparation is needed before you have an HPV test.
If you are getting a Pap test, you can take steps to make sure the test results are accurate. Avoid intercourse, douching, and using vaginal medicines or spermicidal foam for 2 days before the test. If you had sex before the test, go to the appointment as planned and let the doctor know.
If you have your period, don’t worry. Both tests can still be done at this time.
Test Results
It can take as long as three weeks to receive your 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 test results might not be normal. It usually does not mean you have cancer.
If your 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.
If your test results are normal, your chance of getting cervical cancer in the next few years is very low. Your doctor may tell you that you can wait several years for your next cervical cancer screening test. But you should still go to the doctor regularly for a checkup.

I express my deep gratitude to Ekaterina Borisovna for her competent and professional approach to work, interested and sensitive attitude towards patients. I came to Ekaterina Borisovna on the recommendation, in a difficult situation – anemia of moderate severity, my hemoglobin was 70!! Ekaterina Borisovna was attentive to my problem, asked in detail about the prescription and symptoms of the disease, and prescribed an effective and prompt treatment – after 3 weeks, hemoglobin was already 120! My whole body condition improved – dry skin disappeared, hair stopped falling out, brittle nails decreased, a blush played on my cheeks !! But that’s not all, Ekaterina Borisovna was also able to correctly determine the cause of the disease, and recommended options for its treatment. I have had multiple uterine fibroids for more than 10 years, which affects the cycle and causes heavy periods, and all gynecologists unanimously stated that in my situation the uterus needs to be removed – pre-menopausal age, complex nodes, etc. And here I want to note that Ekaterina Borisovna, with high professionalism, has a great desire to understand the patient’s problem and provide him with real help. Thanks to her caring attitude towards me, her advice and recommendations, I managed to avoid the removal of the uterus and implement a more gentle treatment option for uterine fibroids. Thank you so much, Ekaterina Borisovna, you are a doctor with a capital letter, as well as just a wonderful person and a charming woman!! Thanks for your hard work!!

Ekaterina Borisova is an incredible specialist and a great person. For three years I suffered from various diseases of the gastrointestinal tract (erosion, inflammation, irritable bowel syndrome, etc.), and, frankly, I already gave up on myself. Couldn’t eat, couldn’t sleep, and other moments. Not a single doctor understood what was happening to me, why I felt so bad and where the legs of my problems grow from. But I was lucky, I went to the right doctor. First, they listened to me carefully (and this is generally a rarity, to be honest), then they conducted many tests and diagnostics (absolutely justified, and not for show), and every source of my ailments was found and eliminated. It took me about 5 months to feel better, and that’s more to blame for the pandemic and personal moments because of which I interrupted the treatment. I want to note that Ekaterina Borisovna even suggests which manufacturer (country) to buy medicines from, so that they work better. He also remembers your diagnosis and name, which is also nice. Thank you, my deepest respect and sincere appreciation for your competence, ability to cheer and personal interest in the result.

What do the smears mean? Encyclopedia of the IVF Clinic
Any visit by a woman to a gynecologist is always accompanied by taking swabs. What do they mean? The doctor obstetrician-gynecologist of the Department of Obstetrics and Gynecology of the Medical Academy of Postgraduate Education of St. Petersburg Marina Vladislavovna BONDARENKO tells.
Any visit by a woman to a gynecologist is always accompanied by a swab. What do they mean? The doctor obstetrician-gynecologist of the Department of Obstetrics and Gynecology of the Medical Academy of Postgraduate Education of St. Petersburg Marina Vladislavovna Bondarenko tells.
Flora smear
Flora smear is the most common test in gynecological practice. It is taken both at the first visit to the doctor and at subsequent visits. If a woman is healthy, then such a prophylactic smear is done with a frequency of about once every 3 months. In cases where it is necessary to confirm a particular disease or test the effectiveness of treatment, it makes sense to examine it at every visit to the doctor.
Before the procedure, you should not go to the toilet “in a small way” for 2-3 hours. Otherwise, you may wash away bacteria and epithelium, which are important for a correct diagnosis. For a day, you must refrain from intimate contacts. Also, do not use spermicidal creams or douche.
A prophylactic flora swab is taken from a healthy woman approximately once every three months. When performed correctly, a smear on the flora can say a lot. First of all, determine the number of leukocytes. If there are a lot of white blood cells, then you may have inflammation. The type of microflora is also determined in this smear. It is directly related to the phase of the menstrual cycle. In the analysis, there may be different cells of the rod or cocci. If there is inflammation, then there will always be a lot of cells, since they are rejected faster. “Cluster cells” characteristic of sexually transmitted diseases (STDs) may appear. This also suggests that it is time to take care of your health. When gonococci or Trichomonas appear in the analyzes, then you definitely should not put off a visit to the doctor. Although it should be noted that only those gonococci that “sit” inside the cell are dangerous. But extracellular ones can be present in a smear in an absolutely healthy woman.
You also need to remember that the diagnosis of gonorrhea can only be made after inoculation on special media. So I’ll have to take another smear. Before this, treatment cannot be started.
If filaments of mycelium are found in your flora smear, then this is a characteristic sign of candidiasis, in other words, “thrush”. However, for the final statement of that diagnosis, it is also not possible to do without sowing.
“Sterility” swab
At the gynecologist’s appointment, you can take a swab to check the degree of purity and hormonal levels. It determines the composition of the contents of the vagina, which is normally represented by a secret, various epithelial cells and coccal microflora. In order to properly conduct the study, you need to use a sterile Tampax-type swab, which is removed after 8 hours. It is most convenient to introduce it at night and remove it in the morning at a gynecologist’s appointment. The swab is sent to the laboratory in a sterile tube.
The degree of purity as a result of a smear is expressed in numbers:
1 and 2 are indicators of health, and 3 and 4 indicate the presence of colpitis – inflammation of the vagina.
There is also a smear for hormonal levels. It shows how during the menstrual cycle the female body is affected by sex hormones – estrogens and progesterone. According to its results, it is possible to establish how correctly and in what quantity they are produced.
A variant of this smear is the Threat swab. It is used during pregnancy to determine the risk of termination.
Pap smear or Pap test
Papanicolaou test or Pap test is needed to detect abnormalities in the cells of the cervix. In our country, it is also called a smear for atypical cells or cytology. All these are “names” of one analysis.
A Pap smear should not be done during menstruation or if there is inflammation, as the result may be false. During the day, as well as when taking a smear for flora, you should avoid intimacy, do not use candles or tampons.
In a cytological smear, the size, shape, number and location of cells are evaluated. In young girls, according to this analysis, it is possible to assess the correct production of estrogens. A smear is considered normal or negative when all cells are of normal size and shape and there are no abnormal cells. Atypical cells are “wrong” cells. They have the wrong shape, size, and they are often not located as they should.
In the first half of the cycle, the cells are located separately, in the second half, the cells seem to “bunch”. Therefore, such a smear is sometimes called “dirty”. To describe an abnormal smear, cytologists use special terms: dysplasia of 1, 2, 3 degrees, atypia. With grade 1 dysplasia, it is necessary to repeat the study after 3-6 months. Such a result can be with untreated chlamydia, gonorrhea or trichomoniasis. Therefore, it is necessary to repeat the procedure after a course of treatment.
In the case when dysplasia was found in the previous smear, or the woman or her partner suffered from herpes or genital warts, an additional examination should be done – colposcopy.
If grade 2 or 3 dysplasia is detected, then a biopsy is indispensable in this case. At the same time, a small piece of tissue is taken from the changed area. If atypical cells are detected, consultation with an oncologist is necessary.
An abnormal smear does not always mean that a woman has cervical cancer. In inflammation, cells can also look abnormal. But after treatment, the smear usually becomes normal.
According to the latest recommendations of the American Cancer Society, which Russian gynecologists also adhere to, a Pap test should be performed for all women from 20 years old once a year. If the result is negative twice, then the analysis can be repeated at least once every 3 years, up to 65 years. Women with a large number of sexual partners, infertility, menstrual irregularities, and genital herpes need more frequent examinations. As well as ladies taking hormonal contraceptives and obese.
