A Pap smear is a test used to detect any abnormalities in cells on the cervix. Abnormalities may indicate the presence of a disease, such as cervical cancer, or other complications, such as the human papillomavirus (HPV).
Common abnormalities that can be detected in a Pap smear include:
-Cellular changes that indicate the presence of an infection. Inflammation, atypia (abnormal cell shapes), and material that suggest infection or infection-related diseases can be detected.
-Abnormal cells or tissue in the cervix. Abnormal cells that are pre-cancerous or malignant can be detected through the Pap test. These cells may indicate cervical cancer, dysplasia, precancerous cervical lesions, or malignant cervical lesions.
-HPV. HPV is a virus that can cause genital warts, lesions, and even cancer. HPV can be detected through a Pap smear.
-Abnormal endometrial cells. Endometrial cells that are abnormal may indicate endometrial cancer, endometritic granulomas, endometritis, or endometrial hyperplasia.
By identifying any abnormalities in the Pap smear, doctors can recommend further tests or treatments. It is important to receive regular Pap smears to ensure that any abnormalities are detected early and can be treated quickly and effectively.

What are the five categories of Pap smear abnormalities?
The five categories of Pap smear abnormalities are:
1. Atypical squamous cells (ASC): Abnormal cells, usually caused by HPV, that are not typically cancerous.
2. Atypical glandular cells (AGC): Abnormal cells, usually caused by HPV, that may develop into cancerous cells.
3. Dysplasia: Abnormal changes in the size and shape of cells that can be precancerous, meaning they can develop into cancerous cells.
4. Squamous intraepithelial lesions (SIL): Abnormal changes in the number of squamous cells found in the cervix that can be precancerous.
5. Endocervical cell changes: Abnormal changes in the number of endocervical cells that can be precancerous.
What is the most common abnormal Pap result?
The most common abnormal Pap result is an ASC-US (Atypical Squamous Cells of Undetermined Significance). This is an equivocal (uncertain) finding that often needs to be followed up with further testing (such as a repeat Pap, an HPV test, or a colposcopy).
An abnormal Pap result can also indicate an infection or inflammation. In these cases, a Pap test may reveal abnormal cells due to inflammation caused by a bacterial, viral, or fungal infection. HPV (Human Papillomavirus), which is the most common sexually transmitted infection, can also cause changes to Pap results.
This includes low grade abnormalities such as ASC-US, as well as more significant changes such as ASC-H (Atypical Squamous Cells – cannot exclude HSIL), LSIL (Low Grade Squamous Intraepithelial Lesion), or HSIL (High Grade Squamous Intraepithelial Lesion).
In all of these circumstances, further testing is needed to determine the precise cause of the abnormal Pap result.
What is a Class 5 finding in a Pap smear?
A Class 5 finding in a Pap smear is an abnormal cervical cell abnormality. It is a serious precancerous abnormality and is considered higher risk than a Class 2, 3, or 4 abnormality. Class 5 typically requires more intense follow-up and monitoring.
Common Class 5 findings can include changes in size, shape, and number of cervical cells. These findings can also include the presence of abnormal cells such as epithelial cell changes, columnar cell changes, musty cells, and abnormal glandular cell changes.
The presence of Class 5 findings in a Pap smear indicates that further evaluation is needed to determine whether these abnormal cells are related to a pre-existing or underlying condition. In some cases, further evaluation and testing may be recommended, including biopsies or further imaging tests.
It is important to discuss the potential significance of a Class 5 finding with a healthcare provider to determine the best treatment course.
What are the different types of abnormal cells in cervix?
These include squamous intraepithelial lesions (SIL), dysplastic cells, human papillomavirus (HPV) cells, and metaplastic cells.
Squamous intraepithelial lesions (SIL) are caused by the presence of precancerous or cancerous cells in the layers of the cervix. This is the most common type of abnormal cells found in the cervix, and they can range from low-grade to high-grade lesions.
Low-grade lesions are usually benign, while high-grade lesions are more likely to develop into cervical cancer.
Dysplastic cells are the second most common type of abnormal cell present in the cervix. These cells are usually caused by HPV, which can lead to cervical cancer if left untreated. Dysplastic cells are usually detected through a Pap smear, as they can vary in size and shape from other normal cells.
Human papillomavirus (HPV) cells are also present in the cervix, and they can lead to the development of cervical cancer if left untreated. HPV is a sexually-transmitted infection, and it is the leading cause of cervical cancer in the United States.
Metaplastic cells are abnormal cells that occur when normal cells are replaced with abnormal ones. These abnormal cells are usually caused by environmental factors, such as smoking and long-term use of certain medications.
Metaplastic cells can also occur in other parts of the body, such as the uterus and the bladder.
In conclusion, there are several different types of abnormal cells that can be present in the cervix. The most common are squamous intraepithelial lesions (SIL), dysplastic cells, human papillomavirus (HPV) cells, and metaplastic cells.
All of these abnormal cells can lead to cervical cancer if left untreated, so it is important to get regular Pap smears to detect any possible symptoms.
How worried should I be about an abnormal Pap smear?
You should definitely be concerned about an abnormal Pap smear and it’s important to follow up with your doctor for further testing. An abnormal Pap smear can be an indicator of abnormal cell growth in the cervix and it could be a sign of a precancerous or cancerous condition.
While abnormal cells can sometimes be caused by infections, it’s important to identify any potential issues early. Your doctor may recommend further testing such as a colposcopy, biopsy, HPV testing, or other tests.
It’s important to follow up on any recommendations your doctor makes so that you can be sure you are as healthy as possible.
What is the next step after an abnormal Pap smear?
After an abnormal Pap smear, a follow-up appointment is normally scheduled to discuss the results. During this appointment, the healthcare provider will determine the best treatment plan based on the individual’s age and the findings on the Pap smear.
Options could range from a follow-up Pap test, a colposcopy to take a closer look at the cervix, or a biopsy to collect tissue samples. If a biopsy is suggested, the healthcare provider will discuss the procedure in detail, explain any possible risks, and answer any questions from the patient.
Depending on the results of the follow-up or any treatment, the patient may need to make additional appointments with the healthcare provider to monitor for any changes or for follow-up tests.
How often are abnormal Pap smears wrong?
Abnormal Pap smear results can sometimes be wrong due to a variety of factors, such as specimen collection errors, laboratory errors, or an incorrect interpretation of the results. Nevertheless, the accuracy of Pap smear screening tests is generally quite high, with estimates ranging from 80-95% depending on the study.
It is also important to note that in some cases, a Pap test may yield an unclear result but not be definitively wrong, as the abnormalities may still require further testing and evaluation. Such ambiguous Pap results may include mildly atypical squamous cells of undetermined significance (ASCUS) and atypical glandular cells (AGS).
In such cases, an additional test or follow-up may be necessary to determine a definitive diagnosis.
Overall, although Pap smear results can, on rare occasions, be wrong due to chance or human error, the accuracy rate is usually quite high. For best results, it is recommended that patients follow their doctor’s recommended guidelines for tests and screenings.
How long does it take to remove abnormal cells from cervix?
The length of time it takes to remove abnormal cells from the cervix can vary depending on a number of factors. Generally, during a procedure known as a “loop electrosurgical excision procedure” or “LEEP”, abnormal cells are scraped away from the cervix with a thin wire loop.
This procedure generally takes between 15-30 minutes. However, depending on the complexity of the procedure and specific individual factors, the amount of time needed to remove the abnormal cells can be longer.
Additionally, if an individual needs an anesthetic, additional preparation and recovery time may also be needed. Additional follow-up procedures and/or biopsies may also be required following the initial procedure.
What happens if your smear comes back abnormal?
If a Pap test (or “smear”) comes back abnormal, it means that the cells taken from the cervix show changes that are not normal. An abnormal result does not mean that you have cervical cancer or any other health problem, but it may indicate an increased risk.
If a Pap test is abnormal, the doctor may suggest further tests such as a colposcopy, a special examination of the vagina and cervix with a microscope. A colposcopy can help a doctor determine if there is a need for a biopsy – a procedure which takes a small sample of cervical tissue for laboratory analysis.
Depending on the result of the colposcopy, additional biopsies, HPV testing, and possibly other treatments may be recommended. Following an abnormal result, your doctor can recommend screening and monitoring options to ensure your health and safety.
Can HPV go away after abnormal Pap?
Yes, Human Papillomavirus (HPV) can go away after an abnormal Pap test result. HPV is a very common virus and in most cases, the body’s immune system will clear HPV infection on its own and the Pap test will eventually become normal.
However, in some cases it may take months or even years for the body to clear HPV entirely and the Pap test can remain abnormal. If HPV persists, it can lead to possible pre-cancerous or cancerous changes in cervical cells.
That is why it is important to follow-up with your doctor regularly to monitor changes in your cervical cells. Depending on the results, your doctor may recommend further testing and/or treatments.
Should I be worried if I need a colposcopy?
Having a colposcopy is a common and necessary procedure for many people, so there is no need to be worried about it. A colposcopy is an outpatient procedure used to closely examine the cervix, vagina, and vulva for abnormalities.
It is usually recommended if an abnormal Pap test result was found or if an infection was detected during a regular pelvic exam.
During a colposcopy, a healthcare provider uses a device called a colposcope—which is like a magnifying glass—to look closely at the tissues of the cervix and vagina. A biopsy of the tissues may be taken as part of the procedure.
This may cause some discomfort, but it is important to remember that it is a common procedure and is necessary to prevent further issues.
Your healthcare provider will advise you on how to prepare for the procedure. It is likely that they will ask you to avoid sex and using douches, tampons or other vaginal cleaners for a few days ahead of the colposcopy.
It is important to remember that a colposcopy is a routine procedure and doesn’t necessarily mean that you have a serious medical problem. So, while it is normal to be a bit anxious, overall there is no need to be worried about the prospect of needing a colposcopy.
What causes an abnormal Pap smear other than HPV?
An abnormal Pap smear can be caused by a variety of factors other than Human Papillomavirus (HPV). These can include infections such as Vaginal Trichomoniasis, Candidiasis (Yeast infection), Chlamydia and Gardnerella.
Other causes could be inflammation due to medical conditions such as Atrophic Vaginitis (inflammation of the vagina due to thinning of the vaginal wall) or Cervicitis (inflammation of the uterus or cervix).
Another cause could be the presence of polyps in the reproductive organs, which can be caused by hormonal imbalances. Certain drugs, specifically antibiotics, can also cause an abnormal Pap smear, as they can alter the normal microflora in the vagina.
Additionally, recent findings now suggest that women who use hormonal birth control and intrauterine devices (IUDs) may have an increased likelihood of an abnormal Pap smear result, since these can alter the hormones and cause inflammation in the reproductive organs.
What percentage of abnormal Paps are cancer?
The exact percentage of abnormal Paps that are cancer varies depending on the type of abnormal cell found on the Pap test. According to the Centers for Disease Control and Prevention (CDC), approximately 15–20% of abnormal Paps are associated with cervical cancer.
Pap tests can detect cervical pre-cancer, including lesions that could eventually lead to cervical cancer, but not all of these pre-cancerous cells will ultimately develop into cancer. Therefore, other sources suggest that the true percentage of abnormal Paps that are cancer could be lower than the 15–20% range reported by the CDC.
It is important to note that the Pap test is not a diagnostic test and is used to detect precancerous cells. Therefore, any abnormal Pap must be followed up with additional testing, such as a biopsy, to determine if the abnormal cells are cancerous.
A biopsy is the only way to accurately diagnose cancer and it is essential to determine a course of treatment.
How common is it for a Pap smear to be abnormal?
It is actually quite common for a Pap smear to show an abnormal result. According to the Centers for Disease Control and Prevention (CDC), at least 1 in 20 Pap smears result in a certain type of abnormal result called an “atypical squamous cells of undetermined significance” (ASC-US).
However, the exact rate of abnormal results will vary depending on factors such as the age of the woman being tested and the accuracy of the laboratory. In general, Pap smears are more likely to detect abnormal cells in women aged 30 or older.
In addition, most abnormal Pap smears are not reflective of an underlying health problem. In many cases, they merely indicate that there may be an issue present, and further tests will be required to determine its severity or if any treatment or action is necessary.
