What is colposcopy?
Colposcopy is a technique used to examine the cervix and other organs in the pelvic region. During a colposcopy, a doctor will examine the cervix using a magnifying instrument called a colposcope. This procedure is performed with the cervix covered with a testing solution called a colposcopic dye. The dye will stain the cells and make them easier to visualize. The colposcopic dye helps to check any more pronounced abnormalities, such as lesions. A colposcopy may be performed at the same time as a Pap.What is a Pap test?
A Pap test checks for cell changes that may turn into cervical cancer. A colposcopy is performed simultaneously with a Pap test to look for changes on the cervix that can’t be seen with the naked eye.What causes HPV?
HPV is a virus genus that affects both men and women equally. The virus usually causes no symptoms, and most people are unaware they have it. A person can have HPV for years and not know it. HPV can induce alterations in the cervix's cells, vulva, vagina, anus, and other body areas. These changes can lead to cancer over time. The types of HPV that cause warts on the hands and feet or rough spots on the lips differ from those of HPV that cause abnormal cell changes in the cervix. Not all types of HPV cause changes in cells. Many patients infected with the virus are unaware that they are infected, and their bodies fight off the infection. Some types of HPV are more likely to cause cancer than others. HPV 16 and HPV 18 are the two types most likely to cause cancer. HPV can cause cervical cancer in two ways: precancerous lesions and cervical cancer.
What is the purpose of a colposcopy?
A colposcopy is used to see the cervix and other areas of the pelvic region with a colposcope. It is a diagnostic procedure used to investigate abnormalities of the cervix and vulva. During a Pap test, the cervix and other parts of the pelvic area may seem abnormal. Still, more testing is required to identify whether these changes are due to cell abnormalities or irregularities on the mucosal surface. A colposcopy allows a doctor to examine the cervix and other areas of the pelvic region at a much higher magnification than a Pap test. Allows for better identification of abnormal cells and their locations. The colposcopy is also used to identify any microabrasions that may have occurred during a Pap test. During a Pap test, the cervix is either scraped or a small brush is used to collect cells. This can cause microabrasions on the cervix. Identifying them helps determine the best follow-up treatment.What to expect during the colposcopy appointment
Before the colposcopy begins, the woman may be asked to change into a gown and empty her bladder. The woman will most likely be asked to lie on her back with her hips elevated and her knees slightly open. The doctor may apply a unique solution known as an acetic acid solution to help image any abnormal areas. This solution is applied to the cervix using a cotton swab. The answer may sting or burn. It may temporarily turn the room a shade of white or yellowish-white. A colposcopy is a unique magnifying instrument that uses light. The doctor will use it to look at the cervix and other areas of the pelvic region. The woman may be asked to cough or bear down to better view the cervix. The doctor may take a sample of cells from the cervix. This sample is sent to a laboratory for testing.How to prepare for a colposcopy
Women should do their best to stay hydrated and eat healthy before a colposcopy. This can make the procedure less uncomfortable and speed up the healing process. Before the colposcopy, women should take a warm bath or use a warm heating pad to help relax the pelvic area. Some women find it helpful to reduce discomfort by taking a mild pain reliever or anti-inflammatory medicine before the colposcopy. Cleaning the vulva and surrounding area is recommended before the colposcopy. Wiping the area with warm water and a mild soap should suffice. It’s also a good idea to avoid wearing deodorant or scented hygiene products, especially if the skin is broken. Pregnant women should consult with their doctor about when to get a colposcopy.How to interpret results from a colposcopy
The results of a colposcopy may be reported as positive or negative. The doctor may recommend a repeat colposcopy in a few years if they are negative. This is an excellent time to ask about HPV vaccination. Suppose the results are positive (i.e., abnormal cells identified). In that case, the doctor may recommend the following.Follow-up treatments:
A follow-up colposcopy: If the abnormal cells were located on the cervix's surface or walls, the doctor might perform a follow-up colposcopy to investigate the findings further. If the abnormal cells were inside the cervix, the doctor might perform a cone or LLETZ biopsy. A cone biopsy: During this procedure, the doctor uses a small scalpel to remove the abnormal areas on the cervix. This minor procedure can be performed in the doctor’s office. The doctor may use a local anesthetic or prescribe pain medication to ease discomfort. LLETZ biopsy: During this procedure, the doctor uses a narrow wire loop to remove the abnormal areas on the cervix. The coil is heated to destroy the cells. This procedure is also performed in the doctor’s office and can be done with local anesthesia.Possible follow-up treatments for abnormal colposcopy results
If the colposcopy reveals abnormal cells, the doctor may recommend a follow-up treatment to remove the cells. Women who have had a colposcopy and have a positive result should consult their doctor to explain the findings and discuss the next steps toward a healthy cervix. Women with an abnormal Pap test or who have had a colposcopy and are found to have abnormal cells may be prescribed a short course of antibiotics. This reduces the risk of infection, which can cause the abnormal cells to multiply and spread. Women with positive colposcopy results may be prescribed a short course of HPV medications.What to do after a colposcopy
After a colposcopy, the tissue may look inflamed or bruised. The patient should keep the area clean with warm water and use a pad to catch any discharge. If the doctor performs a biopsy, the woman may experience pain and discomfort in the pelvic region. Taking over-the-counter pain medicines as prescribed can help manage discomfort. taking lots of rest and drinking plenty of water is essential for the body's recovery. Some spotting or bleeding might occur if the biopsy is performed on the cervix. This is common and will vanish in a few days or a week. It’s essential to keep the area clean and avoid sexual activity until the bleeding subsides.Colposcopy risks
While many women have a colposcopy with no complications, there is always a small risk of infection, bleeding, or injury to the urethra, bladder, or other nearby organs. In addition, the disease risk is higher when an acetic acid solution is used.nGyn Cervical Screening System:
The nGyn colposcope assists in obtaining accurate cervical diagnoses. Its prescribed workflow reduces subjectivity and variability in colposcopies. AI-powered diagnostics act as guidelines for decision-making, enhancing the accuracy of the procedure.References:

What is the Pre-Screening for Cervical Cancer?
Read more
Cervical cancer is one of the most preventable cancers affecting women worldwide. Pre-screening involves tests designed to detect precancerous changes in the cervix, enabling timely intervention and reducing the likelihood of invasive cancer. These screenings are vital for protecting women's health, particularly in countries where cervical cancer is a leading cause of cancer-related deaths among women. This guide explains the importance of pre-screening, standard tests, preparation steps, and the benefits of early detection, supported by trusted references.
Why is Pre-Screening Important?
Pre-screening aims to identify abnormal or precancerous cells in the cervix before they develop into cancer. By catching these changes early, women can receive simple, effective treatments, preventing more complex and costly medical interventions later. According to the World Health Organization (WHO), cervical cancer is nearly always caused by persistent infection with high-risk human papillomavirus (HPV). Regular pre-screening reduces cancer incidence and saves lives by enabling early detection and treatment [1].
Common Cervical Cancer Screening Tests
Pap Smear Test
The Pap smear is one of the most widely used methods for detecting cervical abnormalities. It involves:- Using a speculum to widen the vagina for access to the cervix.
- Gently scraping cells from the cervix with a brush or spatula.
- Sending the collected cells to a lab for microscopic examination to detect abnormalities.
HPV Test
The HPV test is a molecular test that identifies high-risk HPV types known to cause cervical cancer. It can be done alone or alongside the Pap smear (co-testing). This test involves collecting a sample of cervical cells, which is then analyzed for the DNA or RNA of high-risk HPV types. WHO recommends HPV DNA testing as the most effective method for cervical cancer pre-screening [2].How to Prepare for Pre-Screening
Preparing for a cervical cancer screening can improve the accuracy of the results. Follow these tips:- Schedule the test when you are not menstruating.
- Avoid sexual intercourse, douching, or using vaginal products (like creams or medications) 48 hours before the test.
- Inform your healthcare provider about any recent health changes or symptoms.
Who Should Get Pre-Screened?
Screening guidelines vary based on age and individual health conditions:- Women aged 21–29 should undergo a Pap test every three years.
- Women aged 30–65 are advised to have either a Pap and HPV test every five years (co-testing) or a Pap test alone every three years.
- Women over 65 who have had regular screenings with expected results may no longer need screening unless they have a history of cervical pre-cancer [6].
Benefits of Early Detection
Early detection through pre-screening offers numerous advantages:- Higher Survival Rates: Early treatment is more effective and less invasive.
- Cost-Effective: Preventing advanced cervical cancer reduces healthcare costs.
- Quality of Life: Early intervention prevents women from aggressive treatments like surgery or chemotherapy.
Conclusion
Pre-screening for cervical cancer is a powerful tool for preventing one of the most common cancers in women. Regular tests like the Pap smear and HPV test can detect early changes in cervical cells, giving women the best chance for successful treatment. By understanding the importance and benefits of pre-screening, you can take a proactive step toward safeguarding your health.References

Symptoms of Advanced Cervical Cancer
Cervical cancer is a type of cancer that occurs in the cells of the cervix, which is the lower part of the uterus that connects to the vagina. It’s currently the second most common cancer cause of death among women in India. But it doesn’t have to be this way. When detected early, cervical cancer can be diagnosed and successfully treated long before symptoms occur. The pre-cancer and early cancer stages show no symptoms. Women are advised to undergo cervical cancer screening once every three years so that the disease can be detected at the earliest stages.
Once cervical cancer reaches advanced stages, symptoms begin to appear. This is when the disease grows into nearby tissue. While pre-cancer and early stage disease have no warning signs, the symptoms of advanced cervical cancer are wide-ranging. These symptoms overlap with many other diseases and disorders, so it’s always best to have proper screening done with a physician to identify the correct diagnosis.
Advanced stage cervical cancer symptoms:
Ignoring symptoms may allow the cancer to grow to a more advanced stage and lower the chance for successful treatment. The more frequently a woman is screened, the more likely it is for cervical cancer to be identified and treated at the earliest possible stage before there are any symptoms. With nGyn, physicians can skip the pap smear step and simply use the smart colposcope to quickly and precisely screen for cervical cancer. Results are immediate, making it possible to complete treatment in the same appointment. This efficiency makes it much easier to screen more women more frequently so that the disease doesn’t escalate to an advanced stage with pressing symptoms.

Advanced stage cervical cancer symptoms:
- Abnormal vaginal bleeding, including bleeding after vaginal intercourse, bleeding after menopause, or bleeding and spotting between periods
- An unusual discharge from the vagina, which may contain some blood and be heavy with a foul odor
- Pain during vaginal intercourse
- Pain in the pelvic region
- Swelling of the legs
- Problems urinating or having a bowel movement
- Blood in the urine

How Machine Learning Powers Smart ECGs
Read more
Across multiple disciplines, artificial intelligence (AI) in medical screening devices is helping improve patient outcomes by offering healthcare practitioners more nuanced ways to interpret data and make clinical decisions. AI assistance can play a critical role in detecting cardiovascular diseases earlier, which leads to earlier treatment and more precise outcome prediction and prognosis evaluation.
AI accomplishes this through a technique called machine learning by quickly analyzing massive amounts of data and sharing clinically relevant insights. This use of statistical algorithms identifies patterns in new data that match the patterns that have already been learned from existing data. The resulting predictions improves the quality, precision, and efficiency of healthcare.
To understand the different ways machine learning works, these are three subtypes of the technique based on the way the predictive model learns and accumulates data.
-
Supervised learning includes logistic regression, support-vector machines (SVMs), and neural networks. Models are developed using human-labeled datasets. These models find the most relevant variables to predict or classify future events and outcomes. Each new piece of data trains the predictive model, making it more robust over time.
-
Unsupervised learning includes cluster analysis. This method identifies new relationships within data by finding hidden structures in datasets that weren’t previously categorized in the training dataset.
-
Reinforcement learning involves reward-based learning and is typically used in gaming and robotic applications. This predictive model uses tools such as sensors, cameras, and GPS to help the machine understand the surrounding environment. The interactions with the environment guide the machine to continuously learn and improve.
These machine learning methods expand what’s possible in healthcare. For example, supervised learning algorithms can be used to classify heart rhythms. When AI powers an ECG, anomalies are automatically detected through a precise, quantitative assessment of cardiac functions. This removes variabilities that may skew results and reduces the time it takes to interpret the data, making appointments more efficient.
As AI further integrates into the cardiology world, physicians will be more and more empowered to improve their patients’ outcomes. The extra layer of intelligence augments the physician’s work, rather than replacing it. To learn more about how AI-driven ECGs can help detect cardiac abnormalities earlier, see nCardio.
