Cervical biopsy

In modern gynecology, there are many diagnostic methods that can detect pathologies at early stages. One of the most informative procedures is cervical biopsy - microsurgery, which helps to accurately assess the condition of the cells and tissues of the organ. Thanks to this method, it is possible to examine the slightest changes that cannot be seen during a regular examination or colposcopy.

Indications for cervical biopsy

A biopsy is prescribed if there are signs or test results that indicate a suspected pathology. For women preparing for the programs IVFIt can also be an important step in checking the health of the cervix before starting stimulation. The procedure is not done "just for fun". There are clear indications when a biopsy is necessary:

  • Abnormal results of cytological screening (PAP test). If the cytology revealed atypical cells, histological confirmation is required to determine the extent of the changes.
  • Positive test for high-risk HPV (human papillomavirus) types. Infection with oncogenic strains of HPV increases the risk of cervical dysplasia and cancer - a biopsy determines the presence of tissue changes.
  • Suspicious visual changes during a gynecological examination or colposcopy (gynecological examination with an optical device). Mosaic structure, white areas of tissue during the iodine test, atypical blood vessels, etc. are the grounds for conducting cervical biopsy.
  • Indeterminate or repeated bleeding. Intermenstrual bleeding, bleeding after sexual intercourse and other contact bleeding require the exclusion of structural pathology.
  • Polyps, long-standing erosion, papillomas, leukoplakia, dysplasia, ectopia, condylomas, uterine fibroids, chronic endocervicitis. To determine the nature of the pathology (benign or malignant), a sample is taken for histology.
  • Discrepancy between the clinical picture and the results of previous tests. If there is a discrepancy between the colposcopic image and cytology, a biopsy helps to dispel doubts.
  • The need to monitor the condition of the cervix after treatment.

Each indication is a reason to obtain a histological report that will influence further tactics.

Contraindications to cervical biopsy

Although the procedure is not a serious intervention and is safe, there are situations when a cervical biopsy it is better to postpone. There are absolute and relative contraindications:

  • Acute infections of the genital tract or pelvic organs - the risk of inflammation spreading and worsening symptoms.
  • Active bleeding or severe anemia - a biopsy can worsen the condition.
  • Menstruation - complicates the examination and increases the risk of infection.
  • Blood clotting disorders are a risk of severe bleeding.
  • Recent invasive interventions on the cervix (e.g., conization) - wait for healing.
  • Pregnancy - in most cases, a biopsy is postponed or performed only in threatening cases.
  • Any systemic disease accompanied by fever (ARVI, etc.).

For each patient, the doctor assesses the risk and makes a decision on the procedure.

Types of cervical biopsy

Modern gynecology offers several methods of sampling, each of which has its own advantages and indications. The choice depends on the localization of suspicious changes, their depth, the results of cytology, colposcopy, and the patient's general condition.

Targeted biopsy of the cervix

The most common type of biopsy. It is performed under the visual control of a colposcope - a special magnifying device. The doctor identifies a suspicious area and takes a small piece of tissue from it using forceps or another instrument.

Targeted cervical biopsy is prescribed in case of:

  • detection of localized, clearly visible pathological changes during colposcopy;
  • the presence of areas with severe atypia;
  • cytology results indicating dysplasia;
  • when the lesion is superficial and does not affect deep layers.

The procedure is characterized by minimal trauma, high sampling accuracy, and a short recovery time (usually a few days). However, if there is a suspicion that the process is spreading into the cervical canal or has a significant depth, other methods are required.

Endocervical curettage

The procedure is prescribed when suspicious changes are observed not in the outer part of the cervix, but in its canal. Using a special instrument (curette), the doctor gently "scrapes" the surface cells from the walls of the cervical canal. The obtained material is sent for histological examination. Endocervical curettage helps to evaluate and detect the slightest changes in the epithelium inside the cervical canal, an area that is not directly visible during colposcopy. This is an indispensable method in case of endocervical pathology, when the transformation border is shifted inside the canal and is not available for targeted biopsy, as well as in case of questionable cytology results.

Excisional biopsy (conization)

This is a diagnostic and therapeutic procedure during which a cone-shaped fragment of cervical tissue is surgically removed. The excised cone covers the entire suspicious area along with adjacent healthy areas and part of the cervical canal, which allows for the most accurate assessment of the spread of the pathological process.

During conization, the tissue can be removed with a scalpel (knife conization), a laser, or a radio wave method. The latter two options provide more precise control over the depth of excision and less blood loss. The resulting sample is then thoroughly examined histologically, which allows us to determine not only the nature of the lesion, but also the degree of dysplasia, the presence of preinvasive or microinvasive cancer, and the cleanliness of the resection margins.

The procedure is performed in case of severe cervical intraepithelial neoplasia, suspected microinvasive carcinoma, and when the results of colposcopy, cytology, or targeted biopsy are contradictory or insufficiently informative. Conization is both a diagnostic and treatment method, as removal of pathologically altered tissue may be sufficient to completely eliminate the dysplasia.

Despite its high information content, the procedure is more traumatic than a targeted biopsy. It can shorten the length of the cervix, which in some cases affects its function and increases the risk of obstetric complications in the future. However, if indicated, conization remains the optimal method for diagnosing and timely treating precancerous conditions.

Radio wave biopsy of the cervix

A modern, minimally traumatic method that uses a device that generates high-frequency radio waves. Under their influence, the incision is made with a special radio wave electrode (radio knife), which provides precise and controlled excision of the pathologically altered area. Targeted removal of tissue occurs without significant heating, evaporation or charring, so the sample retains its structure and suitability for high-quality histological examination.

This method is characterized by minimal bleeding, as radio waves simultaneously coagulate small blood vessels, which reduces the risk of post-procedure complications. Due to the gentle effect and the absence of rough scarring radio wave biopsy of the cervix has a short recovery period and is well tolerated by patients. It is considered the best option for women planning a pregnancy in the future, as it has virtually no effect on the density and length of the cervix, while maintaining its functionality.

Preparation and/or course of the procedure

Proper preparation reduces the risk of complications and helps to obtain correct results. Before a biopsy, you need to:

  • Undergo all recommended examinations: PAP test, tests for HIV, hepatitis, RW, Pap smear and infections, blood tests (general, biochemical, coagulation).
  • Avoid sexual intercourse for 48 hours before the procedure.
  • Do not use any vaginal products (suppositories, creams, tampons) 48 hours before the specimen collection.
  • Do not drench.
  • Schedule the procedure for the 7-10th day of the menstrual cycle (optimal time for visualization), unless there are emergency indications.
  • Discuss with your doctor the presence of allergies (if any) and the use of medications, especially anticoagulants and drugs that affect blood clotting.

How a cervical biopsy is performed

Although the procedure may seem complicated, in practice it takes 5-20 minutes, and most women tolerate it comfortably. It does not require anesthesia or is performed with local anesthesia.

  1. Preparation of the patient. The doctor explains the procedure, answers questions, and obtains written informed consent.
  2. Positioning on a gynecological chair. The woman lies on her back, her legs are on special supports.
  3. A gynecological examination and antiseptic treatment of the external genitalia is performed to minimize the risk of infection.
  4. Insertion of the mirror. A gynecological mirror is inserted into the vagina for better visualization of the cervix.
  5. Colposcopy. The doctor examines the cervix under magnification, applies special solutions that enhance the visibility of suspicious areas. This helps to perform a targeted biopsy.
  6. Local anesthesia. If necessary, the cervical area can be irrigated with lidocaine solution or anesthetic is injected.
  7. Material collection. Depending on the type of biopsy, forceps, curette, radio knife, etc. are used - it can be a small "pinch" or a larger amount of tissue. During the procedure, a woman may feel mild pressure, tingling, and short-term pain.
  8. Bleeding control. Electrocoagulation, hemostatic solutions, or radio wave exposure are used, after which a tissue healing agent is applied to the intervention area.
  9. The obtained sample is immediately placed in a sterile container - proper fixation is critical for accurate histological analysis.
  10. Post-procedure monitoring. The patient remains under observation for 10-30 minutes. The doctor provides recommendations for recovery and sets a date for a follow-up examination.

Knowing what a cervical biopsy is You can guess that after such an intervention, there may be slight bloody or watery discharge, mild discomfort in the lower abdomen, or mild pulling sensations, like during menstruation. This is all considered normal if it lasts no longer than a week.

Depending on the examination, diagnostic options are possible:

  • Negative result. The cervical tissue has a normal structure or only minor inflammation is detected. In this case, the doctor usually chooses a follow-up tactic: treatment of the inflammatory process (if necessary) and repeated examination after a certain time.
  • Low-grade dysplasia. These are early cell changes that are often reversible. Conservative treatment is usually prescribed in combination with observation and control of HPV, as human papillomavirus is often associated with such changes.
  • High-grade dysplasia. In this case, cellular changes are more pronounced and have the potential for progression. Doctors usually recommend more radical tactics - excision or conization of the cervix to completely remove the affected area and prevent the development of oncology.
  • Microinvasive/invasive cancer. With such a result, the patient is referred for further comprehensive oncological examination to determine the stage of the process, additional tests or instrumental studies. Treatment is carried out according to special protocols that may include surgery, radiation or chemotherapy.

The accuracy of the conclusion depends on the quality of the sample taken and the correctness of its fixation. Therefore, it is better to undergo the procedure in reliable clinics with experienced specialists and modern equipment.

Rehabilitation period after cervical biopsy

The duration of recovery depends on the scope of the intervention, the method, and the individual characteristics of the body. For example, in case of targeted or radio wave biopsy, it takes 3-10 days, while in case of conization, healing can last up to 6-8 weeks.

To speed up the rehabilitation period, you need to follow the doctor's recommendations:

  1. Abstain from sexual intercourse for 2 weeks or as directed by a doctor.
  2. Do not use tampons for 2-4 weeks.
  3. Do not use vaginal products without a doctor's prescription.
  4. Avoid baths, saunas, and swimming pools for at least 1-2 weeks.
  5. Do not lift heavy objects and avoid intense sports for the first 1-2 weeks.
  6. If necessary, take painkillers as recommended by your doctor (but not aspirin).
  7. Maintain hygiene - a shower instead of a bath.
  8. Consult a doctor in case of fever, increased pain, heavy bleeding, or discharge with an unpleasant odor.
  9. Do not plan pregnancy immediately after the procedure - you need to wait until the cervix is completely healed.
  10. Quit smoking and alcohol to improve microcirculation and accelerate tissue regeneration.

Following these rules helps you recover faster and avoid complications.

Features and interesting facts

Possible complications and risks

Mostly cervical biopsy goes without complications, but like any intervention, the procedure can have risks. Below are the most common ones.

Bleeding

It can occur immediately or during the first days after the procedure. It is more common in women with blood clotting disorders, anemia, anticoagulants, or when a large tissue excision is performed. Usually, the bleeding is minor and stops on its own, but heavy discharge requires immediate examination by a doctor.

Inflammation of the cervix

It develops rarely, usually in case of non-compliance with recommendations after a cervical biopsy. For example, in case of early return to sexual activity, visiting the swimming pool. Symptoms may include the appearance of an unpleasant odor of discharge or its visual changes (color, consistency), fever, pain in the lower abdomen. A timely visit to a specialist can quickly eliminate the infection.

Pain

In most women, the pain is moderate and lasts for a short time - from several hours to 1-2 days. It may resemble the sensations during menstruation. In case of hypersensitivity, short-term cramps are possible. If necessary, your doctor may recommend mild painkillers.

Long-term discharge

A watery or lightly bloody discharge for a few days is normal. However, prolonged, heavy, or heavy bleeding may indicate a superficial defect that heals more slowly or tissue irritation. It is also important to see a doctor if the discharge is disturbing and uncomfortable.

Cervical insufficiency

Shortening the length of the cervix, for example, in the case of conization, can potentially affect the gestation of future pregnancies - increasing the risk of miscarriages and premature birth.

Damage to the neck with scarring

This is a rare complication that occurs more often after more aggressive, deep biopsy methods. A pronounced scar can affect the elasticity of the cervix or its patency. However, modern technologies significantly reduce the likelihood of such consequences by providing delicate tissue excision.

Psycho-emotional stress

Some women experience anxiety, tension, or insomnia before the procedure or while waiting for the result. It's important to get clear explanations from your doctor and not to panic - this will help reduce emotional stress and make the procedure easier.

To minimize the risks, you should entrust the procedure to an experienced specialist who is familiar with modern methods and their features.

Frequently asked questions about cervical biopsy

Is it possible to have a cervical biopsy for those who have not given birth?

Yes, the procedure is safe for women who do not yet have children. In such cases, targeted or radio wave biopsy is most often performed. The latter method is especially appreciated for its minimal risk of scarring, so it is most often recommended for young women planning a pregnancy in the future.

Does a biopsy affect the ability to get pregnant?

For the most part, no. Standard, minimally traumatic biopsy techniques do not affect fertility, as the structure of the cervix is not significantly disturbed. However, extensive excisional interventions can slightly change the length of the cervix and increase the risk of premature birth or miscarriage in the future. However, these situations are not really related to biopsy, but to treatment interventions. Doctors always choose a method based on the patient's reproductive plans.

How much does a cervical biopsy cost?

The cost of the procedure depends on the method, clinic, and the need for additional tests. It is better to check the total price in a particular medical center, because often the cost of histology is calculated as a separate procedure. У At the fertility clinic in Kyiv "At IVMED, a cervical biopsy (histological examination, not excisional) costs UAH 1,240, and an excisional histological examination costs UAH 1,565.

When will the results be ready?

The standard histological examination period is 5-14 days. However, in urgent cases, an accelerated examination can be performed, but this requires approval and additional payment.
