What Are Cervical Polyps?
Cervical polyps are benign growths formed from excessive growth of the cervical canal lining. They typically resemble a finger or flower bud shape, are red or purple in color, range from a few millimeters to several centimeters in size, and may be pedunculated or sessile.
Cervical polyps are very common, especially in women aged 30-50 who have given birth. While most are benign, approximately 1-2% can become malignant, so they should not be taken lightly.
Causes of Polyp Formation
The exact cause of cervical polyps has not been clearly identified, but the following factors are believed to play a role:
Hormonal imbalance
Estrogen plays an important role in polyp development. When estrogen levels are elevated relative to progesterone, the cervical lining tends to overgrow, forming polyps. This explains why polyps are common in perimenopausal women.
Chronic inflammation
Prolonged cervicitis from bacterial, fungal, or other infectious agents stimulates abnormal tissue growth, creating conditions for polyp formation.
Other factors
- Cervical blood vessel blockage
- Abnormal hormonal response
- History of cervical procedures (curettage, cauterization)
Recognizing Symptoms
Many cases of cervical polyps have no obvious symptoms and are only discovered incidentally during routine gynecological exams. However, when polyps cause symptoms, women may notice:
Abnormal bleeding
- Intermenstrual bleeding: Spotting or light bleeding between periods
- Post-coital bleeding: The most common symptom, occurring when polyps are damaged during intercourse
- Postmenopausal bleeding: Requires special attention as it may indicate serious pathology
- Prolonged or heavier periods than normal
Abnormal discharge
- Yellow or white opaque discharge
- Foul-smelling discharge when polyps become infected
Difficulty conceiving
- Large polyps can obstruct the passage of sperm
- May affect embryo implantation
Diagnosing Cervical Polyps
Gynecological examination
Doctors can detect cervical polyps with the naked eye when inserting a speculum for vaginal examination. Polyps typically protrude from the cervical os, with a characteristic red or purple color.
Transvaginal ultrasound
Helps evaluate polyp size and location and differentiate from other conditions such as submucosal uterine fibroids.
Colposcopy
Uses magnifying optics to observe the polyp surface in detail, detecting signs of abnormality suggestive of malignancy.
Biopsy
Tissue samples are sent for pathological examination to determine whether the polyp is benign or malignant — this is a mandatory step after polyp removal.
When Is Surgery Necessary?
Not all cervical polyps require immediate surgery. The doctor will consider multiple factors:
Polyp removal is recommended when
- The polyp causes symptoms: Abnormal bleeding, pain, excessive discharge
- The polyp is large (over 1 cm) or growing
- The woman is trying to conceive or planning pregnancy
- The woman is postmenopausal — higher malignancy risk
- The polyp has abnormal appearance on colposcopy
- Abnormal Pap smear results
Monitoring may be appropriate when
- Polyp is small with no symptoms
- Young woman with no risk factors
- Follow-up every 6 months to monitor size
Polyp Removal Methods
In-clinic polyp removal
For small polyps with a clear stalk, the doctor can perform the procedure in the clinic:
- Stalk twisting: Using specialized forceps to twist and detach the polyp from its stalk
- Electrocautery: Cutting the polyp stalk with high-frequency electrical current
- Procedure time: 5-10 minutes
- No general anesthesia needed, local anesthesia may be used
- Patient goes home the same day
Hysteroscopy
Applied when polyps are deep within the cervical canal or uterine cavity:
- A small endoscopic camera is inserted through the cervix
- Direct visualization and precise polyp removal
- Local or brief general anesthesia
- Advantage: Complete removal with lower recurrence rate
Post-Removal Care and Considerations
First week
- Light bleeding or pink discharge is normal
- Mild cramping similar to menstrual pain may occur
- Take pain medication as prescribed
- Do not use tampons
Following 2-4 weeks
- Abstain from sexual intercourse
- No baths, swimming
- Gentle intimate hygiene with clean water
- No vaginal douching
Follow-up
- Return visit after 2-4 weeks
- Receive pathology results
- Confirm the removal site has healed properly
Do Cervical Polyps Recur?
The recurrence rate for cervical polyps is approximately 10-15%. To reduce recurrence risk:
- Thoroughly treat gynecological infections
- Balance hormones
- Regular gynecological checkups every 6 months
- Early detection if polyps recur
Differentiating Cervical Polyps from Other Conditions
Cervical polyps need to be differentiated from several conditions with similar presentations:
Endometrial polyps
Unlike cervical polyps that develop from the cervical canal lining, endometrial polyps grow from the inner uterine lining. Endometrial polyps typically cause heavier, longer periods and are harder to detect through routine examination, requiring ultrasound or hysteroscopy for diagnosis.
Submucosal uterine fibroids
Submucosal fibroids can protrude into the uterine cavity or through the cervix, resembling polyps. However, fibroids have a firmer smooth muscle structure, are usually larger, and show clearly different ultrasound images. Read more about uterine fibroids.
Cervical cancer
Some early-stage cervical cancers can appear as raised, protruding masses through the cervix, easily confused with polyps. This is why it is mandatory to send tissue samples for pathological examination after polyp removal. Women should have regular cervical cancer screening.
Cervical ectropion
Ectropion is a condition where glandular cells from the cervical canal are exposed on the outer surface, creating a red area around the cervical os. This differs from polyps but can also cause post-coital bleeding and excessive discharge.
Cervical Polyps During Pregnancy
Cervical polyps may be discovered during prenatal exams. In such cases, the doctor typically decides to:
- Monitor: If the polyp is small, asymptomatic, and not affecting the pregnancy
- Not remove during pregnancy: Unless the polyp causes heavy bleeding, as removal during pregnancy can increase risk of infection and bleeding
- Address after delivery: Polyps are usually removed and tested after birth
Cervical polyps rarely affect the delivery process, unless very large and obstructing cervical dilation.
When Should You See a Doctor?
You should see a gynecologist immediately if you experience:
- Bleeding after sexual intercourse — even once
- Intermenstrual bleeding or abnormal bleeding
- Postmenopausal bleeding — always requires examination to rule out malignancy
- Foul-smelling discharge, persistent yellow-green color
- Abnormally heavy periods lasting more than 7 days
- Difficulty conceiving after 12 months of trying
- Abnormal Pap smear results during routine screening
Don’t wait for symptoms to become serious — early detection leads to simpler and more effective treatment.

Advice From the Doctor
Dr. Lam advises: “In over 30 years of practice, formerly working at the National Cancer Institute, Hanoi Medical University Hospital, Hanoi Andrology Hospital, and Medlatec Hospital, I have managed many cervical polyp cases. Most polyps are benign, but don’t be complacent. Bleeding after intercourse or abnormal intermenstrual bleeding is a sign to see a doctor immediately. Polyp removal is a very simple, quick, and safe procedure. The important thing is to send the tissue sample for testing to rule out malignancy.”
Be proactive about regular gynecological checkups to detect and address any abnormalities early.
