Cervical dysplasia

Cervical dysplasia refers to abnormal changes in the cells on the surface of the cervix. These changes are not cancer, but they are considered precancerous, meaning they have the potential to develop into cervical cancer if left untreated. Cervical dysplasia is most often caused by infection with certain types of the human papillomavirus (HPV), particularly high-risk strains like HPV-16 and HPV-18.

Key Features of Cervical Dysplasia

  1. Cellular Changes: Cervical dysplasia is characterized by abnormal growth or changes in the cervical cells. The degree of dysplasia is classified based on how much of the cervical lining is affected:

    • Low-grade cervical dysplasia (CIN 1): Mild changes where only a small number of cells show abnormality. These changes often resolve on their own without treatment.

    • High-grade cervical dysplasia (CIN 2 and CIN 3): More severe changes where more of the cervical lining shows abnormal cells. These are more likely to progress to cervical cancer if left untreated.

  2. Human Papillomavirus (HPV) Connection: The main cause of cervical dysplasia is persistent infection with high-risk HPV. HPV is transmitted through sexual contact, and while most infections clear up on their own, some may persist and lead to cell changes.

​Symptoms of Cervical Dysplasia-Diagnosis

Cervical dysplasia typically does not cause any symptoms, which is why regular screening with Pap smears or HPV testing is critical for early detection. If symptoms do occur (which is rare), they may include:

​

  • Unusual Vaginal Discharge: In some cases, abnormal vaginal discharge may occur.

  • Spotting or Light Bleeding: Light bleeding or spotting between periods or after sexual intercourse can sometimes be a sign of cervical changes, though these symptoms are more commonly associated with advanced cervical disease.

​

Cervical dysplasia is usually detected during routine cervical cancer screening, which includes:

​

  1. Pap Smear (Pap Test): During a Pap smear, cells from the cervix are collected and examined under a microscope for abnormal changes. If abnormal cells are found, further testing may be needed.

  2. HPV Testing: This test checks for the presence of high-risk HPV strains that are known to cause cervical dysplasia and cervical cancer. It is often done in conjunction with a Pap smear.

  3. Colposcopy: If a Pap smear reveals abnormal cells, a colposcopy may be performed. This procedure involves using a special magnifying instrument to examine the cervix more closely. If areas of concern are found, a biopsy (sample of tissue) may be taken.

  4. Cervical Biopsy: A biopsy is the definitive way to diagnose cervical dysplasia and determine its severity (CIN 1, CIN 2, or CIN 3).

​Causes and Risk Factors

Cervical dysplasia is most strongly linked to persistent infection with high-risk HPV strains, but other factors can also increase the risk of developing the condition:

​

  • HPV Infection: Particularly the high-risk types, HPV-16 and HPV-18, are the main cause of cervical dysplasia.

  • Multiple Sexual Partners: A higher number of sexual partners increases the risk of HPV infection.

  • Weakened Immune System: Women with compromised immune systems (e.g., due to HIV/AIDS or immunosuppressive medications) are more prone to developing cervical dysplasia.

  • Smoking: Tobacco use has been shown to increase the risk of cervical dysplasia.

  • Early Onset of Sexual Activity: Becoming sexually active at an early age increases the likelihood of contracting HPV, which can lead to cervical dysplasia.

  • Long-term Oral Contraceptive Use: Prolonged use of birth control pills may slightly increase the risk of cervical dysplasia.

Treatment and Follow-up Care

The treatment for cervical dysplasia depends on the severity of the cell changes and other factors like the patient’s age, overall health, and desire to preserve fertility.

1. Observation:

  • Low-Grade Dysplasia (CIN 1): Often, mild cases of cervical dysplasia will resolve on their own, especially in younger women. In such cases, doctors may recommend watchful waiting, with regular follow-up Pap smears and HPV tests to monitor any changes.

2. Surgical Treatments:

  • Cryotherapy: A procedure that freezes and destroys abnormal cervical cells. It is typically used for mild to moderate dysplasia.

  • Loop Electrosurgical Excision Procedure (LEEP): Uses a wire loop heated by electric current to remove abnormal tissue from the cervix. It is often used for moderate to severe dysplasia.

  • Cone Biopsy (Conization): Involves removing a cone-shaped piece of abnormal tissue from the cervix. It is used for more severe dysplasia or when there is a concern about possible early-stage cancer.

  • Laser Therapy: Uses a high-energy light beam to remove or destroy abnormal cells.

​

​Women who have been treated for cervical dysplasia need regular follow-up Pap smears or HPV tests to ensure that the abnormal cells do not return. This is especially important for women with high-grade dysplasia, as there is a higher risk of recurrence.

Complications-Prevention

  • Progression to Cervical Cancer: High-grade cervical dysplasia (CIN 2 or CIN 3) that is not treated can progress to invasive cervical cancer over time. This progression can take years or even decades, but it emphasizes the importance of regular screening.

  • Recurrence: Even after treatment, cervical dysplasia can recur, particularly in women with persistent HPV infection.

  • Fertility Issues: Some treatments for severe dysplasia, like LEEP or cone biopsy, can weaken the cervix, increasing the risk of preterm labor in future pregnancies. However, most women treated for cervical dysplasia can still have healthy pregnancies.

​

Cervical dysplasia can often be prevented through various measures:

​

  • HPV Vaccination: The HPV vaccine (such as Gardasil or Cervarix) is highly effective at preventing infection with the high-risk HPV types that cause cervical dysplasia and cervical cancer. The vaccine is most effective when given before a person becomes sexually active, typically around ages 11 to 12.

  • Regular Screening: Routine Pap smears and HPV testing can detect cervical dysplasia early, allowing for treatment before it progresses to cancer.

  • Safe Sexual Practices: Using condoms and limiting the number of sexual partners can reduce the risk of HPV infection.

  • Smoking Cessation: Quitting smoking can lower the risk of developing cervical dysplasia, as smoking weakens the immune system and makes it harder for the body to clear HPV infections.

Long-Term Outlook:

With early detection and proper treatment, cervical dysplasia is highly treatable and preventable. Most women who receive regular screenings and follow treatment recommendations will not develop cervical cancer. However, ongoing monitoring is essential to ensure that abnormal cells do not return or progress.
