Learn about the common causes of Pap smear abnormalities

Pap smears are an important tool in cervical cancer screening, but many women feel anxious when the results are abnormal. Common causes of abnormal Pap smears include bacterial or viral infections, inflammatory reactions, and precancerous lesions of the cervix. Hong Kong obstetricians and gynecologists point out that the most common type of infection is HPV (human papillomavirus), especially high-risk HPV (such as HPV16 and 1 can cause abnormalities in cervical cells. Other infections, such as bacterial vaginosis or candida infections, can also affect smear results.

Inflammatory reactions are also a common cause. Inflammation of the cervix can cause changes in cell morphology and lead to false positive results. For example, chronic cervicitis can make cells look abnormal, but there is actually no risk of them becoming cancerous. Doctors suggest that if the smear results show inflammation, the infection can be treated first and then re-examined.

Cervical precancerous lesions (CIN) are classified into three grades: CIN1, CIN2, and CIN3. CIN1 is a mild lesion, usually caused by low-risk HPV, and about 60% resolve spontaneously. CIN2 and CIN3 are moderately severe lesions requiring further treatment. In Dr. Ao Zhangzhong's good reviews, many patients said that the detailed explanation of CIN grading helped them reduce their anxiety.

Inspection items after abnormal Pablo smear

If the results of the Pap smear are abnormal, the doctor will usually recommend further tests. Colposcopy is a common next step, which involves looking at the cervix through a magnifying glass and using acetic acid or iodine solution to highlight abnormal areas. Medical institutions in Hong Kong usually give detailed instructions in advance, such as avoiding sex 24 hours before the test and using vaginal medications.

A cervical biopsy (biopsy) is an important step in confirming the diagnosis. The doctor will take a small amount of tissue from the abnormal area for pathological analysis. The doctor said that a biopsy can cause mild discomfort and a small amount of bleeding, but usually does not require anesthesia. After the test, you should avoid strenuous exercise and sex for a few days.

An HPV DNA test can determine if you have high-risk HPV. According to data from the Hong Kong Health Bureau, about 15% of Hong Kong women are infected with high-risk HPV. During the discussion, some patients shared their experiences with HPV testing, emphasizing the importance of early detection.

How to treat abnormal results of varying degrees?

CIN1 is usually recommended for observational follow-up because it mostly resolves spontaneously. Your doctor recommends repeating the Pap smear or HPV test every 6-12 months. If abnormalities persist, topical treatments such as cryotherapy or lasers may be considered.

CIN2 and CIN3 require aggressive treatment. Cryotherapy destroys abnormal cells at low temperatures and is suitable for small lesions. Electrocautery (LEEP) uses an electric current to remove abnormal tissue. For larger lesions, colectomy (conical section) is a common option. Among the positive and negative reviews of Dr. Ao Zhangzhong, some patients mentioned his excellent LEEP technique and good recovery after surgery.

Post-treatment follow-up is very important. The Hong Kong Cancer Foundation recommends that the interval be reviewed every 3-6 months for the first year after surgery, and then the interval should be extended annually. Even if the results are normal, HPV can recur and should be screened regularly.

Factors affecting the results of Pap smears

Age is an important factor. According to data from Hong Kong, the HPV infection rate is high in women under 30 years of age, but most of it is temporary. The risk of persistent infection increases after the age of 30. Dr. Jiang Huizhong explained that after menopause, cervical cells atrophy due to a decrease in estrogen, which can affect the accuracy of smears.

Immunocompromised people (such as people with HIV or those who have been using immunosuppressants for a long time) are more likely to develop persistent HPV infection. Dr. Ao Zhangzhong once helped create personalized follow-up plans for immunocompromised patients.

Because nicotine can inhibit the immune response, lifestyle habits such as smoking can increase the risk of cervical cancer by 2 to 4 times. Polysexual partners and early sex are also risk factors. The Hong Kong Anti-Cancer Society recommends that reducing smoking and safe sex can reduce the chance of abnormal smears.

How to reduce the risk of abnormal Pap smears

HPV vaccination is the first preventive measure. The Hong Kong government has included the HPV vaccine in its school immunization program targeting high-risk types such as HPV 16 and 18. Dr. Jiang Huizhong emphasized that even if you are infected with one type of HPV, the vaccine can prevent other types of HPV.

Safe sex can reduce HPV transmission. Using a condom reduces the risk of infection by about 70%. In Dr. Ao Zhangzhong's health education materials, he specifically reminds us that even regular partners should pay attention to protection.

Quitting smoking is essential for cervical health. According to data from the Hong Kong Smoking and Health Council, the risk of cervical cell abnormalities begins to decrease one year after quitting smoking. In addition, a balanced diet (high intake of vitamins C, E, folic acid, etc.) can boost immunity and help eliminate the HPV virus.江慧中
