Introduction

Under normal circumstances, laser therapy may be required for cervical lesions that are of low grade, limited in extent, and in cases where fertility preservation is desired. However, if the lesion is of high grade or cervical cancer has been diagnosed, laser therapy is not recommended. Additionally, if the patient suffers from severe systemic diseases and cannot tolerate the trauma caused by laser treatment, laser therapy may lead to the spread of inflammation.

Generally, laser therapy may be required for cervical lesions that are low-grade, localized, and in cases where fertility preservation is desired. However, if the lesion is high-grade or cervical cancer has been diagnosed, laser therapy is not recommended. If there are any concerns, it is advisable to seek consultation at a reputable hospital in advance. Detailed analysis is as follows:

When cervical lesions are at a low grade and the affected area is relatively small, and the patient wishes to preserve her fertility, laser therapy can be considered. Laser treatment uses high temperatures to destroy abnormal tissue, causing low-grade, localized lesions to necrose and shed. Subsequently, healthy epithelial tissue will repair the affected area. This method is minimally invasive and aims to minimize impact on the normal structure and function of the cervix, helping preserve fertility and achieving good therapeutic outcomes.

If cervical lesions have progressed to high-grade squamous intraepithelial lesions with extensive involvement, or if cervical cancer has been diagnosed, laser therapy is not advised. High-grade lesions carry a high risk of malignancy, and laser treatment may not completely eradicate extensive lesions, leading to possible recurrence. Cervical cancer is a malignant disease, and laser therapy cannot provide a definitive cure.

In addition, if patients have severe systemic diseases making them unable to tolerate the trauma caused by laser treatment, or if there is acute genital tract inflammation present, laser therapy might cause the inflammation to spread. In such cases, laser therapy is also not recommended, and patients should follow their doctors' advice to consider alternative treatment options such as surgery, radiotherapy, or chemotherapy.

Can laser therapy cure cervical lesions?

Laser therapy for cervical lesions primarily utilizes the photothermal effect of laser light to heat the affected tissue, causing coagulation, necrosis, and subsequent shedding, which is then replaced by new, healthy tissue. Generally, laser treatment has a high cure rate for mild cervical lesions, such as cervicitis and cervical polyps. It is also effective for low-grade cervical intraepithelial neoplasia.

What are the important aspects of regular cervical examinations?

In general, the importance of regular cervical examinations includes early detection of cervical cancer and precancerous lesions, timely diagnosis of cervical inflammation, monitoring the progression of cervical lesions, increasing women's health awareness, and preventing other gynecological diseases. It is recommended that women begin regular cervical examinations at the age of thirty and establish an appropriate examination frequency based on individual circumstances and medical advice.

Is it necessary to undergo HPV and TCT tests?

In general, HPV testing refers to human papillomavirus testing, and TCT testing refers to thinprep cytologic test. These two tests are very necessary as they can clarify whether there is a viral infection and its type, promptly detect abnormal changes in cervical cells, more effectively identify high-risk populations for cervical lesions, and reduce the incidence and mortality of cervical cancer.
