Introduction

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.

Generally, cervical lesions that are relatively small in scope and shallow in depth may be effectively treated with laser therapy, potentially achieving a cure. However, if the lesion is extensive or deeply infiltrative, laser treatment may not adequately eliminate all the affected tissue, making it difficult to completely cure the condition. It is recommended to visit a formal hospital and undergo treatment under the guidance of a qualified physician. Detailed explanation is as follows:

Laser treatment for cervical lesions primarily utilizes the photothermal effect of the laser to heat and coagulate the abnormal tissue, causing it to necrose and slough off, eventually being replaced by new healthy tissue. In general, laser therapy has a relatively high cure rate for mild cervical conditions such as cervicitis and cervical polyps. Low-grade cervical intraepithelial neoplasia (CIN) can also be effectively treated with laser therapy.

However, for lesions that are extensive or deep, laser therapy may sometimes fail to completely remove all abnormal tissue, thus carrying a risk of recurrence. In such cases, other treatment options, such as conization, may need to be considered.

Prior to undergoing laser treatment, patients should receive a comprehensive gynecological evaluation to determine the type and severity of the lesion. After laser therapy, patients should follow the physician's instructions to maintain cleanliness and dryness of the external genitalia, avoid sexual intercourse and tub bathing for a period of time, and schedule regular follow-up examinations.

Is laser therapy required for cervical lesions?

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.

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.
