TCT low-grade intraepithelial neoplasia is not contagious, while HPV56 positivity may be transmitted through sexual intercourse and other contacts. HPV56 positive belongs to high-risk human papillomavirus infection, which mainly invades human skin and mucous membranes, and may lead to cervical intraepithelial neoplasia in women, and long-term infection may even cause cervical cancer. It can be contracted through direct contact such as sex or indirect contact such as touching the patient’s clothes. TCT is a cervical liquid-based cytology, and its result of low-grade intraepithelial neoplasia suggests abnormal cervical cytology. It is recommended that further colposcopy or biopsy be performed to clarify whether there are cervical lesions or cervical cancer. For HPV56 positive, TCT low-grade intraepithelial neoplasia, colposcopy and pathologic biopsy are usually performed, and drug or surgical treatments are performed according to the results of the examination. During the treatment period, sexual intercourse should be avoided as much as possible to avoid cross-infection, and personal hygiene and care should be done well. After treatment, regular screening for cervical cancer should be carried out for early detection and early treatment. It is suggested that patients should go to hospitals for consultation in time and standardize the treatment under the guidance of doctors.
