Summary
Brief summary (as posted)
Non-classified atypical squamous cells (ASCUS) is the most common abnormal cervical cytology (%39). The risk of cervical intraepithelial neoplasia 2-3 is 5% and the risk of carcinoma is around 0.1% after diagnosis. Mostly human papillomavirus (HPV) is responsible for this transition. Most of them are transient, but some infections become persistent and can progress into precancer and invasive cancer. In the process of progression to cancer; patients with cell cycle problems are thought to be at risk. In some studies, B12 and folate deficiency, which play a role in DNA synthesis and repair, have been shown to induce incorrect binding of uracil to DNA, leading to DNA breakage and repair disorder. Therefore, in this study, it has been aimed that the relation of presence of atypical squamous cells and HPV persistence with folate and vitamin B12 levels which effect on immune system.
