<p>Cervical cancer remains one of the most prevalent gynecological malignancies worldwide, primarily caused by persistent infection with human papillomavirus. Despite advances in screening and vaccination, cervical cancer continues to be the second most common cancer among women, particularly in low- and middle-income countries, due to limited access to affordable and effective diagnostic and preventive tools. In addition to human papillomavirus, genetic mutations and epigenetic alterations play a crucial role in the transformation of normal cervical cells into cancerous ones. Emerging evidence highlights the significance of chromatin remodeling factors, which rely on regulatory signals for target specificity. Among these, PIWI proteins and their associated PIWI-interacting RNAs have been identified as key players in gene regulation and epigenetic modulation. These molecules are increasingly recognized for their role in cancer progression, metastasis, and recurrence. Furthermore, with the advent of liquid biopsy technologies, the demand for reliable and minimally invasive biomarkers has grown. PIWI proteins and piRNAs have shown promise as potential diagnostic and prognostic markers, capable of distinguishing between early and advanced stages of cervical cancer. This review highlights the functional relevance of the PIWI/piRNA pathway in cervical carcinogenesis and explores its potential application in the diagnosis, prognosis, and therapeutic targeting of cervical cancer. In conclusion, piRNAs and PIWI proteins play significant roles in cervical cancer development, progression, and stemness. They show promise as diagnostic and prognostic biomarkers and as novel therapeutic targets, but further research is required to translate these findings into clinical practice.</p>
