Participants in both groups will undergo specific therapeutic procedures, including 5-ALA photodynamic therapy or CO2 laser treatment. The study will analyze and compare the effects of these therapies on the regression or elimination of cervical lesions, offering valuable insights into the management of persistent low-grade cervical lesions among high-risk HPV-infected women."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
