• Rationale and Comments

    There is a slight increase in cancer risk by increasing the interval between screens. However, this risk is balanced with potential harm from more colposcopy as a result of spurious HPV infection that, in most women, will clear spontaneously and is unlikely to progress to any clinically relevant cervical disease. Based on modeling studies of three- or five-year intervals, the screening intervals should be greater than a year, but the current evidence does not support a longer screening interval than three years for cervical cytology with HPV triage or for primary HPV screening with cytology triage.
