Final answer:
According to ACS guidelines, the recommended cervical cancer screening protocol is a Pap smear and HPV testing every 5 years, starting at age 30 until age 65, provided previous tests were normal.
Step-by-step explanation:
The correct answer according to the ACS (American Cancer Society) guidelines for the testing for cervical intraepithelial neoplasia (CIN) and cervical cancer is Pap smear and HPV testing every 5 years. This is recommended for women starting at age 30 and can be done until age 65 if previous tests have been normal. The Pap smear alone should be performed every 3 years for women aged 21 to 29. Screening with HPV testing alone every 5 years is also acceptable starting at age 30. However, individuals who have had a complete hysterectomy or have a history of cervical cancer may require different screening schedules. It is essential to consult a healthcare provider for personal recommendations.
