Screening modalities like the Pap test and HPV test can help detect abnormal or precancerous cervical cells. The Pap test screens for cell changes and is recommended starting at age 21 and every 3 years. The HPV test screens specifically for the human papillomavirus, which can cause cell changes. For women over 30, both tests may be used. Certain groups are at higher risk for cervical cancer, including those with lower incomes or HIV/AIDS. While screening can help detect cell changes, both tests can produce false positives or negatives, so guidelines recommend less frequent screening to avoid unnecessary procedures. Treatment options depend on age and test results but aim to remove visible warts or abnormal cells.
