For unmarried women, if there is no sexual activity, they generally do not need to undergo cervical cancer screening. This is because the cause of cervical cancer has been clearly established as being caused by HPV virus infection, mainly transmitted through sexual contact. Therefore, unmarried women without sexual activity might not consider cervical cancer screening necessary. However, it is still recommended for unmarried women who are sexually active to undergo cervical cancer screening, especially if they started sexual activity at a young age and have multiple sexual partners. The screening generally includes HPV testing, cytology (TCT), and colposcopy.
