What is the primary purpose of a Pap smear?

The primary purpose of a Pap smear is to screen for cervical cancer. This routine test involves collecting cells from the cervix to detect any abnormal changes that may indicate the presence of precancerous lesions or cervical cancer itself. Early detection through a Pap smear can lead to timely intervention, significantly reducing the morbidity and mortality associated with cervical cancer.

While other options like testing for pregnancy, diagnosing sexually transmitted infections, or evaluating menstrual irregularities are important aspects of women's health care, they are not the focus of a Pap smear. Pregnancy tests involve hormonal assessments rather than cellular evaluation, sexually transmitted infections are diagnosed using specific tests for pathogens, and menstrual irregularities typically require a different diagnostic approach, such as history-taking and additional imaging or hormonal studies. In summary, the spotlight of the Pap smear is on cervical cancer screening, making it a critical component of preventive health care for women.
