Name a common screening tool used in women's health for detecting cervical cancer.

The Pap smear is a widely recognized and commonly utilized screening tool for detecting cervical cancer in women's health. This test involves collecting cells from the cervix and examining them for abnormalities that may indicate the presence of cervical cancer or precancerous changes. The effectiveness of the Pap smear lies in its ability to catch any abnormal cellular changes early, allowing for timely intervention and treatment, significantly improving outcomes.

In contrast, mammograms, while crucial for breast cancer screening, do not detect cervical cancer. Pelvic ultrasounds serve to visualize pelvic organs but are not specific for cervical cancer screening. Similarly, transvaginal biopsies are diagnostic procedures used to evaluate lesions or abnormalities already identified but are not employed as a screening tool. Therefore, the Pap smear stands out as the specific and appropriate answer for cervical cancer screening in women's health.
