Why its Done?
A Pap smear is used to screen for cervical cancer. The Pap smear is usually done in conjunction with a pelvic exam. In women older than age 30, the Pap test may be combined with a test for human papillomavirus (HPV) — a common sexually transmitted infection that can cause cervical cancer. In some cases, the HPV test may be done instead of a Pap smear.
Risks:
A Pap smear is a safe way to screen for cervical cancer. However, a Pap smear isn't foolproof. It's possible to receive false-negative results — meaning that the test indicates no abnormality, even though you do have abnormal cells.
A false-negative result doesn't mean that a mistake was made. Factors that can cause a false-negative result include
- An inadequate collection of cells.
- A small number of abnormal cells.
- Blood or inflammatory cells obscuring the abnormal cells
