A Pap smear (Pap test) is a test of a sample of cells taken from a woman's cervix. The test is used to look for changes in the cells of the cervix that show cervical cancer or conditions that may develop into cancer.

It is the best tool to detect precancerous conditions and hidden, small tumors that may lead to cervical cancer. If detected early, cervical cancer can be cured.
