Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.
Incidence and Mortality
Estimated new cases and deaths from cervical (uterine cervix) cancer in the United States in 2013:
New cases: 12,340.
The prognosis for patients with cervical cancer is markedly affected by the extent of disease at the time of diagnosis. A vast majority (>90%) of these cases can and should be detected early through the use of the Pap test and human papillomavirus (HPV) testing; however, the current death rate...
The risks of cervical cancer screening include the following:
False-negative test results can occur.
Screening test results may appear to be normal even though cervical cancer is present. A woman who receives a false-negative test result (one that shows there is no cancer when there really is) may delay seeking medical care even if she has symptoms.
False-positive test results can occur.
Screening test results may appear to be abnormal even though no cancer is present. Also, some abnormal cells in the cervix never become cancer. A false-positive test result (one that shows there is cancer when there really isn't) can cause anxiety and is usually followed by more tests and procedures (such as colposcopy, cryotherapy, or LEEP), which also have risks. The long-term effects of these procedures on fertility and pregnancy are not known.
Women aged 20 to 24 are most likely to have abnormal Pap test results that lead to further testing and treatment. HPV DNA tests find many infections that will not lead to dysplasia or cervical cancer, especially in women younger than 30 years.
Your doctor can advise you about your risk for cervical cancer and your need for screening tests.
Studies show that the number of cases of cervical cancer and deaths from cervical cancer are greatly reduced by screening with Pap tests. Many doctors recommend a Pap test be done every year. New studies have shown that after a woman has a Pap test and the results show no sign of abnormal cells, the Pap test can be repeated every 2 to 3 years.
The Pap test is not a helpful screening test for cervical cancer in the following groups of women:
Women who are younger than 25 years.
Women who have had a total hysterectomy (surgery to remove the uterus and cervix) for a condition that is not cancer.
Women who are aged 60 years or older and have a Pap test result that shows no abnormal cells. These women are very unlikely to have abnormal Pap test results in the future.
The decision about how often to have a Pap test is best made by you and your doctor.
