Pap Smear Introduction

Cancer of the cervix (cervical cancer) is the second most common cause of cancer-related disease and death among women worldwide. The best way to detect cervical cancer is by having regular Papanicolaou tests, or Pap smears. (Pap is a shortened version of the name of the doctor who developed the screening test.) A Pap smear is a microscopic examination of cells taken from the cervix.

A Pap smear can detect certain viral infections (such as human papillomavirus [HPV]) and other cancer-causing conditions. Early treatment of these conditions can stop cervical cancer before it fully develops. A woman may have cervical cancer and not know it because she may not have any symptoms.

The incidence of cancer and deaths from cervical cancer has significantly declined over the years because of prevention, screening, and early detection by the Pap smear. In the United States, about 2-3 million abnormal Pap smear results are found each year. Most of them indicate the early stages of disease and need reasonable observation by a doctor.

• Risks factors for cancer of the cervix include the following:

• Multiple sexual partners (or sexual partners who have had multiple partners)



• Starting sexual intercourse at an early age



• Viral infection, such as HPV, human immunodeficiency virus (HIV), or herpes simplex virus (HSV)



• Weakened immune system



• Previous cancer of the lower genital tract



• Smoking

Cervical cancer screening is recommended yearly starting when women are aged 18 years, or when they become sexually active if younger than 18 years. Physicians may screen a woman less frequently if she had negative Pap smear results 3 years in a row or is not sexually active.

No upper age limit for screening exists because the incidence of cancer of the cervix increases with age at a time when women may be less likely to get a Pap smear. Diagnosis of most of these cancers is in women older than 50 years. Even after menopause, a woman should continue to have regular Pap smears.

• The National Cancer Institute encourages women aged 65 years and older to get a Pap smear at least every 2 years (Medicare covers the cost), and every year if they are at higher risk and advised by their doctor. Many older women believe they no longer need Pap smears (and think they are not at risk for cervical cancer) because of their age, because they may not be sexually active, or because they have had a hysterectomy. That is not correct. These women need Pap smears because their risk is higher.

If a woman has had her uterus removed, she should still have yearly screening if there is a history of abnormal Pap smear results or other lower genital tract cancer.
