Cervical cancer - Epidemiology

Worldwide, cervical cancer is the second most common cancer in women (after breast cancer) and is the third leading killer (behind breast and lung cancer). It affects about 16 per 100,000 women per year and causes death in about 9 per 100,000 per year.

In the United States, however, cervical cancer is only the 8th most common cancer of women. About 12,800 women in the United States are diagnosed with cervical cancer and about 4,800 die each year (Canavan & Doshi, 2000). Among gynecological cancers it ranks behind endometrial cancer and ovarian cancer. The incidence and mortality figure for the U.S. are about half that of the rest of the world, a difference which can be attributed in part to the success of screening with the Pap smear.[2]

In Great Britain the incidence of cervical cancer has reached alarming proportions in that the mortality in England and Wales in women younger than 35 years rose three-fold from 1967 to 1987. In a study published in 2004 (Peto J et al) scientists from the London School of Hygiene and Tropical Medicine found that had it not been for effective cervical screening, one in 65 of all British women born since 1950 would have died from cancer of the cervix.

A study published in 2002 (Castellsagué et al) reports that male circumcision can reduce the risk of penile human papillomavirus (HPV) infection in the man, and as a result that of cervical cancer in his female partner. The authors do state that "it would not make sense to promote circumcision as a way to control cervical cancer in the United States, where Pap smears usually detect it at a treatable stage". In contrast to this claim, Menczer (2004) quotes research that male circumcision probably does not contribute to a lower incidence of cervical cancer in Jewish populations.
