It is estimated that there will be about 1,350 new cases of
cervical cancer in Canada in 2006.1 Cervical cancer is the second most common type of cancer in
women worldwide.2 It usually affects women older than
40.
About half of women diagnosed with cervical cancer have never had a
Pap test. Another 10% of women diagnosed with invasive cervical cancer have not
had a Pap test in the last 5 years. Women in Canada with the highest risk for
not having a Pap test or for not having routine Pap tests include:3, 4
- Older women, especially those 40 and
older.
- Aboriginal women.
- Women who recently immigrated
to Canada.
- Low-income women, especially those who live in rural
areas.
The most significant risk factor for developing cervical cancer is a
persistent infection with a high-risk type of the
human papillomavirus (HPV).
Being infected with a high-risk type of HPV or having other risk
factors increases the chance that a woman with an HPV infection will develop
abnormal cervical cell changes that may need further treatment.
The incidence of cervical cancer has decreased in developed
countries around the world because of an increase in the use of Pap test
screening and appropriate follow-up treatment. In developing countries, the Pap
test is not as readily available as it is in more developed countries. Because
of this, abnormal cervical cell changes in women who live in developing
countries may progress to cervical cancer without the benefit of detection and
treatment.
