Incidence
of Gynecologic Cancers
Information from the California
Department of Health Services, Cancer Detection Section
Nationally, the
most recent (2003) figures from the American Cancer Society (ACS) showed
that 83,700 women would be diagnosed with one of six gynecologic cancers:
ovarian, cervical, uterine, fallopian tubes, vagina, and vulva in the
next year.
The ACS figures
showed an expected 40,100 new cases of uterine cancer, 25,400 cases
of ovarian cancer and 12,200 of cancer of the cervix. Although ovarian
cancer ranks second among gynecologic cancers in the number of new cases
each year, it causes more deaths than any other cancer of the female
reproductive system.
In California, an
estimated 8,380 new cases and 2,635 deaths would be attributable to
gynecologic cancers, according to California Cancer Facts & Figures
(2003). It was projected these cancers would account for 13 percent
of all new cases of cancer and 10 percent of the cancer deaths among
California women in 2003.
Incidence rates
for cancer of the vulva, vagina, and fallopian tubes are very low. According
to ACS, in 2003 approximately 535 California women would be diagnosed
and 135 women would die from one of these three cancers.
The California Cancer Registry figures for the five-year period 1995-1999
indicate that the number of new cases of invasive gynecologic cancer
was highest for uterine (17,647), followed by ovarian (12,715) and cervical
(8,358). Of the six gynecologic cancers, uterine cancer had the highest
incidence at 43 percent and ovarian had the highest mortality at 54
percent.
Hispanic/Latina
women had the highest incidence of cervical cancer when compared to
all other ethnic groups. Mortality due to cervical cancer was disproportionately
higher among African American women compared to other ethnic groups.
Non-Hispanic white women had the highest incidence rates for uterine
cancer.
Effective screening
tools are available only for cervical cancer, while reliable diagnostic
procedures exist only for cervical and uterine cancers. The Pap test
is highly effective in detecting cervical cancer and its precursors,
but not for detecting the other five gynecologic cancers. Ovarian cancer
is difficult to detect early because when symptoms do occur, they are
often vague and may seem unrelated to the disease itself.
For this reason,
women are advised to know the warning signs for gynecologic cancers
and to have regular checkups that include a recto-vaginal pelvic examination
and a Pap test throughout their adult lives.
