Cervical
Cancer: A Very
Preventable Disease
Excerpt

-- Every year, 15,000 American women are told they have cervical
cancer.
Worldwide, it's the second leading
cancer killer of women.
Yet most of these cases are preventable.
"Cervical cancer is preventable,"
says Dr. Steven R. Goldstein, a professor of obstetrics and gynecology
at New York University Medical Center.
The key, as with most cancers,
is early detection.
Ninety-eight to 99 percent of all
cervical cancers are caused by the human papillomavirus, or HPV.
The virus, which is sexually transmitted and comes in several
dozen different varieties, currently infects some 20 percent of
American adults. While most cases of HPV resolve on their own,
a small minority progress to cervical cancer, making it the biggest
health threat to this part of the female anatomy.
One of the problems with genital
HPV infections is that often they don't come with visible signs
and symptoms. A National Institute of Allergy and Infectious Diseases
study found that almost half the women infected with HPV had no
clear symptoms. What's more, people infected but who have no symptoms
may not know they can transmit HPV to others.
That's one reason why January has
been designated Cervical Health Awareness Month.
In November, researchers reported
in the New England Journal of Medicine that they had developed
a vaccine that had achieved a 100 percent success rate against
the version of the virus responsible for 50 percent of all cases
of cervical cancer. Despite these encouraging results, a workable
vaccine is still several years away.
For now, the best weapon against
cervical cancer is screening in the form of a Pap smear. And it's
very effective.
"If you look at mortality
from cervical cancer from the 1940s before we had the Pap smear
until the 1990s, there's a dramatic decrease," says Dr. Carolyn
D. Runowicz, vice chairman of the department of obstetrics and
gynecology at St. Luke's Roosevelt Hospital in New York City.
"The line is just a sharp
drop, so the Pap smear is absolutely, unequivocally a good example
of screening if done correctly," adds Runowicz, who is also
one of the authors of the American Cancer Society's cervical cancer
guidelines.
A Pap smear involves gently scraping
cells from the outside and the canal of the cervix. The cervix
is actually the "neck" of the uterus that protrudes
into the vagina and through which sperm and menstrual blood flow.
The test is easily done in a gynecologist's office as part of
a routine visit.
The problem is that not enough
women are getting screened, and most cases of cervical cancers
occur in unscreened women, Runowicz says.
"If we could get every woman
screened, we could eliminate this disease like polio," she
says. "Women sometimes think after their last baby, they
don't need to go to the gynecologist anymore. And they really
couldn't be more wrong -- and cervical cancer screening is one
reason among many."
Runowicz advises women to start
getting regular Pap smears within three years of becoming sexually
active but no later than age 21.
"Invasive cervical cancer
in this country is virtually unheard of before the age of 20,
but the individual woman needs to speak with her health-care provider
to determine what is an appropriate screening interval for her,"
she says.
"The cervix is a great organ,"
adds Goldstein. "You can Pap it, magnify it, biopsy it, cryo
it, laser it, look at it. It's not like the lung. There's no excuse
for any woman today to get cervical cancer."
So get screened.
