What to Know About Cervical Cancer

January is Cervical Cancer Awareness Month—a time to learn about the disease
and the importance of early detection as well as get screened. It is also a
time to celebrate that the mortality rate for cervical cancer has dropped by
50 percent in the past 40 years, which is attributed to the widespread use
of Pap smears.

“But this doesn’t mean that women should assume that their risk of
developing this type of cancer is so low that it isn’t worth worrying
about,” says Erika
Hamilton, MD
, Director of the Breast Cancer and Gynecologic Cancer
Research Program at Sarah Cannon Research Institute.

With that in mind, here are the top five facts you should know about cervical
cancer, all designed to help reduce your risk of developing the disease.

Fact #1: Cervical cancer is a “stealth” disease.

Unlike other forms of cancer that announce their presence with some kind of
physical indications, early cervical cancer (and its precursor conditions,
Cervical Intraepithelial Neoplasia, or CIN, Type 1 and Type 2) doesn’t come
with obvious symptoms. It is not usually until it has advanced to the point
where it has grown into other structures that warning signs, such as
abnormal bleeding between periods, abnormal discharge throughout the
menstrual cycle or any pain or bleeding during intercourse, can appear.

Fact #2: A Pap test is still the best “early warning” tool for
cervical cancer.

“It often takes quite a period of time before precancerous lesions turn into
cervical cancer,” says Dr. Hamilton. “A Pap smear can find precancerous
lesions before they become a cancer, which allows us to intervene and
prevent a cancer from developing. In the U.S. right now, the majority of
people diagnosed with invasive cervical cancer haven’t gotten routine
screening Pap smears which is evidence to the benefit of this screening
test.”

Fact #3: HPV is by far the greatest risk factor for cervical cancer.

While there are other risk factors that can increase your chances for
developing cervical cancer, HPV (human papillomavirus) is at the top of the
list. Among the more than 100 types of HPV, 13 types are considered
cancer-causing leading to 70% of cervical cancers worldwide. The test for
HPV can be done at the same time as the Pap test. If the test is positive,
your doctor will tell you what HPV type you have and recommend an
appropriate follow-up interval.

Fact #4: Two vaccines can protect against the types of HPV linked to
cervical cancer.

Gardasil®is approved
for women and girls ages 9 to 26 and  Cervarix®
is approved for women and girls ages 9 to 25. Gardasil® also
helps protect
boys and men against approximately 90 percent of genital warts cases. The
goal is to get vaccinated before you become sexually active in order to
prevent the types of HPV that cause cervical cancer.

“But while the vaccines protect against 70-80 percent of cervical cancers, it
doesn’t mean you can’t get some of the other types of HPV that aren’t
covered,” cautions Dr. Hamilton. “The vaccines are a form of risk reduction,
not a risk elimination.”

Fact #5: You and your doctor should decide together how often you need to
have a Pap test.

There is no magic age that is the cut-off point for Pap tests, says Dr.
Hamilton. Risk factors such as previous abnormal Pap results, your family
medical history, your number of sexual partners and recent sexual history,
even being overweight or a smoker can all increase the chances of developing
cervical cancer.

“And since the Pap test is still the best way to catch the disease in its
early stages or even before it develops from precancerous lesions,” she
adds, “your doctor may recommend that, in the presence of risk factors, you
continue to undergo a yearly Pap, before, during or even after menopause.”
