Based on the information you provided, you have one or more risk factors for cervical
cancer. A risk factor is any condition or behavior that increases your likelihood
of developing a disease. Still, having a risk factor does not mean you will develop
a disease. Knowing what your risk factors are helps you and your healthcare provider
decide on the best screening schedule. It also helps you find things you can change
to help lower your risk for cervical cancer.
For cervical cancer, the primary risk factor is infection with certain high-risk types
of HPV (human papillomavirus). Other secondary risk factors also come into play. Based
on the answers you provided, your risk factors, if any, are listed below.
Understanding risk factors for cervical cancer
The most important risk factor for cervical cancer is being infected with HPV (human
papillomavirus). Most women diagnosed with cervical cancer have had this virus. HPV
is passed on through skin contact with an infected part of the body, usually on or
near the sexual organs. Your risk of getting this virus increases if you have sex
at an early age, if you have had many sexual partners during your lifetime, or if
your partner has had many sex partners.
HPV refers to a group of more than 150 types of viruses. Some of these are low risk.
They cause genital warts. But a few HPVs cause cervical cancer. In fact, about two-thirds
of all cervical cancer cases are caused by only two types, HPV 16 and HPV 18. Still,
most women who are infected with these types of HPV don't develop cervical cancer.
In most people, the body can get rid of the infection on its own.
HPV infection doesn't often cause warts or other symptoms, so you can have it and
pass it to another person without knowing it. Condoms protect against many sexually
transmitted infections (STIs), but they don't offer total protection against HPV.
This is because HPV can be passed on by any skin contact with an infected area of
the body that can't be covered with a condom. Even when no warts are present, HPV
can stay in the skin and be passed on.
A vaccine for HPV is available for people between ages 9 and 65. The CDC advises
that all people through age 26 get the vaccine. Ideally, the vaccine should be given
before a person becomes sexually active. It's a preventive vaccine. It does not protect
people who have already been exposed to HPV. Still, there may be some benefit in women
already exposed to some strains of HPV, because the vaccine is directed against 9
strains and may protect against future exposure to these other strains. People ages
27 to 45 should talk with their healthcare provider about their risk for new HPV infection
and the possible benefits of the vaccine.
According to the American Cancer Society (ACS), other factors that increase your risk
for cervical cancer are:
- HIV infection or a weak immune system. HIV is the virus that causes AIDS. It damages the body's immune system. HIV and
any other condition that weakens the immune system puts a woman at greater risk for
HPV infection. An example of a condition that weakens the immune system is taking
medicines to suppress your immune system after organ transplant or to treat autoimmune
disease. This may increase the risk for cervical cancer.
- Chlamydia. Chlamydia is a common STD with few symptoms. Recent research suggests that a past
or current chlamydia infection may put a woman at greater risk for cervical cancer.
- Family history of cervical cancer or cervical dysplasia. Women whose mother or sisters have had cervical cancer or cervical dysplasia are
at greater risk themselves for cervical cancer. This may be because some women inherit
a condition that makes them less able to fight off HPV infection.
- Smoking. Women who smoke are about twice as likely as nonsmokers to get cervical cancer. Tobacco
smoke contains many cancer-causing chemicals that are carried throughout the body
in the blood. Some of these chemicals have been found in the cervical mucus of women
who smoke.
- Poor diet. Women who eat few fruits and vegetables may be at higher risk for cervical cancer.
- Not getting regular screening. Regular screening with Pap or HPV tests allows cervical cell changes to be found
and treated before they become cancer. Most cervical cancers are found in women who
never been screened or haven’t been screened regularly.
The importance of screening
The increased use of the Pap test has greatly reduced deaths from cervical cancer.
Pap tests find early cancers and changes in the cells of the cervix that could lead
to cancer. Cervical cancer develops slowly. It usually takes years to progress from
a precancerous change to cancer. For many women, the precancerous changes don't progress
to cancer. Some will go away without any treatment. But precancerous conditions can
also be treated. Preventing cancer from developing is key. Routine screening makes
this possible.
Here are the ACS guidelines for cervical cancer screening:
- All women at average risk should start screening (testing) at age 25. Talk with your
healthcare provider about your risk.
- Women between ages 25 and 65 should have a primary HPV test every 5 years. A primary
HPV test is one that has been approved by the FDA to be done by itself for screening.
If primary HPV testing isn't available, screening can be done with either of these:
- Co-testing, which combines an HPV best with a Pap test every 5 years, or
- A Pap test alone every 3 years
- Women older than 65 who have had regular screening with normal results for the last
10 years and no history of serious cervical changes in the last 25 years can stop cervical cancer
screening. Once screening is stopped, it should not be started again.
- A woman who has had a hysterectomy with removal of the cervix for reasons not related
to cervical pre-cancer or cancer can stop screening.
- A woman who has had a hysterectomy without removal of the cervix should continue screening
according to the above guidelines.
- A woman who has been vaccinated against HPV should still follow the screening recommendations
for her age group.
HPV test, Pap test, and pelvic exam: The difference
A pelvic exam is not an HPV or Pap test, but they are usually done at the same time.
The HPV or Pap test is often done first. For the HPV test, the healthcare provider
puts a tool called a speculum into the vagina to hold it open, then gently scrapes
or brushes the cervix with another tool to remove a small number of cells. This sample
is sent to the lab. The Pap test can be done at the same time as the HPV test, and
it's done the same way. During a pelvic exam, a healthcare provider checks the health
of a woman's uterus and ovaries by feeling them through the belly (abdomen). For the
exam, the provider puts one or two fingers into the vagina and presses to steady the
uterus. The other hand pushes on the abdomen to feel the uterus and ovaries. A pelvic
exam cannot find cervical cancer in its early stages or abnormal cervical cells.
